+Rewrite jsPsych's core logic. The following breaking changes have been made:
+
+**Timeline Events**
+
+- `conditional_function` is no longer executed on every iteration of a looping timeline, but only once before running the first trial of the timeline. If you rely on the old behavior, move your `conditional_function` into a nested timeline instead.
+- `on_timeline_start` and `on_timeline_finish` are no longer invoked in every repetition of a timeline, but only at the beginning or at the end of the timeline, respectively. If you rely on the old behavior, move the `on_timeline_start` and `on_timeline_finish` callbacks into a nested timeline.
+
+**Timeline Variables**
+
+- The functionality of `jsPsych.timelineVariable()` has been explicitly split into two functions, `jsPsych.timelineVariable()` and `jsPsych.evaluateTimelineVariable()`. Use `jsPsych.timelineVariable()` to create a timeline variable placeholder and `jsPsych.evaluateTimelineVariable()` to retrieve a given timeline variable's current value.
+- `jsPsych.evaluateTimelineVariable()` now throws an error if a variable is not found.
+
+**Progress Bar**
+
+- `jsPsych.setProgressBar(x)` has been replaced by `jsPsych.progressBar.progress = x`
+- `jsPsych.getProgressBarCompleted()` has been replaced by `jsPsych.progressBar.progress`
+- The automatic progress bar updates after every trial now, including trials in nested timelines.
+
+**Data Handling**
+
+- Timeline nodes no longer have IDs. As a consequence, the `internal_node_id` trial result property and `jsPsych.data.getDataByTimelineNode()` have been removed.
+- Unlike previously, the `save_trial_parameters` parameter can only be used to remove parameters that are specified in the plugin's info object. Other result properties will be left untouched.
+
+**Miscellaneous Changes**
+
+- `endExperiment()` and `endCurrentTimeline()` have been renamed to `abortExperiment()` and `abortCurrentTimeline()`, respectively.
+- Interaction listeners are now removed when the experiment ends.
+- JsPsych now internally relies on the JavaScript event loop. This means unit tests have to `await` utility functions like `pressKey()` to let the event loop proceed.

@@ -30,4 +30,5 @@ Rewrite jsPsych's core logic. The following breaking changes have been made:
 - `jsPsych.endExperiment()` and `jsPsych.endCurrentTimeline()` have been renamed to `jsPsych.abortExperiment()` and `jsPsych.abortCurrentTimeline()`, respectively.
 - `jsPsych.getAllTimelineVariables()` has been replaced by a trial-level `save_timeline_variables` parameter that can be used to include all or some timeline variables in a trial's result data.
 - Interaction listeners are now removed when the experiment ends.
+- JsPsych will now throw an error when a non-array value is used for a trial parameter marked as `array: true` in the plugin's info object.
 - JsPsych now internally relies on the JavaScript event loop. This means automated tests have to `await` utility functions like `pressKey()` to process the event loop.

+- Make `button_html` a function parameter which, given a choice's text and its index, returns the HTML string of the choice's button. If you were previously passing a string to `button_html`, like ``, you can now pass the function
+  ```js
+  function (choice) {
+    return '";
+  }
+  ```
+  Similarly, if you were using the array syntax, like
+  ```js
+  ['', '', '']
+  ```
+  an easy way to migrate your trial definition is to pass a function which accesses your array and replaces the `%choice%` placeholder:
+  ```js
+  function (choice, choice_index) {
+    return ['', '', ''][choice_index].replace("%choice%", choice);
+  }
+  ```
+  From there on, you can further simplify your function. For instance, if the intention of the above example is to have alternating button classes, the `button_html` function might be rewritten as
+  ```js
+  function (choice, choice_index) {
+    return '";
+  }
+  ```
+- Simplify the button DOM structure and styling: Buttons are no longer wrapped in individual container `div`s for spacing and `data-choice` attributes. Instead, each button is assigned its `data-choice` attribute and all buttons are direct children of the button group container `div`. The container `div`, in turn, utilizes a flexbox layout to position the buttons.

+# Migrating an experiment to v8.x
+
+Version 8.x of jsPsych focused on a complete rewrite of the core library to enable new features and make it easier to maintain.
+Most of the changes in version 8.x are behind the scenes.
+However, there are some breaking changes that you will need to address in your experiment code in order to upgrade to v8.x.
+
+This guide is aimed at upgrades from version 7.x to 8.x. 
+If you are using version 6.x or earlier, please follow the [migration guide for v7.x](./migration-v7.md) before trying to upgrade to v8.x.
+
+## Timeline Events
+
+In version 7.x, if a timeline had a `conditional_function` it would be checked on every iteration if the timeline also looped. 
+In version 8.x, the `conditional_function` is checked only before the first trial on the timeline. 
+We think this is a more intuitive behavior. 
+It allows the `conditional_function` to toggle whether a timeline runs at all, and once it starts running we assume that it should continue.
+If you relied on the old behavior, you can nest the timeline with the `conditional_function` inside another timeline that loops.
+
+We've also changed the behavior of `on_timeline_start` and `on_timeline_finish` to only execute one time each. 
+Previously these events executed on every repetition of a timeline. 
+If you relied on the old behavior, you can nest the timeline with the `on_timeline_start` or `on_timeline_finish` inside the timeline that repeats.
+
+## Timeline Variables
+
+We've split the functionality of `jsPsych.timelineVariable()` into two different functions to reflect the two different use cases. 
+If you are using `jsPsych.timelineVariable()` inside a function you will need to replace the function call with `jsPsych.evaluateTimelineVariable()`. 
+Usage as a parameter in a trial doesn't change.
+
+This behavior is still the same:
+```js
+const trial = {
+  type: jsPsychHtmlKeyboardResponse,
+  stimulus: jsPsych.timelineVariable('stimulus'),
+}
+```
+
+This behavior has changed:
+```js
+const trial = {
+  type: jsPsychHtmlKeyboardResponse,
+  stimulus: () => {
+    return `
The stimulus is ${jsPsych.evaluateTimelineVariable('stimulus')}
`
+  }
+}
+```
+
+We've added some better error support for `evaluateTimelineVariable()` so that it will throw an error if there's no corresponding timeline variable to evaluate. 
+
+We've removed support for `jsPsych.getAllTimelineVariables()` and replaced it with the trial-level property `save_timeline_variables`. 
+If you need to save timeline variables to jsPsych's data, you can set `save_timeline_variables: true` in the trial.
+
+## Trial parameters
+
+We've made some trial parameters more strict to improve the maintainability of the library.
+
+If a plugin has a parameter that is marked as `array: true` in the plugin's `info` object, then jsPsych will now throw an error if the parameter is not an array. 
+Previously, some plugins allowed some parameters to be either an array or non-array. 
+For the plugins included in jsPsych's main repository, the only affected parameter is the `button_html` parameter for the various button response plugins. 
+Previously this parameter could be an array or a string. 
+We've now made it so that it must be a function. 
+
+Version 7.x:
+```js
+const trial = {
+  type: jsPsychHtmlButtonResponse,
+  stimulus: 'Press a button',
+  choices: ['a', 'b', 'c'],
+  button_html: ''
+}
+```
+
+Version 8.x:
+```js
+const trial = {
+  type: jsPsychHtmlButtonResponse,
+  stimulus: 'Press a button',
+  choices: ['a', 'b', 'c'],
+  button_html: (choice) => {
+    return ``
+  }
+}
+```
+
+The `button_html` parameter can also support different HTML for each button. 
+See the [plugin documentation](https://www.jspsych.org/plugins/jspsych-html-button-response/) for more details.
+
+## Plugin parameter handling
+
+In version 7.x, a plugin could omit parameters from the `info` object and jsPsych would still evaluate these parameters appropriately in most cases. 
+Version 8.x is more strict about this.
+Plugins should list all parameters in the `info` object.
+If a parameter is not listed, then timeline variables and function evaluation will not work for that parameter. The `save_trial_parameters` parameter will also not work for parameters that are not listed in the `info` object.
+
+## Progress bar
+
+The automatic progress bar now updates after every trial, including trials in nested timelines. 
+If you would like to implement the old behavior of updating only on the top-level timeline, you can manually control the progress bar using the `on_finish` callback of the timelines and trials in the top-level timeline.
+
+We've also changed `jsPsych.setProgressBar(x)` to `jsPsych.progressBar.progress = x`.
+And we've changed `jsPsych.getProgressBarCompleted()` to `jsPsych.progressBar.progress`.
+This simplifies the API for the progress bar.
+
+## Data Handling
+
+We've removed `internal_node_id` and `jsPsych.data.getDataByTimelineNode()`. 
+Timeline node IDs were used internally by jsPsych to keep track of experiment progress in version 7, but this is no longer the case in version 8. 
+Most users didn't need or want to see the `internal_node_id` in the data, so we've removed it. 
+If you relied on this parameter, the simplest replacement is probably to use the `data` parameter to add the information you need back to the timeline.
+
+## Ending a timeline and ending the experiment
+
+We've renamed `jsPsych.endExperiment()` to `jsPsych.abortExperiment()`.
+
+We've renamed `jsPsych.endCurrentTimeline()` to `jsPsych.abortCurrentTimeline()`.
+
+## Interaction listeners
+
+In version 7.x, interaction events (like exiting fullscreen) would still be listened for even after the experiment ended. 
+These events are no longer reported once the experiment ends.
+
+## Need help?
+
+If you encounter issues migrating code to v8.x please open a thread on our [discussion board](https://github.com/jspsych/jsPsych/discussions/).

-The progress bar updates after every node on the top-level timeline updates. This avoids distracting updates in the middle of trials that are composed of multiple plugins, or confusing updates due to looping or conditional structures that may or may not execute depending on the actions of the participant. This also allows some flexibility for the programmer; by nesting timelines in a deliberate manner, the timing of progress bar updates can be controlled.
+The progress bar automatically updates after every trial.
 
 ## Manual Control
 
-The progress bar can also be manually controlled using the function `jsPsych.setProgressBar()`. This function takes a numeric value between 0 and 1, representing the proportion of the progress bar to fill.
+The progress bar can also be manually controlled by setting `jsPsych.progressBar.progress`. The value of `jsPsych.progressBar.progress` should be a number between 0 and 1. For example, to set the progress bar to 85% full, you would do this:
+
 
 ```js
-var trial = {

 	type: jsPsychHtmlKeyboardResponse,
 	stimulus: 'Almost done...',
 	on_finish: function(){

+# Migrating an experiment to v8.x
+
+Version 8.x of jsPsych focused on a complete rewrite of the core library to enable new features and make it easier to maintain.
+Most of the changes in version 8.x are behind the scenes.
+However, there are some breaking changes that you will need to address in your experiment code in order to upgrade to v8.x.
+
+This guide is aimed at upgrades from version 7.x to 8.x. 
+If you are using version 6.x or earlier, please follow the [migration guide for v7.x](./migration-v7.md) before trying to upgrade to v8.x.
+
+## Timeline Events
+
+In version 7.x, if a timeline had a `conditional_function` it would be checked on every iteration if the timeline also looped. 
+In version 8.x, the `conditional_function` is checked only before the first trial on the timeline. 
+We think this is a more intuitive behavior. 
+It allows the `conditional_function` to toggle whether a timeline runs at all, and once it starts running we assume that it should continue.
+If you relied on the old behavior, you can nest the timeline with the `conditional_function` inside another timeline that loops.
+
+We've also changed the behavior of `on_timeline_start` and `on_timeline_finish` to only execute one time each. 
+Previously these events executed on every repetition of a timeline. 
+If you relied on the old behavior, you can nest the timeline with the `on_timeline_start` or `on_timeline_finish` inside the timeline that repeats.
+
+## Timeline Variables
+
+We've split the functionality of `jsPsych.timelineVariable()` into two different functions to reflect the two different use cases. 
+If you are using `jsPsych.timelineVariable()` inside a function you will need to replace the function call with `jsPsych.evaluateTimelineVariable()`. 
+Usage as a parameter in a trial doesn't change.
+
+This behavior is still the same:
+```js
+const trial = {
+  type: jsPsychHtmlKeyboardResponse,
+  stimulus: jsPsych.timelineVariable('stimulus'),
+}
+```
+
+This behavior has changed:
+```js
+const trial = {
+  type: jsPsychHtmlKeyboardResponse,
+  stimulus: () => {
+    return `
The stimulus is ${jsPsych.evaluateTimelineVariable('stimulus')}
`
+  }
+}
+```
+
+We've added some better error support for `evaluateTimelineVariable()` so that it will throw an error if there's no corresponding timeline variable to evaluate. 
+
+We've removed support for `jsPsych.getAllTimelineVariables()` and replaced it with the trial-level property `save_timeline_variables`. 
+If you need to save timeline variables to jsPsych's data, you can set `save_timeline_variables: true` in the trial.
+
+## Trial parameters
+
+We've made some trial parameters more strict to improve the maintainability of the library.
+
+If a plugin has a parameter that is marked as `array: true` in the plugin's `info` object, then jsPsych will now throw an error if the parameter is not an array. 
+Previously, some plugins allowed some parameters to be either an array or non-array. 
+For the plugins included in jsPsych's main repository, the only affected parameter is the `button_html` parameter for the various button response plugins. 
+Previously this parameter could be an array or a string. 
+We've now made it so that it must be a function. 
+
+Version 7.x:
+```js
+const trial = {
+  type: jsPsychHtmlButtonResponse,
+  stimulus: 'Press a button',
+  choices: ['a', 'b', 'c'],
+  button_html: ''
+}
+```
+
+Version 8.x:
+```js
+const trial = {
+  type: jsPsychHtmlButtonResponse,
+  stimulus: 'Press a button',
+  choices: ['a', 'b', 'c'],
+  button_html: (choice) => {
+    return ``
+  }
+}
+```
+
+The `button_html` parameter can also support different HTML for each button. 
+See the [plugin documentation](https://www.jspsych.org/plugins/jspsych-html-button-response/) for more details.
+
+## Plugin parameter handling
+
+In version 7.x, a plugin could omit parameters from the `info` object and jsPsych would still evaluate these parameters appropriately in most cases. 
+Version 8.x is more strict about this.
+Plugins should list all parameters in the `info` object.
+If a parameter is not listed, then timeline variables and function evaluation will not work for that parameter. The `save_trial_parameters` parameter will also not work for parameters that are not listed in the `info` object.
+
+## Progress bar
+
+The automatic progress bar now updates after every trial, including trials in nested timelines. 
+If you would like to implement the old behavior of updating only on the top-level timeline, you can manually control the progress bar using the `on_finish` callback of the timelines and trials in the top-level timeline.
+
+We've also changed `jsPsych.setProgressBar(x)` to `jsPsych.progressBar.progress = x`.
+And we've changed `jsPsych.getProgressBarCompleted()` to `jsPsych.progressBar.progress`.
+This simplifies the API for the progress bar.
+
+## Data Handling
+
+We've removed `internal_node_id` and `jsPsych.data.getDataByTimelineNode()`. 
+Timeline node IDs were used internally by jsPsych to keep track of experiment progress in version 7, but this is no longer the case in version 8. 
+Most users didn't need or want to see the `internal_node_id` in the data, so we've removed it. 
+If you relied on this parameter, the simplest replacement is probably to use the `data` parameter to add the information you need back to the timeline.
+
+## Ending a timeline and ending the experiment
+
+We've renamed `jsPsych.endExperiment()` to `jsPsych.abortExperiment()`.
+
+We've renamed `jsPsych.endCurrentTimeline()` to `jsPsych.abortCurrentTimeline()`.
+
+## Interaction listeners
+
+In version 7.x, interaction events (like exiting fullscreen) would still be listened for even after the experiment ended. 
+These events are no longer reported once the experiment ends.
+
+## Need help?
+
+If you encounter issues migrating code to v8.x please open a thread on our [discussion board](https://github.com/jspsych/jsPsych/discussions/).

-The progress bar updates after every node on the top-level timeline updates. This avoids distracting updates in the middle of trials that are composed of multiple plugins, or confusing updates due to looping or conditional structures that may or may not execute depending on the actions of the participant. This also allows some flexibility for the programmer; by nesting timelines in a deliberate manner, the timing of progress bar updates can be controlled.
+The progress bar automatically updates after every trial.
 
 ## Manual Control
 
-The progress bar can also be manually controlled using the function `jsPsych.setProgressBar()`. This function takes a numeric value between 0 and 1, representing the proportion of the progress bar to fill.
+The progress bar can also be manually controlled by setting `jsPsych.progressBar.progress`. The value of `jsPsych.progressBar.progress` should be a number between 0 and 1. For example, to set the progress bar to 85% full, you would do this:

 Each object on the timeline can also have it's own timeline. This is useful for many reasons. One is that it allows you to define common parameters across trials once and have them apply to all the trials on the nested timeline.

+
+Sometimes you may want to skip data collection for a particular trial. This can be done by setting the `record_data` parameter to `false`. This is useful if you want your data output to only contain the trials that collect relevant responses from the participant. For example, you might want to skip data collection for trials that just present a fixation cross for a fixed period of time.

 When accessing the data with `jsPsych.data.get()` the returned object is a special data collection object that exposes a number of methods for aggregating and manipulating the data. The full list of methods is detailed in the [data module documentation](../reference/jspsych-data.md).

- * **audio-keyboard-response**

+ * If the browser supports it, audio files are played using the WebAudio API. This allows for reasonably precise timing of the
+ * playback. The timing of responses generated is measured against the WebAudio specific clock, improving the measurement of
+ * response times. If the browser does not support the WebAudio API, then the audio file is played with HTML5 audio.
+ *
+ * Audio files can be automatically preloaded by jsPsych using the [`preload` plugin](preload.md). However, if you are using
+ * timeline variables or another dynamic method to specify the audio stimulus, then you will need to [manually preload](../overview/media-preloading.md#manual-preloading) the audio.
  *
- * jsPsych plugin for playing an audio file and getting a keyboard response
+ * The trial can end when the participant responds, when the audio file has finished playing, or if the participant has
+ * failed to respond within a fixed length of time. You can also prevent a keyboard response from being recorded before
+ * the audio has finished playing.

 /**
- * html-audio-response
- * jsPsych plugin for displaying a stimulus and recording an audio response through a microphone
+ * This plugin displays HTML content and records audio from the participant via a microphone.
+ *
+ * In order to get access to the microphone, you need to use the [initialize-microphone plugin](initialize-microphone.md) on your timeline prior to using this plugin.
+ * Once access is granted for an experiment you do not need to get permission again.
+ *
+ * This plugin records audio data in [base 64 format](https://developer.mozilla.org/en-US/docs/Glossary/Base64).
+ * This is a text-based representation of the audio which can be coverted to various audio formats using a variety of [online tools](https://www.google.com/search?q=base64+audio+decoder) as well as in languages like python and R.
+ *
+ * **This plugin will generate a large amount of data, and you will need to be careful about how you handle this data.**
+ * Even a few seconds of audio recording will add 10s of kB to jsPsych's data.
+ * Multiply this by a handful (or more) of trials, and the data objects will quickly get large.
+ * If you need to record a lot of audio, either many trials worth or just a few trials with longer responses, we recommend that you save the data to your server immediately after the trial and delete the data in jsPsych's data object.
+ * See below for an example of how to do this.
+ *
+ * This plugin also provides the option to store the recorded audio files as [Object URLs](https://developer.mozilla.org/en-US/docs/Web/API/URL/createObjectURL) via `save_audio_url: true`.
+ * This will generate a URL that is storing a copy of the recorded audio, which can be used for subsequent playback.
+ * See below for an example where the recorded audio is used as the stimulus in a subsequent trial.
+ * This feature is turned off by default because it uses a relatively large amount of memory compared to most jsPsych features.
+ * If you are running an experiment where you need this feature and you are recording lots of audio snippets, you may want to manually revoke the URLs when you no longer need them using [`URL.revokeObjectURL(objectURL)`](https://developer.mozilla.org/en-US/docs/Web/API/URL/revokeObjectURL).
+ *
+ * !!! warning
+ *     When recording from a microphone your experiment will need to be running over `https://` protocol. If you try to run the experiment locally using the `file://` protocol or over `http://` protocol you will not be able to access the microphone because of [potential security problems](https://blog.mozilla.org/webrtc/camera-microphone-require-https-in-firefox-68/).

 /**
- * html-video-response
- * jsPsych plugin for displaying a stimulus and recording a video response through a camera
+ *
+ * This plugin displays HTML content and records video from the participant via a webcam.
+ *
+ * In order to get access to the camera, you need to use the [initialize-camera plugin](initialize-camera.md) on your timeline prior to using this plugin.
+ * Once access is granted for an experiment you do not need to get permission again.
+ *
+ * This plugin records video data in [base 64 format](https://developer.mozilla.org/en-US/docs/Glossary/Base64).
+ * This is a text-based representation of the video which can be coverted to various video formats using a variety of [online tools](https://www.google.com/search?q=base64+video+decoder) as well as in languages like python and R.
+ *
+ * **This plugin will generate a large amount of data, and you will need to be careful about how you handle this data.**
+ * Even a few seconds of video recording will add 10s of kB to jsPsych's data.
+ * Multiply this by a handful (or more) of trials, and the data objects will quickly get large.
+ * If you need to record a lot of video, either many trials worth or just a few trials with longer responses, we recommend that you save the data to your server immediately after the trial and delete the data in jsPsych's data object.
+ * See below for an example of how to do this.
+ *
+ * This plugin also provides the option to store the recorded video files as [Object URLs](https://developer.mozilla.org/en-US/docs/Web/API/URL/createObjectURL) via `save_video_url: true`.
+ * This will generate a URL that stores a copy of the recorded video, which can be used for subsequent playback during the experiment.
+ * See below for an example where the recorded video is used as the stimulus in a subsequent trial.
+ * This feature is turned off by default because it uses a relatively large amount of memory compared to most jsPsych features.
+ * If you are running an experiment where you need this feature and you are recording lots of video clips, you may want to manually revoke the URLs when you no longer need them using [`URL.revokeObjectURL(objectURL)`](https://developer.mozilla.org/en-US/docs/Web/API/URL/revokeObjectURL).
+ *
+ * !!! warning
+ *     When recording from a camera your experiment will need to be running over `https://` protocol.
+ * If you try to run the experiment locally using the `file://` protocol or over `http://` protocol you will not
+ * be able to access the camera because of
+ * [potential security problems](https://blog.mozilla.org/webrtc/camera-microphone-require-https-in-firefox-68/).

 /**
- * **sketchpad**
+ * This plugin creates an interactive canvas that the participant can draw on using their mouse or touchscreen.
+ * It can be used for sketching tasks, like asking the participant to draw a particular object.
+ * It can also be used for some image segmentation or annotation tasks by setting the `background_image` parameter to render an image on the canvas.
+ *
+ * The plugin stores a [base 64 data URL representation](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs) of the final image.
+ * This can be converted to an image file using [online tools](https://www.google.com/search?q=base64+image+decoder) or short programs in [R](https://stackoverflow.com/q/58604195/3726673), [python](https://stackoverflow.com/q/2323128/3726673), or another language of your choice.
+ * It also records all of the individual strokes that the participant made during the trial.
+ *
+ * !!! warning
+ *     This plugin generates **a lot** of data. Each trial can easily add 500kb+ of data to a final JSON output.
+ *     You can reduce the amount of data generated by turning off storage of the individual stroke data (`save_strokes: false`) or storage of the final image (`save_final_image: false`) if your use case doesn't require that information.
+ *     If you are going to be collecting a lot of data with this plugin you may want to save your data to your server after each trial and not wait until the end of the experiment to perform a single bulk upload.
+ *     You can do this by putting data saving code inside the [`on_data_update` event handler](../overview/events.md#on_data_update).

 /**
- * **survey**
+ * SurveyJS version: 1.9.138
+ *
+ * This plugin is a wrapper for the [**SurveyJS form library**](https://surveyjs.io/form-library/documentation/overview). It displays survey-style questions across one or more pages. You can mix different question types on the same page, and participants can navigate back and forth through multiple survey pages without losing responses. SurveyJS provides a large number of built-in question types, response validation options, conditional display options, special response options ("None", "Select all", "Other"), and other useful features for building complex surveys. See the [Building Surveys in jsPsych](../overview/building-surveys.md) page for a more detailed list of all options and features.
+ *
+ * With SurveyJS, surveys can be defined using a JavaScript/JSON object, a JavaScript function, or a combination of both. The jsPsych `survey` plugin provides parameters that accept these methods of constructing a SurveyJS survey, and passes them into SurveyJS. The fact that this plugin just acts as a wrapper means you can take advantage of all of the SurveyJS features, and copy/paste directly from SurveyJS examples into the plugin's `survey_json` parameter (for JSON object configuration) or `survey_function` parameter (for JavaScript code).
+ *
+ * This page contains the plugin's reference information and examples. The [Building Surveys in jsPsych](../overview/building-surveys.md) page contains a more detailed guide for using this plugin.
+ *
+ * For the most comprehensive guides on survey configuration and features, please see the [SurveyJS form library documentation](https://surveyjs.io/form-library/documentation/overview) and [examples](https://surveyjs.io/form-library/examples/overview).
+ *
+ * !!! warning "Limitations"
+ *
+ *     The jsPsych `survey` plugin is not compatible with certain jsPsych and SurveyJS features. Specifically:
+ *
+ *     - **It is not always well-suited for use with jsPsych's [timeline variables](../overview/timeline.md#timeline-variables) feature.** This is because the timeline variables array must store the entire `survey_json` object for each trial, rather than just the parameters that change across trials, which are nested within the `survey_json` object. We offer some alternative methods for dynamically constructing questions/trials in [this section](../overview/building-surveys.md#defining-survey-trialsquestions-programmatically) of the Building Surveys in jsPsych documentation page.
+ *     - **It does not support the SurveyJS "[complete page](https://surveyjs.io/form-library/documentation/design-survey/create-a-multi-page-survey#complete-page)" parameter.** This is a parameter for HTML formatted content that should appear after the participant clicks the 'submit' button. Instead of using this parameter, you should create another jsPsych trial that comes after the survey trial to serve the same purpose.
+ *     - **It does not support the SurveyJS question's `correctAnswer` property**, which is used for SurveyJS quizzes and automatic response scoring. SurveyJS does not store this value or the response score in the data - instead this is only used to display scores on the survey's 'complete page'. Since the complete page is not supported, this 'correctAnswer' property also does not work as intended in the jsPsych plugin.

- * **video-slider-response**
+ * This plugin plays a video and allows the participant to respond by dragging a slider. The stimulus can be displayed
+ * until a response is given, or for a pre-determined amount of time. The trial can be ended automatically when the
+ * participant responds, when the video file has finished playing, or if the participant has failed to respond within
+ * a fixed length of time. You can also prevent the slider response from being made before the video has finished playing.
  *
- * jsPsych plugin for playing a video file and getting a slider response
+ * Video files can be automatically preloaded by jsPsych using the [`preload` plugin](preload.md). However, if you are
+ * using timeline variables or another dynamic method to specify the video stimulus, you will need to
+ * [manually preload](../overview/media-preloading.md#manual-preloading) the videos. Also note that video preloading
+ * is disabled when the experiment is running as a file (i.e. opened directly in the browser, rather than through a
+ * server), in order to prevent CORS errors - see the section on [Running Experiments](../overview/running-experiments.md) for more information.

- * **virtual-chinrest**
  *
- * jsPsych plugin for estimating physical distance from monitor and optionally resizing experiment content, based on Qisheng Li 11/2019. /// https://github.com/QishengLi/virtual_chinrest
+ * This plugin provides a "virtual chinrest" that can measure the distance between the participant and the screen. It
+ * can also standardize the jsPsych page content to a known physical dimension (e.g., ensuring that a 200px wide stimulus
+ * is 2.2cm wide on the participant's monitor). This is based on the work of [Li, Joo, Yeatman, and Reinecke
+ * (2020)](https://doi.org/10.1038/s41598-019-57204-1), and the plugin code is a modified version of
+ * [their implementation](https://github.com/QishengLi/virtual_chinrest). We recommend citing their work in any paper
+ * that makes use of this plugin.
+ *
+ * !!! note "Citation"

+ *
+ * The plugin works in two phases.
+ *
+ * **Phase 1**. To calculate the pixel-to-cm conversion rate for a participant’s display, participants are asked to place
+ * a credit card or other item of the same size on the screen and resize an image until it is the same size as the credit
+ * card. Since we know the physical dimensions of the card, we can find the conversion rate for the participant's display.
+ *
+ * **Phase 2**. To measure the participant's viewing distance from their screen we use a [blind spot]() task. Participants are asked to focus on a black square on the screen with their right eye closed, while a red dot repeatedly sweeps from right to left. They press the spacebar on their keyboard whenever they perceive that the red dot has disappeared. This part allows the plugin to use the distance between the black square and the red dot when it disappears from eyesight to estimate how far the participant is from the monitor. This estimation assumes that the blind spot is located at 13.5° temporally.

+The plugin's `info` property is an object with a `name`, `version`, `parameters`, and `data` property. 
 
 ```js
 const info = {
   name: 'my-awesome-plugin',
-  parameters: { }
+  version: version,
+  parameters: { },
+  data: { }
 }
 ```
 
+The `version` field should imported from the package.json file by including an import statement in the top of the index.ts file. This lets the `version` field be automatically updated with each changeset. 
+
 The `parameters` property is an object containing all of the parameters for the plugin. Each parameter has a `type` and `default` property.
 
+The `data` field is similar to the `parameters` property, except it does not include a `default` property. Additionally, the `data` describes data that is only generated, and should be only used for data you generate not the default data. Any javadoc you include will be scraped as metadata if you are choosing to generate metadata. 
+
 ```js
 const info = {
   name: 'my-awesome-plugin',
   parameters: { 
     image: {
-      type: jspsych.ParameterType.IMAGE,

 }
 ```

 If the `default` value is `undefined` then a user must specify a value for this parameter when creating a trial using the plugin on the timeline. If they do not, then an error will be generated and shown in the console. If a `default` value is specified in `info` then that value will be used by the plugin unless the user overrides it by specifying that property.
 
 jsPsych allows most [plugin parameters to be dynamic](../overview/dynamic-parameters.md), which means that the parameter value can be a function that will be evaluated right before the trial starts. However, if you want your plugin to have a parameter that is a function that _shouldn't_ be evaluated before the trial starts, then you should make sure that the parameter type is `'FUNCTION'`. This tells jsPsych not to evaluate the function as it normally does for dynamic parameters. See the `canvas-*` plugins for examples.

This event will happen once per experiment, unlike the other events which occur with each trial. The `params` object can include whatever parameters are necessary to configure the extension. The `params` object is passed from the call to `initJsPsych()` to `initialize()` method. `initialize()` must return a `Promise` that resolves when the extension is finished initializing.

 ### on_load()
 
 `on_load()` is called after the `on_load` event for the plugin has completed, which is typically when the plugin has finished executing initial DOM-modifying code and has set up various event listeners. This is where the extension can begin actively interacting with the DOM and recording data. The `params` object is passed from the declaration of the extension in the trial object. You can use `params` to customize the behavior of the extension for each trial.

 The `version` field describes the version of the extension used and then durin the experiment will be part of the generated data. This is used generate metadata and help maintain the Psych-DS standard. It should imported from the package.json file by including an import statement in the top of the index.ts file. This allows the `version` field be automatically updated with each changeset. If you are not using a build environment and instead writing a plain JS file, you can manually enter the `version` as a string as done in the comment.

 ### Optional methods
 
 The extension can also include any additional methods that are necessary for interacting with it. See the [webgazer extension](../extensions/webgazer.md) for an example.

 If the `default` value is `undefined` then a user must specify a value for this parameter when creating a trial using the plugin on the timeline. If they do not, then an error will be generated and shown in the console. If a `default` value is specified in `info` then that value will be used by the plugin unless the user overrides it by specifying that property.
 
 jsPsych allows most [plugin parameters to be dynamic](../overview/dynamic-parameters.md), which means that the parameter value can be a function that will be evaluated right before the trial starts. However, if you want your plugin to have a parameter that is a function that _shouldn't_ be evaluated before the trial starts, then you should make sure that the parameter type is `'FUNCTION'`. This tells jsPsych not to evaluate the function as it normally does for dynamic parameters. See the `canvas-*` plugins for examples.

 ### Waiting for specified durations
 
-If you need to delay code execution for a fixed amount of time, we recommend using jsPsych's wrapper of the `setTimeout()` function, `jsPsych.pluginAPI.setTimeout()`. In `7.0` the only advantage of using this method is that it registers the timeout handler so that it can be easily cleared at the end of the trial using `jsPsych.pluginAPI.clearAllTimeouts()`. In future versions we may replace the implementation of `jsPsych.pluginAPI.setTimeout()` with improved timing functionality based on `requestAnimationFrame`.

Any timeouts that are created using jsPsych's `setTimeout()` will be automatically cleared when the trial ends, which prevents one plugin from interfering with the timing of another plugin.

 If you would like to manually trigger the `on_load` event for a plugin, the `.trial()` method accepts an optional third parameter that is a callback function to invoke when loading is complete. 
 
-In order to tell jsPsych to *not* invoke the regular callback when the `.trial()` method returns, you need to explicitly return a `Promise`. As of version `7.0` this Promise only serves as a flag to tell jsPsych that the `on_load` event should not be triggered.

+In order to tell jsPsych to *not* invoke the regular callback when the `.trial()` method returns, you need to explicitly return a `Promise`. As of version `8.0`, we recommend making the `trial` function an `async` function to handle this.
 
 Here's a sketch of how the `on_load` event can be utilized in a plugin. Note that this example is only a sketch and leaves out all the stuff that happens between loading and finishing the trial. See the source for the `audio-keyboard-response` plugin for a complete exampe.

   let trial_complete;
 
-  do_something_asynchronous().then(()=>{
-    on_load();

 ```
 
+As of version `8.0` you may also return the data object from the `trial()` method when the method is an `async` function. This is equivalent to calling `jsPsych.finishTrial(data)`.
+
+```javascript
+constructor(jsPsych){
+  this.jsPsych = jsPsych;
+}
+
+async trial(display_element, trial){
+
+  let data = {
+    correct: true,
+    rt: 350
+  }
+
+  return data;
+}
+```
+
 The data recorded will be that `correct` is `true` and that `rt` is `350`. [Additional data for the trial](../overview/plugins.md#data-collected-by-all-plugins) will also be collected automatically.
 
+### When a plugin finishes
+
+When a plugin finishes, it should call `jsPsych.finishTrial()` or return a data object if the `trial()` method is an `async` function. This is how jsPsych knows to advance to the next trial in the experiment (or end the experiment if it is the last trial).

+As of version `8.0`, ending the trial will automatically clear the display element and automatically clear any timeouts that are still pending.

 We also recommend that you make your plugin *as general as possible*. Consider using parameters to give the user of the plugin as many options for customization as possible. For example, if you have any text that displays in the plugin including things like button labels, implement the text as a parameter. This allows users running experiments in other languages to replace text values as needed.
 
+## Plugin templates
+
+Templates for plugins are available in the [jspsych-contrib](https://github.com/jspsych/jspsych-contrib) repository. There is a command-line tool for generating a new plugin from these templates in that repository. See the README file in the jspsych-contrib repository for more information.

 Plugins should list all parameters in the `info` object.
 If a parameter is not listed, then timeline variables and function evaluation will not work for that parameter. The `save_trial_parameters` parameter will also not work for parameters that are not listed in the `info` object.

+We've added a `version` property to the `info` object for plugins.
+This property is a string that should be updated whenever a new version of the plugin is released.

+We've also added a `data` property to the `info` object for plugins.
+This property is an object that can contain a description of the types of data that the plugin will generate.
+
+Including these properties is not *required* for a plugin to work, but it is recommended.
+In version 8.x, jsPsych will throw a warning if a plugin is used that does not have a `version` or `data` property in the `info` object.
+In version 9.x, we plan to make this a requirement.
+
+## Changes to `finishTrial()`
+
+When a plugin calls `finishTrial()` or ends via a `return` statement, jsPsych will now automatically clear the display and clear any timeouts that are still pending. This change should only affect plugin developers. If you are using built-in plugins you should not notice any difference.

 ## Progress bar
 
 The automatic progress bar now updates after every trial, including trials in nested timelines.

+### getAudioPlayer
+
+```javascript
+jsPsych.pluginAPI.getAudioPlayer(filepath)
+```
+
+#### Return value
+
+Returns a Promise that resolves to an instance of an AudioPlayer class that holds the buffer of the audio file when it finishes loading.
+
+#### Description
+
+Gets an AudioPlayer class instance which has methods that can be used to play or stop audio that can be played with the WebAudio API or an audio object that can be played as HTML5 Audio. 
+
+It is strongly recommended that you preload audio files before calling this method. This method will load the files if they are not preloaded, but this may result in delays during the experiment as audio is downloaded.
+
+#### Examples
+
+##### HTML 5 Audio and WebAudio API
+
+```javascript
+const audio = await jsPsych.pluginAPI.getAudioPlayer('my-sound.mp3')
+
+audio.play()
+
+```
+
+See the `audio-keyboard-response` plugin for an example in a fuller context.

+```
+
+#### Return value
+
+Returns nothing.
+
+#### Description
+
+Method that belongs to the AudioPlayer class. Plays the audio loaded into the audio buffer of the AudioPlayer instance for a particular file. If the audio is a HTML5 audio object it plays it. If the audio is a Webaudio API object it starts it.
+
+#### Example
+
+##### HTML 5 Audio and WebAudio API
+
+```javascript
+const audio = await jsPsych.pluginAPI.getAudioPlayer('my-sound.mp3');

+Returns nothing.
+
+#### Description
+
+Method that belongs to the AudioPlayer class. Stops the audio loaded into the audio buffer of the AudioPlayer instance for a particular file. If the audio is an HTML5 audio object it pauses it. If the audio is a Webaudio API object it stops it.
