Fields have been -modified, builders work differently, function arguments have changed, and some types are no longer -exposed. - -Additionally, osu!catch has finally been updated to match osu!lazer as closely as possible, just -like the other modes already did. - -- Beatmap converts - - Each mode now has a [ZST], i.e. `Osu`, `Taiko`, `Catch`, and `Mania`, which are used to specify - a mode at compile-time. Most of their utility comes from the new `IGameMode` trait. - - Each mode's calculators now require `Converted` beatmaps to make sure they're valid for the - mode, e.g. the `TaikoPerformance` calculator no longer takes a simple `Beatmap` but a - `Converted<'_, Taiko>` (or its alias `TaikoBeatmap<'_>`). - - Conversion between `Beatmap` and `Converted<'_, M>` either - - is essentially a free operation if the map's mode already matches `M`, - - or performs the required conversion by modifying hitobjects & co, - - or indicates an error due to incompatible mode conversion, e.g. a mania map cannot be - converted to a taiko map -- Difficulty calculation - - The `Difficulty` type is the core of all difficulty calculations and acts as a builder to - specify various parameters. - - To calculate values for a specific mode, the method `Difficulty::with_mode` will produce a - builder to calculate values for that mode. - - Recycled attributes are only valid if *all* difficulty parameters match, i.e. it must be on - the same map, use the same mods, clock rate, custom beatmap attributes, and passed object count - (and hardrock offset for osu!catch). - - Clockrate is now always clamped between 0.01 and 100 and custom beatmap attributes are clamped - between -20 and 20. -- Performance calculation - - Each mode's performance calculator was renamed from `[Mode]PP` to `[Mode]Performance` and - `AnyPP` is now called `Performance`. - - Difficulty attributes now contain a few more values so that the beatmap is no longer necessary - for performance calculation as long as difficulty attributes are available. - - The functions `[Mode]Performance::new` now take an argument implementing the trait - `Into(Mode)Performance`, i.e. either a beatmap (as before), or attributes (difficulty or - performance). Since attributes speed up the calculation, they should be prefered whenever - available. However, be mindful that they have been calculated for the same map and difficulty - settings. Otherwise, the final attributes will be incorrect. -- Features - - The `tracing` feature has been added. Its sole functionality is that errors during beatmap - parsing will emit a `tracing` event on the `ERROR` level. If this features is not explicitely - enabled, parsing errors will be ignored entirely. - - The `gradual` features has been removed. Types for gradual calculation are now always available. - - The `sync` feature has been added. Taiko's gradual calculation types contain types that are not - thread-safe by default. Enabling this feature will add some performance penalty but use types - that *do* allow moving gradual calculation across threads. - - The `compact_strains` feature is now enabled by default and causes strain values during - difficulty calculation to be stored in a space-efficient way to prevent out-of-memory issues on - maliciously long maps. This comes at a small performance cost. -- Misc - - Async is no longer supported. Beatmap parsing now works through [rosu-map] - which does not support async since evidently it's generally slower than regular sequential code. - - Errors while *parsing* a beatmap will never be propagated. The only errors that will be - propagated are those occuring while *decoding*, e.g. a file couldn't be read or other IO errors. - Notably, this means that some content is now parsed successfully into a `Beatmap` whereas in - previous `rosu-pp` versions it would error, e.g. an empty file is now a valid `Beatmap`. - - Although new lazer mods such as `DifficultyAdjust` or `DoubleTime` with a custom clockrate are - essentially supported by providing methods to specify their parameters, mods themselves are still - specified by their bit value. This means: - - `Daycore` will not be considered unless its clockrate change is explicitly specified - - /!\\ `Blinds` will not be considered for osu! performance calculation /!\\ - - Most `usize` types are now `u32`, e.g. fields of `ScoreState` or `max_combo` in attributes. - - `n_misses` has generally been renamed to `misses` for both fields and methods. - - Types such as `NestedObjectKind`, `ManiaObject`, or `Mods` that were only used for internal - calculations are no longer publicly exposed. - -# v0.10.0 (2023-11-19) - -Essentially only adjustments to the API so bindings won't need an update. - -- __Additions:__ - - Added `From` impl for `GameMode` - - Added the method `AnyPP::hitresult_priority` - - Added the method `[Mode]PP::generate_state` which returns the score state that will be used for performance calculation ([#23]) - - The struct `SortedVec` has now an improved public interface so it can be constructed and pushed onto ([#22]) - -- __Breaking adjustments:__ - - Removed the method `HitObject::end_time` from the public api. ([#25]) - - The fields `control_points` and `edge_sounds` of `HitObjectKind::Slider` are now stored in a `Box` rather than a `Vec`. ([#26]) - - Overhauled gradual calculation. All relevant types are now gated behind the `gradual` feature which must be enabled. ([#24]) - - `*GradualDifficultyAttributes` has been renamed to `*GradualDifficulty` and `*GradualPerformanceAttributes` - has been renamed to `*GradualPerformance`. - - Types for gradual calculation that depend on a lifetime now have a counterpart without a lifetime that might clone - underlying data along the way. E.g. now there is `CatchOwnedGradualDifficulty` and `[Mode]OwnedGradualPerformance`. - - `OsuGradualDifficulty` and thus `GradualDifficulty` no longer implement `Clone`. - - Gradual performance calculators' method `process_next_object` has been renamed to `next` and `process_next_n_objects` - has been renamed to `nth`. They now also have the new method `last`. - - Similar to `Iterator::nth`, gradual performance calculators' method `nth` is now zero-indexed i.e. passing `n=0` - will process 1 object, `n=1` will process 2, and so on. - -## v0.9.5 (2023-09-06) - -- __Additions:__ - - Added the method `{AnyStars/AnyPP}::is_convert` which **needs** to be used if the map was manually converted beforehand - -- __Adjustments:__ - - Specified clock rates can go below 0.001 again - -- __Fixes:__ - - Fixed underflow for osu!std scores that were FCs but quit mid-slider - - Fixed panic on incorrect file headers ([#21]) - -## v0.9.4 (2023-02-09) - -- __Additions:__ - - Added the method `{TaikoPP/ManiaPP}::is_convert` which **needs** to be used if the map was manually converted beforehand - -- __Adjustments:__ - - Specified clock rates can no longer go below 0.001 to prevent crashing due to memory hogging. - - (technically breaking) The only reasons for parsing to fail are now IO errors or invalid file headers. All other `ParseError` variants have been removed and instead of throwing an error the line is just ignored. - -- __Fixes:__ - - The `Beatmap::bpm` method now works properly by considering the most common beat length instead of just the first one - -## v0.9.3 (2023-01-28) - -- __Additions:__ - - Added the method `ScoreState::total_hits` - - Added the trait methods `BeatmapExt::{mode}_hitobjects` which return a list of mode-specific processed `HitObject`s ([#20]) - -- __Fixes:__ - - Lines with invalid curve points are now ignored instead of throwing an error while parsing - - Fixed a niche capacity overflow in curve generation - -## v0.9.2 (2022-11-08) - -- __Adjustments:__ - - When passing an osu!std map to `TaikoGradualDifficultyAttributes` or `ManiaGradualDifficultyAttributes`, it now automatically converts the map internally.
