 * Add an option for creating a mem db with no mutex

+- Add `ForceCopmact` to goleveldb database

+
+**Important note:** Version v0.6.5 was accidentally tagged and should be

+has updated the version marker so that normal `go get` upgrades will not
+require modifying existing use of v0.6.4.
+
+### Version bumps (since v0.6.4)
+
+- Bump grpc from to 1.42.0.
+- Bump dgraph/badger to v2 2.2007.3.
+- Bump go.etcd.io/bbolt to 1.3.6.
+
+## 0.6.5

+**2021-08-04**
+
+**Important note**: This version was tagged by accident, and should not be
+used. The tag now points to the [package-reorg

+any existing dependencies should not break.

+# How To Release tm db
+
+This document provides a step-by-step guide for creating a release of tm-db.
+
+## 1. Update the changelog
+
+Open the `CHANGELOG.md` at the root of the repository. 
+Amend the top of this file with a section for the latest version (0.6.x etc).
+Be sure to include any bug fixes, improvements, dependency upgrades, and breaking changes included in this version. 
+(It's OK to exclude changes to tooling dependencies, like updates to Github Actions.)
+Finally, create a pull request for the changelog update.
+Once the tests pass and the pull request is approved, merge the change into master.
+
+## 2. Tag the latest commit with the latest version
+
+tm-db is provided as a golang [module](https://blog.golang.org/publishing-go-modules), which rely on git tags for versioning information. 
+
+Tag the changelog commit in master created in step 1 with the latest version.
+Be sure to prefix the version tag with `v`. For example, `v0.6.5` for version 0.6.5.
+This tagging can be done [using github](https://docs.github.com/en/desktop/contributing-and-collaborating-using-github-desktop/managing-commits/managing-tags#creating-a-tag) or [using git](https://git-scm.com/book/en/v2/Git-Basics-Tagging) on the command line. 
+
+Note that the golang modules tooling expects tags to be immutable. 
+If you make a mistake after pushing a tag, make a new tag and start over rather than fix and re-push the old tag.
+## 3. Create a github release
+
+Finally, create a github release.
+To create a github release, follow the steps in the [github release documentation](https://docs.github.com/en/github/administering-a-repository/releasing-projects-on-github/managing-releases-in-a-repository#creating-a-release).
+
+When creating the github release, select the `Tag version` created in step 2. 
+Use the version tag as the release title and paste in the changelog information for this release in the `Describe this release` section.
