Version 4.1.0 bumps the peer dependency range for vue-tsc to ^2.1.0 because there was a breaking change in its API. If you're using Vue support, upgrade both packages simultaneously, e.g. npm i -D prettier-plugin-organize-imports vue-tsc.
Version 4.0.0 upgrades/replaces the Volar packages used for Vue support, to use the latest vue-tsc package that's part of Volar 2. To migrate, you just have to remove @volar/vue-typescript and if you're using it, also @volar/vue-language-plugin-pug, and replace it with vue-tsc and @vue/language-plugin-pug respectively. There are no breaking changes other than this.
Version 3.2.4 implements a fix to skip when formatting ranges (i.e. if the plugin is requested to format a range, it doesn't do anything because it would lack the full file context).
Version 3.2.3 updates the readme with instructions for Prettier 3.
Version 3.2.2 fixes a performance regression introduced in 3.2.0.
Version 3.2.1 fixes the implementation of the language service host's getCurrentDirectory method to return the directory containing the tsconfig, rather than using ts.sys.getCurrentDirectory (which returns process.cwd()). This should prevent issues with resolving compiler plugins with Volar (which is used for Vue support).
Version 3.2.0 adds and fixes support for pug templates in Vue files (via @volar/vue-language-plugin-pug). Please be aware that you'll need to update your version of the @volar/vue-typescript peer dependency from 0.x to 1.x.
Version 3.1.0 adds an option to skip destructive code actions like removing unused imports.
Version 3.0.3 fixes a performance regression introduced in 3.0.2.
Version 3.0.2 fixes a regression introduced by adding some file-system related methods to the language service host (to fix a bug), which revealed that another method's implementation was incorrect.
Version 3.0.1 bumps the @volar/vue-typescript version to fix more edge cases, e. g. not removing imports when a component is used via kebab-case naming. @volar/vue-typescript is now defined as an optional peer dependency and you'll need to install version 0.39 or later. Furthermore a fix has been added that should help support more module resolution algorithms.
Version 3.0.0 switches to a different package for Vue support, which fixes some more issues, e. g. support for setup scripts. No breaking changes otherwise.
Version 2.3.4 fixes an issue with Vue v2 files.
Version 2.3.3 fixes a bug where default imports were removed erroneously.
Version 2.3.1 adds debug logs and fixes Vue.js support.
Version 2.2.0 adds a compiler options cache to improve performance.
Version 2.1.0 adds support for Vue.js (.vue files).
Version 2.0.0 adds support for the parsers babel (i. e. JavaScript) and babel-ts which are only available since Prettier v2 (and thus the peer dependency has received a major bump).
