Key highlights include asynchronous file saves to eliminate UI freezes, improved WSL/Docker project responsiveness, faster Spring Boot configuration metadata loading, and extensive Spring ecosystem improvements (Security, Cache, Events, Thymeleaf). Kotlin support gains automatic kapt configuration for Lombok, better Java code completion for Kotlin members, and full removal of the legacy K1 mode. Editor improvements include Markdown footnote support, bookmark preservation across Git branch switches, and persistent Search Everywhere scope selection. The ML Code Completion ranking plugin is deprecated, and Task Management/Time Tracking plugins are unbundled from the default distribution. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What changed with the Machine Learning Code Completion plugin in IntelliJ IDEA 2026.2? The Machine Learning Code Completion (Ranking) plugin is deprecated and no longer bundled by default with IntelliJ IDEA 2026.2, because AI completion, next edit suggestions, and coding agents have largely replaced the benefits of ML-based ranking. It remains installable separately from JetBrains Marketplace for anyone who still wants it. _Track IDE plugin deprecations like this one on daily.dev before they disrupt your setup._ ### Why does editor file saving feel less laggy in IntelliJ IDEA 2026.2? File saves are now asynchronous, so writing a file to disk no longer blocks the UI thread, reducing freezes during save operations. Plugin authors need to review migration guidance since this changes how async VFS content writes work under the hood. _Developers upgrading their IDE tooling keep an eye on changes like this via daily.dev._ ### Is K1 mode still available in IntelliJ IDEA or Android Studio? No, K1-mode options and related code have been removed entirely from IntelliJ IDEA 2026.2 and Android Studio, since K2 adoption now exceeds 99% across both products. Developers relying on K1-specific settings should switch to K2 before upgrading. _Kotlin developers planning an upgrade path can follow changes like this on daily.dev._ ## Similar posts on daily.dev - [What's New in IntelliJ IDEA 2026.2](https://daily.dev/posts/what-s-new-in-intellij-idea-2026-2-sz6dkbk3z) · JetBrains · 10 upvotes · 0 comments - [IntelliJ IDEA 2026.2.2 Is Out\!](https://daily.dev/posts/intellij-idea-2026-2-2-is-out--mf7qkwdti) · JetBrains · 14 upvotes · 2 comments - [IntelliJ IDEA 2026.2 EAP Is Open](https://daily.dev/posts/intellij-idea-2026-2-eap-is-open-1mrjyeggc) · JetBrains · 5 upvotes · 1 comments --- Tags: [#devtools](https://daily.dev/tags/devtools), [#java](https://daily.dev/tags/java), [#kotlin](https://daily.dev/tags/kotlin), [#spring-boot](https://daily.dev/tags/spring-boot), [#jetbrains](https://daily.dev/tags/jetbrains) [View this post on daily.dev](https://daily.dev/posts/what-s-fixed-in-intellij-idea-2026-2-t8c2oe8a5) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"What’s fixed in IntelliJ IDEA 2026.2","url":"https://daily.dev/posts/what-s-fixed-in-intellij-idea-2026-2-t8c2oe8a5","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/what-s-fixed-in-intellij-idea-2026-2-t8c2oe8a5"},"datePublished":"2026-07-16T16:53:01.714Z","dateModified":"2026-09-14T08:01:48.122Z","description":"IntelliJ IDEA 2026.2 ships with over 1,300 bug fixes and usability improvements, including 140 performance and freeze fixes.
