Quality improvements in IntelliJ IDEA 2021.1

While developing IntelliJ IDEA 2021.1 we’ve spent more time than usual improving product quality. Even though the initial release contained a few unfortunate regressions that we’ve fixed in 2021.1.1, we’d like to share more details about quality-related work that went into v.2021.1.

We concentrated on three key areas: performance, elimination of freezes and exceptions, and regression handling.

In total, we closed over 1,500 YouTrack issues!

• We fixed more than 600 issues in the IntelliJ IDEA core functionality, and over 400 minor UI improvements. We were careful not to introduce any big changes that might break the habits you have formed.
• We implemented around 400 other fixes, including ones aimed at eliminating freezes and increasing performance in Java refactorings and code completion.
• For JetBrains Runtime (JBR), we resolved functionality issues in JCEF and crashes. Also, we rebased JBR on top of OpenJDK 11.0.10.
• We fixed over 150 issues in IntelliJ IDEA Ultimate, including performance optimizations for framework-specific features and diagrams. Some of the top prioritized fixed issues had to do with regression in Spring, JPA, Java EE, and other frameworks.
• We significantly improved the Kotlin plugin performance by speeding up error highlighting and code completion. At least a dozen different problems that led to IDE freezes were fixed, too.
• In Version Control, we addressed many minor issues in the Staging area support and Commit message handling. We also reworked the UI for creating GitHub pull requests, and we fixed various minor issues with GitHub reviews.

Bottomline

We hope this post brings more transparency about what we do. For IntelliJ IDEA, we prioritize bug fixing and we invest a lot of time in resolving the key issues to increase the product quality. And the fact our issue backlog got shorter after we released v2021.1 makes us happy, too!

Our team is energized to improve quality with each new release. Don’t forget to share all your concerns with us so we can address them going forward.

Happy developing!
