Last week, we announced a preview program for the new UI that we’re working on for IntelliJ-based IDEs. We’ve received an overwhelming number of comments, and we can’t reply to each one individually, so we’d like to address some of the most common concerns. Before announcing the preview program, we ran an extensive dogfooding program inside JetBrains as well as usability tests with external users. Overall, we got a very positive reception, and the initial feedback from the private preview program matches that. We do hear your concerns, however, and we want to emphasize that it’s not our goal

As you no doubt know, several major vulnerabilities have been recently discovered in the version 2 of the log4j library. As we have previously announced, the IDEs based on the IntelliJ Platform are not affected by this vulnerability, because they use a patched version of log4j 1.2 with all network-related code removed. Versions 1 and 2 of the log4j library are two completely different codebases with incompatible APIs, and migrating from one to the other is a non-trivial endeavor with unclear benefits. Despite that, some automated security tools still flag our use of an “old” version of log4j a

This is the second part of the roadmap of IntelliJ IDEA and IntelliJ-based IDEs for 2020. The first part of the roadmap was focused mostly on low-level features in the platform. In this post we’ll be talking about higher-level features, ones that the users will directly interact with. Some of these features will roll out in 2020.1, and others will appear in releases later during the year. Localization Last year, we localized the JetBrains Website and made it available in 8 different languages. Now we’re happy to announce that we’re working on localizing IntelliJ-based IDEs. We’re working on

We’d like to unveil some of our current efforts to improve IntelliJ IDEA and the other IDEs based on the IntelliJ Platform. The results of these efforts are going to be released over the next year, some as soon as in the 2020.1 release in the spring. They are centered around two main themes: performance and support for modern development workflows. Performance Indexing Performance Two of the main pain points related to the performance of our IDEs are startup performance (a tool that takes a long time to start is perceived as heavyweight) and indexing speed. We did a lot to speed up startup

Over the years, IntelliJ IDEA has accumulated support for a large array of technologies, and many of the technologies are no longer being actively maintained. We know that there are still people using these technologies, and up until now, we’ve been maintaining the plugins for them as part of the main IntelliJ IDEA source repository. However, our project has been growing, and carrying around this excess baggage is getting more and more difficult both for our users (as the plugins affect the size of the installation and potentially the performance of the IDE) and for our development team. At th

Today is a great day for the Kotlin community. KotlinConf, the inaugural Kotlin conference, opens today, and we're really impressed that around 1200 attendees from all over the world have joined us in San Francisco. During the conference keynote, Andrey Breslav, the lead designer of Kotlin, has announced a few major developments around Kotlin, and now we're sharing the news with everyone else. Kotlin 1.2 RC The first major announcement from the keynote is the release of Kotlin 1.2 Release Candidate. The new features in this release include the experimental support for multiplatform projects,
