Build Number Ranges

Defining product compatibility by specifying plugin since-build and until-build ranges.

Use this reference of build number ranges to specify the correct since-build and until-build values in your plugin descriptor.

Setting the actual values in plugin.xml is managed by the patchPluginXml Gradle task, see .

Build Number Validity

Please note the following regarding values:

• Values must represent the actual build numbers. Any made-up numbers must not be used and such plugins will be rejected on JetBrains Marketplace. For example, 233.* is invalid for since-build; any of 999.*, 234.* (maximum is 233.*) and 223.9999 are invalid for until-build.
• Not specifying until-build means it will include all future builds. This includes future, yet unreleased versions and possibly new IDEs, which might impact compatibility later.
• To support all releases for a specific branch, use dot-star suffix (.* ) in until-build. For example, 232.* for all 2023.2.x releases.

Before publishing, the plugin must be checked using against the specified version range (and specified compatible products) to ensure binary compatibility. Any additional reported errors/warnings should also be fixed when possible.

Plugins hosted on JetBrains Marketplace are checked automatically. According to Approval Guidelines, incompatible plugin versions will be restricted by JetBrains if necessary.

Build Number Format

To denote a release, a multipart build number is used. It consists of the following parts:

• Product ID (IC for IDEA Community, IU for IDEA Ultimate, RM for RubyMine, PY for PyCharm, PS for PhpStorm, etc.)
• Branch number (223)
• Build number in the branch (9559)

Branch numbers are based on the YYYY.R IDE release version numbers. The branch number takes the last two digits of the year and the R release number. For example, 231 for 2023.1, 232 for 2023.2, and 233 for 2023.3.

The build number may have multiple components: IU-162.94.11, IU-162.94.11.256.42. This gives more flexibility for third-party plugins and IDE developers. Plugins may specify compatibility versions more precisely (for example, requiring a specific bugfix release); IDE vendors may have build numbers based on a specific IntelliJ Platform version and specify additional internal version (for example 256.42 in XX-162.94.11.256.42) to allow plugin developers for their IDE to specify compatibility.

Multipart build numbers can also be used in the since-build and until-build attributes of idea-version. Usually you should omit the product ID and use only the branch number and build number, for example:

<!-- 2021.3, 2021.3.1, 2021.3.2, ... -->
<idea-version since-build="213" until-build="213.*"/>

<!-- 2021.3.3 or later -->
<idea-version since-build="213.7172.25"/>

Specific build numbers and their corresponding release version are available via Previous Releases on the corresponding product's download page, for example Previous IntelliJ IDEA Releases. For upcoming versions, see Early Access Program.

Targeting Multiple IDE Versions

{id="multipleIDEVersions"}

When supporting multiple major versions, it is strongly recommended to build against the lowest supported version to guarantee backwards-compatibility. In the case of supporting a range of platform versions with different underlying Java level (see below), it is required.

discusses tooling support to ensure compatibility with the chosen version range and IDEs.

Consult Incompatible API Changes and Notable API Changes for an overview of known breaking and relevant changes across IDE versions.

In some cases, keeping a dedicated branch and corresponding plugin release for each major IDE version might be required due to incompatibilities that cannot be solved in other ways.

Platform Versions

{id="platformVersions"}

Note that there is no YY0. In the YYYY.R versioning scheme, the R part starts at 1.
