add more explaining, warnings and justifications on mySegment is special-cased to null in NULL_FILE (IDEA-CR-46034)

Java: Use 'enum' keyword for enums in quick doc. Don't show 'final' and 'static' in that case - JLS 8.9 (IDEA-175215)

PY-35103 Running "pycharm.bat" complains "cannot find VM options file" if the custom VM options file was created

[groovy] check if groovy file is inside sources before checking if `Field` identifier is in this file (IDEA-211117)

There are no indexes for files outside source roots and `#hasIdentifierInFile` always returns `false`.

It adds tools.jar unnecessarily; and it doesn't make sense in environments without full Groovy SDK (e.g. Maven).

When 'def' is used the return type is seen as Object from other files leading to unnecessary warnings in code.

build scripts: publish modules which required to build IntelliJ IDEA from sources as Maven artifacts (IDEA-194151)

Newly introduced 'intellij.tools.jps.buildScriptDependencies' module contains all dependencies which are required to invoke build scripts for IntelliJ-based IDEs.

The build scripts was updated to support generation of Maven artifacts from modules without sources. antlayout.jar was rebuilt from sources to include changes in JarContainer.

netty-codec-http2-4.1.34.Final.jar 407 KB

netty-codec-socks-4.1.34.Final.jar 119 KB
netty-handler-proxy-4.1.34.Final.jar 22 KB

This year TeamCity plugin will be migrated to REST API and opposite to Upsource will use http client that based on Netty (highly likely). But problem is that since 2018.2 IntelliJ Platform doesn't bundle netty proxy handler classes anymore. Now it is fixed (probably will be cherry-picked to 191).

It is tricky question should 3rd-party plugin bundle own plugin version or not, but in case of http client it is not only about reducing plugin download size and final class path, but about reusing resources (in case of netty - threads/buffers/so on).
