@meisterT Should we mention in the release notes that upcoming Release 3.4 includes new java_tools release 9.0 with major Error Prone version upgrade to 2.4.0, with a lot of fixes and out of the box support for Java 14?

And also warn, that some new EP checks were added and some existing checks were extended so that more diagnostic could be reported for new and existing EP checks so that Bazel users may see new compiler warnings or even failures with upcoming Bazel release 3.4?

FTR: I uploaded this PR https://github.com/bazelbuild/bazel/pull/11447 to add --incompatible_use_java_tools_beta_release option to make the java_tools upgrade process less disruptive, but it wasn't merged yet. So may be next time java_tools upgrade process will be less painful.

You can download the most recent release candidate here:
https://releases.bazel.build/3.4.0/rc2/index.html

Another way to test releases is to use Bazelisk (https://github.com/bazelbuild/bazelisk) and set the environment variable USE_BAZEL_VERSION to last_rc (see more https://github.com/bazelbuild/bazelisk#how-does-bazelisk-know-which-bazel-version-to-run).

~@meisterT - Do you know when is the next release and who's the owner of it?~

edit: Just saw the post by @philwo . Release 3.5 should be released this month.

I want to make sure that https://github.com/bazelbuild/bazel/commit/003f7664c91f4fec81e7607c0b59651915836d3a enters.

Thanks!

[meisterT]

I have just created https://github.com/bazelbuild/bazel/issues/11885 for the next release. @aiuto agreed to shepherd it.

[aiuto]

I will probably cut the baseline on August 5, so it will be in it.
