The third release candidate for Zephyr 4.2.0 has been tagged:
https://github.com/zephyrproject-rtos/zephyr/releases/tag/v4.2.0-rc3
The merge window for features and enhancements remains closed until 4.2.0 is released.

We continue in the stabilization phase, and only blocker bug-fixes and documentation patches may be merged to the main branch. As a reminder to maintainers- please send PRs to update the release notes and migration guide for any areas you manage.

You may continue to submit pull requests for new features to gather feedback early or collaborate with others, but the release team would like to encourage everyone to focus on testing, fixing any blocker bugs found, and finalizing release notes.

Other bugs which are not critical enough to be categorized as blocker, but should still be part of 4.2 should be marked with the backport v4.2-branch label so they can be considered for the first dot release.
