About this tag
The release merge window tag covers discussion of Linux kernel development during the period when changes are gathered ahead of a release candidate. Current coverage focuses on Linux 7.2 and its June 2026 merge window, including the report that the kernel source tree reached 43,898,743 lines before the expected 7.2-rc1 release.

Readers can use this tag to follow how merge-window activity reflects the growing complexity of modern operating system development.
