This post outlines the Long Term Support (or LTS for short) plan for current and upcoming releases:
v2.6.x is scheduled to be released soon and will be the last version to support iOS 14.0–14.7.
v2.7.0 will support iOS 15.0 and later only.
If any critical fixes are required for iOS 14.x support, they will be released in the 2.6.x pipeline.
v2.6.x is scheduled to be released soon ad will be the last version to support macOS 11.0 (Big Sur).
v2.7.0 will support macOS 12.0 and later only.
If any critical fixes are required for macOS 11.x support, they will be released in the 2.6.x pipeline.
The v2.6.x pipeline will continue to receive critical fixes, if any are necessary, for up to 6 months after v2.6.0 is released. After that date, no critical fixes will be issued and LTS support will end for those releases.
Hopefully with the release of v2.7.0, the LTS support will span for longer durations considering more features being supported now in iOS 15 and macOS 12.
