As discussed at the December OpenZFS Leadership Meeting[1], we would like to make sure that all stakeholders are informed of important proposed changes, regardless of what platform they originate on (Linux, illumos, FreeBSD, etc). This will help us get input from the best experts at code review time. "Important" changes include: - adding (or removing!) a new user-visible feature, no matter how small (e.g. adding a new CLI flag) - changing the user-visible behavior of existing features (e.g. now X will automatically do Y for you) - changing the on-disk format (e.g. to improve performance) - changing the zfs send stream format As a rule of thumb, if you are changing a manpage (other than to clarify existing functionality), it's probably an "important" change. The notification will occur via email to the developer@open-zfs.org mailing list, so please join that list if you'd like to be informed about upcoming important changes to OpenZFS. If you have feedback on these changes, please let the author know within 7 days. This guideline applies to newly-proposed changes, not retroactively to open PR's. However, here are some examples of open PR's that would be classified as "important": https://github.com/openzfs/openzfs/pull/690 ("zfs allow" can take numeric id) https://github.com/openzfs/openzfs/pull/664 (new kstats) https://github.com/openzfs/openzfs/pull/668 (SIGINT/SIGKILL can cancel channel program) https://github.com/openzfs/openzfs/pull/649 (add new functions to channel programs) https://github.com/openzfs/openzfs/pull/638 ("zfs send" handles SIGINFO) https://github.com/zfsonlinux/zfs/pull/8238 (remove new subcommand) https://github.com/zfsonlinux/zfs/pull/8044 (new compression algorithm) https://github.com/zfsonlinux/zfs/pull/8255 (new property, subcommand) https://github.com/zfsonlinux/zfs/pull/7958 (new on-disk format, send stream format, subcommand) --matt [1] https://docs.google.com/document/d/1w2jv2XVYFmBVvG1EGf-9A5HBVsjAYoLIFZAnWHhV-BM/edit
