## Ubuntu U U Release Task Signup Sheet

This signup sheet is to be used for planning release milestone tasks.

The Alpha and Beta 1 milestones have been replaced with [Testing Weeks](https://lists.ubuntu.com/archives/ubuntu-release/2018-April/004434.html), which are organized ad hoc at this point.

When the archive is frozen, all members of the release team are expected to participate in bug fix reviews.

After [Feature Freeze](https://ubuntu.com/project/docs/release-team/freezes/#feature-freeze), all members of the release team are expected to participate in Feature Freeze Exception reviews in their particular area of expertise.

After [Final Beta](https://ubuntu.com/project/docs/release-team/release-cycle/#finalization), all members of the release team are expected to participate in Bug fix reviews in their particular area of expertise.
