Release

v1.1.0-alpha.4 pre-release enhances a few features and cleans up a number of issues identified since alpha.3 while greatly expanding test coverage.

This is expected to be the final pre-release before a spec freeze in one week. To that end, there was much deep review and enhanced testing. This should be the last, large Altair release diff.

Make sure you note the new fork transition spec test type (#2363) that tests a series of block transitions across the fork boundary. Shoutout to @ralexstokes for putting that together!

On the R&D front, much refinement continues in the Merge and Sharding specs. Merge is increasingly stable and tested with a few known items left to tackle, while the Sharding spec is still in heavy refinement (thanks to all the sharding implementers for the many spec fixes and enhancements!).
