What's changed

Fun stuff 🎉

• This release introduces a much improved merge and pull algorithm. The experience is similar to update or upgrade - if there are conflicts (or if the result doesn't typecheck), you are given a scratch file to get compiling. This is very new; let us know you run into any issues!
• The new upgrade.commit command will merge and remove the temporary branch created during an upgrade that required manual intervention. An analogous merge.commit will be in an upcoming release.
• A new lib.install command replaces the use of pull for installing libraries. Usage: lib.install @unison/base/releases/latest and use help lib.install for details.

Important deprecations 🪦

• UCM can no longer push or pull the old Git-based Unison codebases. Use UCM 0.5.20 or earlier to migrate them to Unison Share!

Lovely bugfixes 🐞

• A bug was causing delete.namespace to sometimes remove the last names for things without any warning. (4988)
• A bug was causing some commands to work off of an out-of-date namespace. (5027)
• find followed by docs <n> would fail. (5012)
• dependents followed by delete <n> would fail. (5019)
• UCM would just complain if a scratch file it wanted to write to didn't exist. (4973)
• auth.login was invisible in help. (5028)
• The ui command couldn't find its data files when using the ucm launcher script included in manual installs. (5048)/(5050)
• A bug caused hashes to be displayed in the LSP diagnostics. (#4960)
• LSP diagnostics were one change behind. (4957)
• The JIT version of zlib.compress on a >64k buffer. (4961)
