 releaseNotes: >-
-  This release fixes a guard page bounds check that would usually present
-  as a ship crashing with loom: bogus ward. This bug (present since
-  vere-v2.7) also has a small chance of corrupting persistent state, so we
-  encourage users to upgrade as soon as possible.
-  
-  The release also fixes a bug with the meld command that was causing it
-  to run twice for every invocation.
