Roundtable

• Possibly moving the 64 bit watershed (to 57) (Callek)

** Includes support for <56 to update to 57 (lzma/bz2 update mars)

• • Makes sense if the benefit is a faster update path
  • How many users will be <56 by first week of November?

How should we communicate (non-dot release) uplifts that will not make 57 beta 8?
