Running this version of Mission Control for the first time will
automatically migrate your account data to a new location. If you
subsequently downgrade to an older version, it will no longer find your
account data. Taking a backup copy of ~/.mission-control before you
upgrade is recommended.

Configuration changes:

• Accounts are now stored in the telepathy/mission-control subdirectory
  of g_get_user_data_dir(). On Unix, this usually means
  ~/.local/share/telepathy/mission-control, but can be changed with the
  standard $XDG_DATA_HOME and $XDG_DATA_DIRS environment variables.

• ./configure --with-accounts-dir (at build time) and $MC_ACCOUNTS_DIR
  (at runtime) no longer change where new accounts are stored. They now
  set what Mission Control considers to be the "old" location for
  accounts; accounts in that directory will be moved into the new
  location. Using this option is deprecated.

Enhancements:

• Migrate accounts and avatars from ~/.mission-control to
  the location described above
  (fd.o #35896; W. Jon McCann, Jonny, Simon)
• More removals of obsolete code and interfaces (fd.o #54633, Simon)

Fixes:

• Recover from incomplete password migrations caused by upgrading to
  Empathy 3 while running MC 5.12.1 or older, by deleting the old (MC)
  copy of the password if Empathy has already copied it
  (fd.o #42088, Simon)
• Omit generated file mcp-signals-marshal.h from tarballs (Simon)
