brz 3.0.0

Codename:Pelican
3.0.1:NOT RELEASED YET

External Compatibility Breaks

  • The bzr command has been renamed to brz, to prevent clashes with upstream Bazaar. (Martin Packman, Jelmer Vernooij)
  • The –prefix/-p argument for bzr diff now defaults to -p1 rather than -p0. (Jelmer Vernooij, #1695126)
  • The brz register-branch command from the Launchpad plugin has been removed, because it has not worked for at least five years: it relies on password authentication rather than SSO, the relevant systems no longer have firewall-level access to the outside world, and in general the Mirrored branch type is deprecated. Either just push the branch to Launchpad or use code imports instead (https://help.launchpad.net/VcsImports). (Colin Watson, #254567, #483689)
  • brz no longer supports building the C extensions using Pyrex. Only Cython is supported. (Jelmer Vernooij)
  • Support for HTTP support using “pycurl” and the associated URL schemes “http+pycurl://” and “https+pycurl://” has been dropped. (Jelmer Vernooij, #82086, #377389, #122258, #516222, #545776, #1696602)
  • Support for medusa for FTP tests has been dropped, only pyftpdlib is now supported. (Jelmer Vernooij)
  • The deprecated brz get and brz clone commands have been removed. (Jelmer Vernooij)
  • The setting to ignore missing C extensions has been changed from ignore_missing_extensions=True to suppress_warnings=missing_extensions. (Jelmer Vernooij)
  • Remove format names as options to brz init and brz init-repository.. Now you must use brz init --format=.... This simplifies brz init --help. (Neil Martinsen-Burrell, #330494)
  • python-gpg is now used for checking GPG signatures rather than python-gpgme. (Jelmer Vernooij, #1702308)
  • python-gpg is now used for signing commits, rather than shelling out to the gnupg command. The gpg_signing_command option has been removed. (Jelmer Vernooij, #847388)
