See + doc/troubleshooting.rst for details. + +* A new log files system was added. See the multimailhook.logFile, + multimailhook.errorLogFile and multimailhook.debugLogFile variables. + +* git_multimail.py can now be made more verbose using + multimailhook.verbose. + +* A new option --check-ref-filter is now available to help debugging + the refFilter* options. + +Formatting emails +----------------- + +* Formatting of emails was made slightly more compact, to reduce the + odds of having long subject lines truncated or wrapped in short list + of commits. + +* multimailhook.emailPrefix may now use the '%(repo_shortname)s' + placeholder for the repository's short name. + +* A new option multimailhook.subjectMaxLength is available to truncate + overly long subject lines. + +Bug fixes and minor changes +--------------------------- + +* Options refFilterDoSendRegex and refFilterDontSendRegex were + essentially broken. They should work now. + +* The behavior when both refFilter{Do,Dont}SendRegex and + refFilter{Exclusion,Inclusion}Regex are set have been slightly + changed. Exclusion/Inclusion is now strictly stronger than + DoSend/DontSend. + +* The management of precedence when a setting can be computed in + multiple ways has been considerably refactored and modified. + multimailhook.from and multimailhook.reponame now have precedence + over the environment-specific settings ($GL_REPO/$GL_USER for + gitolite, --stash-user/repo for Stash, --submitter/--project for + Gerrit). + +* The coverage of the testsuite has been considerably improved. All + configuration variables now appear at least once in the testsuite. + +This version was tested with Python 2.6 to 3.5.

See an example in + post-receive.example. + +* Error handling for SMTP has been improved (we used to print Python + backtraces for legitimate errors). + +* The SMTP mailer can now check TLS certificates when the newly added + configuration variable multimailhook.smtpCACerts. + +* Python 3 portability has been improved. + +* The documentation's formatting has been improved. + +* The testsuite has been improved (we now use pyflakes to check for + errors in the code). + +This version has been tested with Python 2.4 and 2.6 to 3.5, and Git +v1.7.10-406-gdc801e7, 2.1.4 and 2.8.1.339.g3ad15fd. + +No change since 1.3 RC1. + +Release 1.2.0 +============= + +* It is now possible to exclude some refs (e.g. exclude some branches + or tags). See refFilterDoSendRegex, refFilterDontSendRegex, + refFilterInclusionRegex and refFilterExclusionRegex. + +* New commitEmailFormat option which can be set to "html" to generate + simple colorized diffs using HTML for the commit emails. + +* git-multimail can now be ran as a Gerrit ref-updated hook, or from + Atlassian BitBucket Server (formerly known as Atlassian Stash). + +* The From: field is now more customizeable. It can be set + independently for refchange emails and commit emails (see + fromCommit, fromRefChange). The special values pusher and author can + be used in these configuration variable. + +* A new command-line option, --version, was added. The version is also + available in the X-Git-Multimail-Version header of sent emails. + +* Set X-Git-NotificationType header to differentiate the various types + of notifications. Current values are: diff, ref_changed_plus_diff, + ref_changed. + +* Preliminary support for Python 3. The testsuite passes with Python 3, + but it has not received as much testing as the Python 2 version yet. + +* Several encoding-related fixes. UTF-8 characters work in more + situations (but non-ascii characters in email address are still not + supported). + +* The testsuite and its documentation has been greatly improved. + +Plus all the bugfixes from version 1.1.1. + +This version has been tested with Python 2.4 and 2.6 to 3.5, and Git +v1.7.10-406-gdc801e7, git-1.8.2.3 and 2.6.0.
