+^^^^^^^^^^^^

+- 2017-08-12
+
+
+New Features
+^^^^^^^^^^^^
+
+
+
+General
+^^^^^^^
+
+- Off cycle Minor release to fix SCM vulnerabilities.
+
+
+Security
+^^^^^^^^
+
+- security(critical): Bumped GIT to 2.9.5 fixes CVE-2017-1000117
+  https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1466490.html
+- security(critical): Bumped SVN to 1.9.7 fixes CVE-2017-9800
+  https://subversion.apache.org/security/CVE-2017-9800-advisory.txt
+- security(critical): Bumped Mercurial to 4.2.3 fixes  CVE-2017-1000116
+  https://www.mercurial-scm.org/wiki/WhatsNew#Mercurial_4.3_.282017-08-10.29
+
+
+Performance
+^^^^^^^^^^^
+
+- Fixed Mercurial Stream support for very large repositories. Due to discovered
+  bug in WebOb library we manage to fix Mercurial stream support.
+  Now cloning very large repos e.g 100GB, ~1mln commits should be much
+  faster, and use less memory.
+
+
+Fixes
+^^^^^
+
+- Fixed problem with default-reviewers in EE package that was missing panel
+  title and in some occasions generate 500 errors.
+- Fixed problem with potential URL generation inside our integration.
+  This was introduced during pyramid porting. We know ensure that proper
+  routing generation is done on all events.
+
+
+Upgrade notes
+^^^^^^^^^^^^^
+
+
+- The 4.9.0 release is an off-cycle release. Due to the fact that we needed to
+  bump Mercurial from 4.1.X to 4.2.X, and Subversion from 1.9.4 to 1.9.7, we
+  released this version not as 4.8.1 security bug fix but 4.9.0.
+  We know historically that SVN and Mercurial can have internal api changes.
+  We tested basic functionality for all 3 vcs-es but due to very short release
+  time we were unable to test everything. Please report any found problems to us
+  and we'll for sure address them.
+
+  Note to SVN users: Please make sure to upgrade mod_dav to 1.9.7 version.
+  At this time we know Wandisco provides 1.9.7 packages for most major distros.
