 Release Date
 ^^^^^^^^^^^^
 
 - 2016-12-02
 
 
 New Features
 ^^^^^^^^^^^^
 
 - Diffs: re-implemented diff engine. Added: Syntax highlighting inside diffs,
   new side-by-side view with commenting and live chat. Enabled soft-wrapping of
   long lines and much improved rendering speed for large diffs.
 - File source view: new file display engine. File view now
   soft wraps long lines. Double click inside file view show occurrences of
   clicked item. Added pygments-markdown-lexer for highlighting markdown syntax.
 - Files annotation: Added new grouped annotations. Color all related commits
   by double clicking singe commit in annotation view.
 - Pull request reviewers (EE only): added new default reviewers functionality.
   Allows picking users or user groups defined as reviewers for new pull request.
   Picking reviewers can be based on branch name, changed file name patterns or
   original author of changed source code. eg *.css -> design team.
   Master branch -> repo owner, fixes #1131.
 - Pull request reviewers: store and show reasons why given person is a reviewer.
   Manually adding reviewers after creating a PR will now be also indicated
   together with who added a given person to review.
 - Integrations: Webhooks integration now allows to use variables inside the
   call URL. Currently supported variables are ${repo_name}, ${repo_type},
   ${repo_id}, ${repo_url}, ${branch}, ${commit_id}, ${pull_request_id},
   ${pull_request_url}. Commits are now grouped by branches as well.
   Allows much easier integration with CI systems.
 - Integrations (EE only): allow wildcard * project key in Jira integration
   settings to allow referencing multiple projects per commit, fixes #4267.
 - Live notifications: RhodeCode sends live notification to online
   users on certain events and pages. Currently this works on: invite to chat,
   update pull request, commit/inline comment. Part of live code review system.
   Allows users to update the reviewed code while doing the review and never
   miss any updates or comment replies as they happen. Requires channelstream
   to be enabled.
 - Repository groups: added default personal repository groups. Personal groups
   are isolated playground for users allowing them to create projects or forks.
   Adds new setting to automatically create personal repo groups for newly
   created users. New groups are created from specified pattern, for example
   /u/{username}. Implements #4003.
 - Security: It's now possible to disable password reset functionality.
   This is useful for cases when users only use LDAP or similar types of
   authentication. Implements #3944
 - Pull requests: exposed shadow repositories to end users. Users are now given
   access to the shadow repository which represents state after merge performed.
   In this way users or especially CI servers can much easier perform code
   analysis of the final merged code.
 - Pull requests: My account > pull request page now uses datagrid.
   It's faster, filterable and sortable. Fixes #4297.
 - Pull requests: delete pull request action was moved from my account
   into pull request view itself. This is where everyone was looking for it.
 - Pull requests: improve showing failed merges with proper status in pull
   request page.
 - User groups: overhaul of edit user group page. Added new selector for
   adding new user group members.
 - Licensing (EE only): exposed unlock link to deactivate users that are over
   license limit, to unlock full functionality. This might happen when migrating
   from CE into EE, and your license supports less active users then allowed.
 - Global settings: add a new header/footer template to allow flash filtering.
   In case a license warning appears and admin wants to hide it for some time.
   The new template can be used to do this.
 - System info: added create snapshot button to easily generate system state
   report. Comes in handy for support and reporting. System state holds
   information such as free disk/memory, CPU load and some of RhodeCode settings.
 - System info: fetch and show vcs settings from vcsserver. Fixes #4276.
 - System info: use real memory usage based on new psutil api available.
 - System info: added info about temporary storage.
 - System info: expose inode limits and usage. Fixes #4282.
 - Ui: added new icon for merge commit.
 
 
 
 General
 ^^^^^^^
 
 - Notifications: move all notifications into polymer for consistency.
   Fixes #4201.
 - Live chat (EE): Improved UI for live-chat. Use Codemirror editor as
   input for text box.
 - Api: WARNING DEPRECATION, refactor repository group schemas. Fixes #4133.
   When using create_repo, create_repo_group, update_repo, update_repo_group
   the *_name parameter now takes full path including sub repository groups.
   This is the only way to add resource under another repository group.
   Furthermore giving non-existing path will no longer create the missing
   structure. This change makes the api more consistent, it better validates
   the errors in the data sent to given api call.
 - Pull requests: disable subrepo handling on pull requests. It means users can
   now use more types of repositories with subrepos to create pull requests.
   Since handling is disabled, repositories behind authentication, or outside
   of network can be used.
 - VCSServer: fetch backend info from vcsserver including git/hg/svn versions
   and connection information.
 - Svn support: it's no longer required to put in repo root path to
   generate mod-dav-svn config. Fixes #4203.
 - Svn support: Add reload command option (svn.proxy.reload_cmd) to ini files.
   Apache can now be automatically reloaded when the mod_dav_svn config changes.
 - Svn support: Add a view to trigger the (re)generation of Apache mod_dav_svn
   configuration file. Users are able to generate such file manually by clicking
   that button.
 - Dependency: updated subversion library to 1.9.
 - Dependency: updated ipython to 5.1.0.
 - Dependency: updated psutil to 4.3.1.
 
 
 Security
 ^^^^^^^^
 
 - Hipchat: escape user entered data to avoid xss/formatting problems.
 - VCSServer: obfuscate credentials added into remote url during remote
   repository creation. Prevents leaking of those credentials inside
   RhodeCode logs.
 
 
 Performance
 ^^^^^^^^^^^
 
 - Diffs: new diff engine is much smarter when it comes to showing huge diffs.
   The rendering speed should be much improved in such cases, however showing
   full diff is still supported.
 - VCS backends: when using a repo object from database, re-use this information
   instead of trying to detect a backend. Reduces the traffic to vcsserver.
 - Pull requests: Add a column to hold the last merge revision. This will skip
   heavy recalculation of merge state if nothing changed inside a pull request.
 - File source view: don't load the file if it is over the size limit since it
   won't be displayed anyway. This increases speed of loading the page when a
   file is above cut-off limit defined.
 
 
 Fixes
 ^^^^^
 
 - Users admin: fixed search filter in user admin page.
 - Autocomplete: improve the lookup of users with non-ascii characters. In case
   of unicode email the previous method could generate wrong data, and
   make search not show up such users.
 - Svn: added request header downgrade for COPY command to work on
   https setup. Fixes #4307.
 - Svn: add handling of renamed files inside our generated changes metadata.
   Fixes #4258.
 - Pull requests: fixed problem with creating pull requests on empty repositories.
 - Events: use branch from previous commit for repo push event commits data so
   that per-branch grouping works. Fixes #4233.
 - Login: make sure recaptcha data is always validated. Fixes #4279.
 - Vcs: Use commit date as modification time when creating archives.
   Fixes problem with unstable hashes for archives. Fixes #4247.
 - Issue trackers: fixed bug where saving empty issue tracker via form was
   causing exception. Fixes #4278.
 - Styling: fixed gravatar size for pull request reviewers.
 - Ldap: fixed email extraction typo. An empty email from LDAP server will now
   not overwrite the stored one.
 - Integrations: use consistent formatting of users data in Slack integration.
 - Meta-tags: meta tags are not taken into account when truncating descriptions
-  that are too long. Fixes #4305.
  No newline at end of file
+  that are too long. Fixes #4305.

+Upgrade notes
+^^^^^^^^^^^^^
+
+- Api: please adjust your scripts that uses any of create_repo,
+  create_repo_group, update_repo, update_repo_group. There's an important change
+  in how the repo_name/group_name parameters work. Please check the API docs
+  for latest information.
+
+- Installation: starting from 4.5.0 installer now changes the default mode to http.
+  If you were using the `self_managed_supervisor=True` flag inside
+  `.rccontrol.ini` to manually switch to that mode. This is no longer required
+  and we recommend removing that flag. Migration should already change that
+  however in case of any troubles with VCSServer after upgrade
+  please make sure `vcs.protocol=` is set to `http` and not `pyro4` inside
+  rhodecode.ini
+
+- New setting about password recovery was introduced. Please make sure to
+  adjust what ever default you want to have inside your instance. The default
+  is that password recovery is enabled.
