The 2.10 series release notes contain important changes in this release series.

Security Fixes

• Packages have been updated to their latest security versions.
• LOW: OAuth application access tokens and personal access tokens weren't sanitized from support bundles.

Bug Fixes

• The authentication graphs in the management console could be inaccurate and not display a legend due to incorrectly grouped and ordered keys.
• Authentication and application request/response graphs in the management console could fail to render when high availability replication was configured. The bug did not affect forwarding metrics to an external collectd server.
• /setup/replication in the management console returned a '500 Internal Server Error' when replication was configured.
• collectd metric paths could be truncated, which caused multiple write attempts to the same file for different metrics.
• Password reset emails incorrectly displayed reset links were valid for 24 hours when they are only valid for three hours.
• Pre-receive hooks were incorrectly triggered on internal reference updates.
• Pre-receive hooks could not be updated after moving to a new GitHub Enterprise instance, for example after failing over to a replica.
• Fetches or pushes that transferred more than 2 GB of data were incorrectly recorded as much larger in the logs for the Git proxy service, babeld.
• Users could receive a temporary "bad pack header" error when fetching a very large repository if the repository was being repacked at the same time.
• Suspended users could be assigned to issues.
• Users could delete organizations that contained repositories even if they were not permitted to delete repositories.
• Webhooks could send outdated data after editing an issue comment or changing the base branch of a pull request.
• Webhook requests incorrectly ignored local search domains when resolving hosts, which could result in "Couldn't resolve host name" errors.

Changes

• When authenticating via SAML the NameID will be recorded instead of the custom username attribute value when a custom username attribute is defined.
• The ghe-support-bundle command now honors the http_proxy environment variable.
• The value of the X-Forwarded-For header will now be recorded in the HAproxy log.
• The maximum number of HTTPS and websocket connections has been increased.

Known Issues

• We incorrectly redirect to the dashboard if you accessed GitHub Enterprise using an alias while in private mode. This might happen if you set a fully qualified domain name but the subdomain resolves correctly.
• Images uploaded to issues save with an absolute URL, so they can be broken if the hostname changes.
• On a freshly set up GitHub Enterprise without any users, an attacker could create the first admin user.
• Custom firewall rules aren't maintained during an upgrade.
• Enqueued background jobs are sometimes not purged when a repository is deleted.
• svn checkout may timeout while the repository data cache is being built. In most cases, subsequent svn checkout attempts will succeed.
• Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.
• GitHub Enterprise clustering can not be configured without https.
• Deleting a search index doesn't delete all associated metadata, which are then incorrectly reused if a new search index is created. This causes search index repair jobs to be reported as finished in the site admin when they were not.
• Background jobs are added to the "toggle_hidden_user_in_notifications" queue, but these jobs aren't processed on GitHub Enterprise. The entries are harmless but will show in ghe-resque-info output and in management console graphs. (updated 2017-07-13)
• Webhook requests incorrectly ignore local search domains when resolving hosts, which can result in "Couldn't resolve host name" errors. (updated 2017-07-14)
• Creating a support bundle fails with a “File exists” error if HAProxy logs have been rotated. (updated 2017-07-24)
• Using ghe-migrator, protected branch settings are always migrating with push restrictions enabled. (updated 2017-08-01)
• After changing the visibility of a repository, wiki search results have a conflicting number of displayed search results. Administrators can reindex the wiki through the site admin dashboard. (updated 2017-11-09)
• The create team API endpoint returns a 500 error if LDAP Sync is enabled and the team already exists. (updated 2018-01-09)
• Pull request reviewer usernames were not updated if a reviewer was mapped to a different username when migrating repositories using ghe-migrator. (updated 2018-04-12)

Errata

• We didn't include the fix for webhook requests incorrectly ignoring local search domains when resolving hosts in this release.

Thanks!
