Major change: DNS settings are no longer configured via the the Management Console, and any custom nameservers specified via the console will be lost after upgrading to 2.0.1.
When configured to use DHCP, GitHub Enterprise now relies on the DNS nameservers provided by the DHCP server. This is the default configuration for GitHub on AWS, and no changes are required when upgrading an EC2 instance.
If you are using DHCP on VMWare and your server does not provide nameservers, or if you need custom nameservers that are different from your DHCP lease, please add them to
/etc/resolvconf/resolv.conf.d/head after upgrading.
If you are using a static IP configuration, please reconfigure static network configuration after upgrading to 2.0.1, either via tty1 or
sudo ghe-setup-network -v.
Note: You may also choose to add custom nameservers to
/etc/resolvconf/resolv.conf.d/head before running
ghe-upgrade. These settings will be retained across the upgrade to 2.0.1 and future releases.
The 2.0.1 release ships with some known issues that we were unable to fix before release. If any of these will cause major problems for your organization, we recommending waiting for 2.1.0 or 2.0.2 before upgrading.
- News feed activity links point to the hostname and protocol used when they were generated (affects renamed hosts).
- "Test domain settings" will fail when a DNS server is invalid or not reachable.
ghe-restore should require that maintenance mode is enabled before restoring.

- We display the time in the scheduled maintenance banner in UTC instead of the viewer's timezone. (updated 2015-06-18)
- Images uploaded to issues save with an absolute URL, so they can be broken if the hostname changes. (updated 2015-07-14)
- With private mode enabled, a Pages site with no default page serves a generic error rather than an informative message. (updated 2015-07-14)
