Long Term Support (LTS) releases only bug fixes to a particular, fixed set of features from the current LTS channel. As a result, each LTS channel tends to become more stable over time; read the release notes from the current channel to make sure you aren't missing any features you need.

If you can't regularly upgrade your machines, this may be the channel for you.

Periodically, we will update the set of features that we support with bug fixes and start a new LTS channel. This will not the change the set of features available to an existing or automatically-updated installation of a LTS channel; you have to make the decision to change manually. However, after a time, we will stop issuing additional bug fixes for older LTS channels.
