Version release channels in Rust

Via rustup you may install Rust from different release channels. Rust releases follow a release train schedule. Meaning that all developments are done on the masterbranch and versions are released periodically on a tight schedule, instead of based on a certain feature set that makes up a version.

Rust uses three different release channels:

• nightly: an automated daily release.
• beta: every six weeks the changes from the master branch are taken and released to the beta channel.
• stable: another six weeks after the beta release was created those changes are merged to the stable channel.
