re: Firefox 16 Adds Charms For Developers
"Also referred to as Firefox Aurora 16--the designation Mozilla applies to its beta channel releases..."
This isn't quite accurate. The current versions are as follows:
Nightly builds - the cutting edge, with code landing daily (least stable). Current version: 18
Aurora builds - may be considered "alpha" quality. Minimal testing. Current version: 17
Beta builds - more testing, more stable than Aurora, "pre-release". Current version: 16
Release builds - most stable, official release. Current version: 15
Before 15 was released earlier this week, 16 *was* Aurora. It has now moved up to the Beta channel.
