Peer-Id and User-Agent

Peer-Id

From version 0.80 onward, Transmission's peer-id is formatted Azureus style with one digit for the major version, two digits for the minor version, and one character to denote a stable release (0), nightly build (Z), or prerelease beta (X). For example:

• -TR130X- Beta release leading up to version 1.30
• -TR1320- Official 1.32 release
• -TR132Z- Nightly build between 1.32 and 1.33

User-Agent

Its User-Agent header follows a similar format, plus the SVN revision in parenthesis:

• Transmission/1.30X (6416) Beta release leading up to version 1.30
• Transmission/1.32 (6455) Official 1.32 release
• Transmission/1.32+ (6499) Nightly build between 1.32 and 1.33

Before 0.80, versions of Transmission used two digits for the major version and two for the minor. For example, -TR0072- was Transmission 0.72.
