What do the letters “d” and “b” stand for in MT-NewsWatcher version numbers?
“d” stands for “development”. “b” stands for “beta test”. For example, version 3.0b12 is “the 12th beta test version of MT-NewsWatcher 3.0”. In general, all development versions precede all beta versions. So, for example, version 3.0d17 is earlier than 3.0b15. Version 3.0 final has no letter, and is just plain “3.0”. All of the development and beta versions are earlier (older) than version 3.0 final. This is a standard version numbering convention in the Mac world, not something made up just for MT-NewsWatcher.
