Let's start with how versioning used to be done. - - Historical versioning in Cygwin 16.0 to 19.5: - - In the olden days of Cygwin, we had a dll major and minor version - and a registry version. The major number started at 16 because the - "b15" GNU-Win32 release of the compiler tools was out when this - scheme was started. We incremented the DLL name frequently (for - every official release) and towards the end of this period every - release used a different shared memory area to prevent DLLs from - interfering with each other (embedding a build timestamp into the - name of the shared memory area). This turned out to be a Bad Idea - (tm) because people needed to mingle separate releases and have - them work together more than we thought they would. This was - especially problematic when tty info needed to be retained when an - old Cygwin executable executed a newer one. - - In the old scheme, we incremented the major number whenever a - change to the dll invalidated existing executables. This can - happen for a number of reasons, including when functions are - removed from the export list of the dll. The minor number was - incremented when a change was made that we wanted to record, but - that didn't invalidate existing executables. Both numbers were - recorded in the executable and in the dll. - - In October 1998 (starting with Cygwin 19.6), we started a new - means of Cygwin versioning: */ - - /* The DLL major and minor numbers correspond to the "version of - the Cygwin library".
