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 method of Cygwin versioning: */ /* The DLL major and minor numbers correspond to the "version of the Cygwin shared library". This version is used to track important changes to the DLL and is mainly informative in nature. */ #define CYGWIN_VERSION_DLL_MAJOR 1005 #define CYGWIN_VERSION_DLL_MINOR 9 /* Major numbers before CYGWIN_VERSION_DLL_EPOCH are incompatible. */ #define CYGWIN_VERSION_DLL_EPOCH 19 /* CYGWIN_VERSION_DLL_COMBINED gives us a single number representing the combined DLL major and minor numbers. */ /* WATCH OUT FOR OCTAL!
