- We use libtool CURRENT:REVISION:AGE versioning scheme. Quoting libtool
- documentation on how to handle the values:
-
- 1. Start with version information of `0:0:0' for each libtool library.
-
- 2. Update the version information only immediately before a public
- release of your software. More frequent updates are unnecessary,
- and only guarantee that the current interface number gets larger
- faster.
-
- 3. If the library source code has changed at all since the last
- update, then increment REVISION (`C:R:A' becomes `C:r+1:A').
-
- 4. If any interfaces have been added, removed, or changed since the
- last update, increment CURRENT, and set REVISION to 0.
-
- 5. If any interfaces have been added since the last public release,
- then increment AGE.
-
- 6. If any interfaces have been removed since the last public release,
- then set AGE to 0.
+ We use libtool CURRENT:REVISION:AGE versioning scheme. Here are the
+ rules for updating the values below, this should be done whenever wx
+ version (wx/version.h) changes (we abbreviate WX_CURRENT:REVISION:AGE
+ as C:R:A respectively):
+
+ 0. Set C:R:A = 0:0:0 if major or minor version has changed.
+
+ 1. If any API has been removed or otherwise changed in backwards
+ incompatible way, then change C:R:A to C+1:0:0
+
+ 2. Else, if any API has been added, change C:R:A to C+1:0:A+1
+
+ 3. Else, i.e. if there were no changes at all to API but only internal
+ changes, change C:R:A to C:R+1:A
