-
- 2008-10-14
- Renamed states.IN to states.IT to avoid name clash which IN macro
- defined in windef.h (alexey.pelykh@gmail.com)
-
- 2008-07-19
- Removed some duplicate code & debugging variable (charles@transmissionbt.com)
-
- 2008-05-28
- Made JSON_value structure ansi C compliant. This bug was report by
- trisk@acm.jhu.edu
-
- 2008-05-20
- Fixed bug reported by charles@transmissionbt.com where the switching
- from static to dynamic parse buffer did not copy the static parse
- buffer's content.
