We've + decided to use an odd micro version number (eg. 0.9.1) to indicate + in-progress development between releases. As soon as 0.9.2 is + tagged, the version will be incremented in CVS to 0.9.3 where it + will stay until just before 0.9.4 is built, uploaded, and tagged. + + So, even-micro == a released version, odd-micro == something in-between. + +Libpixman dependency dropped +---------------------------- + * As of this release, the dependency on an internal libpixman has + been dropped. Instead, the code from libpixman needed for cairo has + been incorporated into the cairo source tree. The motivation for + this change is that while cairo's API is stable and ready to be + maintained after the 1.0 release, libpixman's API is not, so we do + not want to expose it at this time. + + Also, the incorporation of libpixman into cairo also renames all + previously-public libpixman symbols in order to avoid any conflict + with a future release of libpixman + +API additions +------------- + * Macros and functions have been added so that the version of cairo + can be queried at either compile-time or at run-time. The version + is made available as both a human-readable string and as a single + integer: + + CAIRO_VERSION_STRING eg. "0.9.2" + CAIRO_VERSION eg. 000902 + + const char* + cairo_version_string (void); /* eg. "0.9.2" */ + + int + cairo_version (void); /* eg. 000902 */ + + A macro is provided to convert a three-part component version into + the encoded single-integer form: + + CAIRO_VERSION_ENCODE(X,Y,Z) + + For example, the CAIRO_VERSION value of 000902 is obtained as + CAIRO_VERSION_ENCODE(0,9,2). The intent is to make version + comparisons easy, either at compile-time: + + #if CAIRO_VERSION >= CAIRO_VERSION_ENCODE(0,9,2) + ... + #endif + + Or at run-time: + + if (cairo_version() >= CAIRO_VERSION_ENCODE(0,9,2)) { /* ... */ } + +Thread safety +------------- + * This release adds pthread-based locking (when available) to make + the caches used by cairo safe for threaded programs. Some may + remember a failed experiment with this locking between the 0.5.1 + and 0.5.2 snapshots, (where even single-threaded programs that + linked with -lpthread would deadlock). We believe that that problem + has been fixed, so we are looking forward to testing and reports + from users with threaded applications. + +Bug fixes +--------- + * The XCB and Quartz backends failed to compiled in the 0.9.0 release + due to minor syntax errors. These have now been fixed. + + * Various crashes in glitz and pixman due to size 0 glyphs have been + fixed. + Release 0.9.0 (2005-08-08 Carl Worth <cworth@cworth.org>) ========================================================= Soname change @@ -17,7 +93,7 @@ Soname change release series have distinct library versioning.
