It comes just two days (and only one working day) after the 1.5.18 snapshot. The quick snapshot is due to two embarrassing bugs (both affecting cairo-xlib) that had been introduced in the 1.5.18 snapshot. The fixes for these are described below along with a few other fixes, (which hopefully aren't introducing new bugs this time). We're hopeful that this release candidate holds up better than the last one, and that we'll be able to make a 1.6.0 release soon with no major code changes from this snapshot. Have fun with cairo, everybody! -Carl Major changes from cairo 1.5.18 to cairo 1.5.20 =============================================== cairo-xlib ---------- Revert fix from 1.5.18 to allow pattern expansion based on the filter mode. This fix seemed so boring, (the use case it addresses is almost never used in practice), that it didn't even get mentioned in the 1.5.18 release notes. However, the "fix" happened to break rendering that is always used resulting in corrupt image rendering in mozilla, evolution, and probably everything else that uses cairo. Fix to avoid BadMatch errors in cairo_surface_create_similar. These were introduced, (inadvertently, of course), as part of the fix in 1.5.18 for creating similar surfaces without the Render extension. Again, thanks to mozilla, (and Vladimir Vukicevic in particular), for noticing our mistake. general ------- Correctly handle an in-error surface in cairo_surface_write_to_png. Previously this function would cause an assertion failure if you gave it a finished surface. Now it cleanly returns a CAIRO_STATUS_SURFACE_FINISHED result instead. Avoid potentially infinite wandering through memory inside _cairo_hull_prev_valid. Thanks to Jonathan Watt for noticing this problem: https://bugzilla.mozilla.org/show_bug.cgi?id=306649#c21 cairo-pdf --------- Fix generation of "soft" masks made by drawing to a similar surface and then calling cairo_mask_surface() with it. cairo-svg --------- Fix for code that uses cairo_mask() on an intermediate surface which is later passed to cairo_mask_surface().
