It +comes just less than 2 weeks after 1.4.0. We hadn't anticipated an +update this early, but we've managed to collect some important fixes +that we wanted to get out to cairo users as soon as possible, (6 fixes +for crashes, 1 case where graphical elements would not be drawn at +all, a handful of backend-specific bugs, and several important build +fixes). + +There's almost nothing but bug fixes in this release, (see below one +optimization that Behdad did sneak in), so we recommend that everyone +upgrade to this release when possible. + +Thanks to the many people that worked to fix these bugs, and those +that did the work to report them and to test the fixes, (wherever +possible both names are credited below). + +Critical fixes +-------------- +• Fix a crash due to a LOCK vs. UNLOCK typo (M. Drochner fixing Carl + Worth's embarrassing typo). + + http://bugs.freedesktop.org/show_bug.cgi?id=10235 + +• Fix potential buffer overflow, which on some systems with a checking + variant of snprintf would lead to a crash (Adrian Johnson, Stanislav + Brabec, and sangu). + + https://bugs.freedesktop.org/show_bug.cgi?id=10267 + https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=232576 + +• Fix a crash in cairo_stroke_extents or cairo_in_stroke when line + width is 0.0. (Carl Worth and Sebastien Bacher) + + https://bugs.freedesktop.org/show_bug.cgi?id=10231 + +• Fix a crash on certain combinations of X server/video drivers (Carl + Worth and Tomas Carnecky). + + https://bugs.freedesktop.org/show_bug.cgi?id=10250 + +• Fix a crash due to mishandling of invalid user input (Carl Worth and + Alexander Darovsky). + + https://bugs.freedesktop.org/show_bug.cgi?id=9844 + +• xlib: Cleanup server-side glyph caches on XCloseDisplay. This + eliminated a crash detected by the perf suite, (and that + applications could have run into as well). (Chris Wilson) + +Other bug fixes +--------------- +• Fix for some geometry which simply disappeared under some + transformations---a stroked line with an extreme skew in X, for + example (Carl Worth and Jonathan Watt). + + https://bugzilla.mozilla.org/show_bug.cgi?id=373632 + +• SVG: Fix radial gradients for CAIRO_EXTEND_REFLECT and when r0 > r1 + (Emmanuel Pacaud). + +• PDF: Set page group color space to DeviceRGB. + + This fixes incorrect (muddy) transparent colors when rendering cairo + PDF output in some viewers. (Adrian Johnson, Adam Goode, and + MenTaLguY). + + http://lists.freedesktop.org/archives/cairo/2006-November/008551.html + +• win32: Return correct metrics when hinting is off, and fix font + descent computation (Behdad Esfahbod). + +• quartz: Fix glyph interfaces to correctly return user-space rather + than device-space coordinates (Brian Ewins). + + https://bugs.freedesktop.org/show_bug.cgi?id=9568 + +• xcb: Fix parameter-order confusion with xcb_create_pixmap, which now + makes all tests that pass with xlib now pass with xcb (Carl Worth, + Jamey Sharp). + +• Fix some memory leaks in the perf suite (Chris Wilson). + +• Fix perf suite to consider changes in pixman/src (Mathias + Hasselmann). + +Build fixes +----------- +• Don't include pre-generated cairo-features.h file. This was causing + build failures when building with the directfb backend enabled + (Behdad Esfahbod). + + https://bugs.freedesktop.org/show_bug.cgi?id=10189 + +• Eliminate use of maintainer mode from cairo's automake/configure + script. This means that updates to files such as Makefile.am will + take effect, (by rerunning automake and friends as necessary) when + invoking make rather than being silently ignored. (Behdad Esfahbod) + +• Don't compile cairo-deflate-stream.c, which depends on zlib, unless + building the pdf backend which requires it. (Carl Worth, Tor + Lillqvist) + + https://bugs.freedesktop.org/show_bug.cgi?id=10202 + +• Don't make the ps backend link against zlib anymore, since it + doesn't require it (Carl Worth). + +• Use "find !" rather than "find -not" for better portability (Thomas + Klausner). + + https://bugs.freedesktop.org/show_bug.cgi?id=10226 + +• Don't use unsupported visibility attribute "hidden" on Solaris + (Gilles Dauphin, Thomas Klausner). + + https://bugs.freedesktop.org/show_bug.cgi?id=10227 + +Optimization +------------ +• It was Behdad that suggested we focus strictly on bug fixes now that + we shipped so many performance improvements in 1.4.0, but it was + also Behdad that got distracted by the chance to remove a lot of + mallocs from cairo. Paths, gstates, trapezoids, splines, polygons, + and gradient color stops will now use small, stack-allocated buffers + in the most common cases rather than calling malloc as + often. (Behdad Esfahbod). And look for more from Mathias Hasselmann + soon. + Release 1.4.0 (2007-03-06 Carl Worth ) ========================================================= The many people[*] who have been working hard on cairo are very
