+Release 1.15.4 (2016-12-9 Bryce Harrington <firstname.lastname@example.org>)
+This new snapshot incorporates changes over the past year since the
+1.15.2 snapshot, including all the fixes from the 1.14 release series.
+Of particular note in this snapshot is a wealth of work by Adrian
+Johnson to enhance PDF support, as well as numerous bug fixes provided
+by him and other contributors.
+For a complete log of changes since the last release, please see:
+* The PDF backend has gained support for a range of widely used
+ features, including thumbnails, page labels, metadata, document
+ outlines, structured text, hyperlinks, and tags. Tags permit adding
+ logical info such as headings, tables, figures, etc. that facilitates
+ indexing, accessibility, text reflow, searching, and extraction of the
+ tagged items to other software. For details on this new PDF
+ functionality, see:
+ Added a cairo API to set up Win32 surfaces for HDC with alpha channels.
+ New API for added PDF functionality (see above), and new error
+ status item for problems relating to PDF tagging.
+ New error status items for handling of GDI, libfreetype, and libpng
+ errors, respectively.
+* Bug fixes from 1.15.2 (see the 1.15.2 NEWS for details)
+* Fix playback of recording surfaces into PDF surfaces, where objects
+ with negative coordinates were not getting drawn. To address this,
+ the coordinate systems for PDF and PS have been changed to match
+ cairo's coordinate system. This allows recording surfaces to be
+ emitted in cairo coordinates, and results in the same origin being
+ used for all operations when using the recording surface XObject.
+ Test cases for PDF and PS have also been updated accordingly.
+ (Bug #89232)
+* Fix "invalidfont" error on some printers when printing PDFs with
+ embedded fonts that have glyphs (such as spaces) with
+ num_contours == 0. (Bug #79897)
+* Fix missing glyphs such as thin dashes, which get scaled to 0 in
+ userspace and thus have their drawing operations culled. (Bug #94615)
+* Fix other oddities caused by variously idiosyncratic fonts.
+* Fix deadlock when destruction of a scaled font indirectly triggers
+ destruction of a second scaled font, causing the global cache to be
+ locked twice. (Bug #93891)
+* Fix X errors reported to applications when shmdt() is called before
+ the Attach request is processed, due to missing xcb and xlib calls.
+* Fix random failure in record-paint-alpha-clip-mast test case, caused
+ by an incorrect assumption that a deferred clear can be skipped.
+ (Bug #84330)
+* Fix crash when dealing with an XShmGetImage() failure, caused by a
+ double free in _get_image_surface(). (Bug #91967)
+* Fix invalid execution of ASCII85 data by the PS interpreter that the
+ image operator didn't use, by flushing the extraneous data after
+ drawing the image. (Bug #84811)
+* Fix decoding of Adobe Photoshop's inverted CMYK JPEG files in PDF
+* Fix unbounded surface assertion in win32-print code.
+* Fix a data race in freed_pool discovered by Firefox's cairo usage.
+ The patch adads atomic int load and store functions, with relaxed
+ memory ordering. (Bug #90318)
+* Cleanup debugging text sent to stdout instead of log. (Bug #95227)
+* Fix build issue when using non-GNU strings utility. (Bug #88639)
+* Fix build of cairo modules as regular modules, not as versioned shared
+ libaries. (Bug #29319)
+* Fix build on win32 using gcc 5.4.
+* Fix build of script backend to require zlib.
+* Update test suite reference images using Debian Jessie 64-bit and
+ poppler current as of June, 2016.
+* Various improvements to documentation and tests, compiler warning
+ fixes, and an assortment of code refactoring and cleanup.
