+    Fix reverse_range() to only reverse alt array if positions are used
+
+    In hb-coretext, when we were using scratch buffer for book-keeping,
+    a reverse_range() caused by the notdef-insertion loop could mess up
+    our log_clusters.  Ouch!

+    [layout] Fix comparison of GlyphID and hb_codepoint_t
+
+    Before, the IntType::cmp functions providing this and was truncating
+    the hb_codepoint_t to 16bits before comparison.  I have no idea how
+    this was never discovered, and I'm too lazy to try to reproduce this
+    with Pango (which uses non-16bit codepoint numbers for missing
+    glyphs).

+
+    [lookup] Don't initialize skippy if coverage match fails
+
+    Currently:
+
+      - Initializing skippy is very expensive,
+
+      - Our lookup accelerator (using set-digests) can be very ineffecite,
+
+    As such, we end up many times initializing skippy but then failing
+    coverage check.  Reordering fixes that.
+
+    When, later, we fix our accelerator to have truly small false-positive
+    rate (for example by using the frozen-sets), then we might want to
+    reorder these checks such that we wouldn't calculate coverage number
+    if skippy is going to fail.
+
+    This shows a 5% speedup with Roboto already.

+    hb_frozen_set_t, hoping to get a huge speedup for busy lookups

+
+    Fix build with MSVC on CE
+
+    This code is C++ only. There isn't a single C++ compiler that fails to
+    understand the "inline" keyword, since it's required by C++98. Any
+    compiler older than C++98 is likely to choke on the template usage
+    further down, so this isn't necessary.
+
+    Moreover, the C++ standard says you cannot define macros.
+    [lib.macro.names] says "Nor shall such a translation unit define
+    macros
+    for names lexically identical to keywords." -- technically, it's a
+    promise that the Standard Library headers won't do it, the wording
+    means
+    that the entire translation unit won't do it, which implies no source
+    can do it.
+
+    MSVC complains about it:
+    fatal error C1189: #error : The C++ Standard Library forbids
+    macroizing
+    keywords. Enable warning C4005 to find the forbidden macro.

+    [API] Add hb_buffer_add_latin1()
+
+    This is by no ways to promote non-Unicode encodings.  This is an entry
+    point that takes Unicode codepoints that happen to all be the first
+    256 characters and hence fit in 8bit strings.  This is useful eg
+    in Chrome
+    where strings that can fit in 8bit are implemented that way, and this
+    avoids copying into UTF-8 or UTF-16.
+
+    Perhaps we should rename this to hb_buffer_add_codepoints8().
+    I'm also
+    curious if anyone would be really interested in
+    hb_buffer_add_codepoints16().
+
+    Please discuss!

+
+    The visual encoding is already the current practice of encoding New
+    Tai Lue on the web anyway:
+    http://www.unicode.org/L2/L2014/14195-newtailue.txt

+
+    Over time we have had added NO_HINTING all over the place in hb-ft.
+    Finish it off.
+    Not setting ppem on hb-font disables get_contour_point() calls which
+    is good anyway.

+
+    [ft] Add hb_ft_face_create_referenced() and
+    hb_ft_font_create_referenced()
+
+    When I originally wrote hb-ft, FreeType objects did not support
+    reference
+    counting.  As such, hb_ft_face_create() and hb_ft_font_create() had a
+    "destroy" callback and client was responsible for making sure
+    FT_Face is
+    kept around as long as the hb-font/face are alive.
+
+    However, since this was not clearly documented, some clienets didn't
+    correctly did that.  In particular, some clients assumed that
+    it's safe
+    to destroy FT_Face and then hb_face_t.  This, indeed, used to work,
+    until
+    45fd9424c723f115ca98995b8f8a25185a6fc71d, which make face destroy
+    access
+    font tables.
+
+    Now, I fixed that issue in 395b35903e052aecc97d0807e4f813c64c0d2b0b
+    since
+    the access was not needed, but the problem remains that not all
+    clients
+    handle this correctly.  See:
+
+      https://bugs.freedesktop.org/show_bug.cgi?id=86300
+
+    Fortunately, FT_Reference_Face() was added to FreeType in 2010,
+    and so we
+    can use it now.  Originally I wanted to change hb_ft_face_create() and
+    hb_ft_font_create() to reference the face if destroy==NULL was
+    passed in.
+    That would improve pretty much all clients, with little undesired
+    effects.
+    Except that FreeType itself, when compiled with HarfBuzz support,
+    calls
+    hb_ft_font_create() with destroy==NULL and saves the resulting
+    hb-font on
+    the ft-face (why does it not free it immediately?).  Making hb-face
+    reference ft-face causes a cycling reference there.  At least,
+    that's my
+    current understanding.
+
+    At any rate, a cleaner approach, even if it means all clients will
+    need a
+    change, is to introduce brand new API.  Which this commit does.
+
+    Some comments added to hb-ft.h, hoping to make future clients
+    make better
+    choices.
+
+    Fixes https://bugs.freedesktop.org/show_bug.cgi?id=75299

+    Avoid accessing layout tables at face destruction
+
+    "Fixes" https://bugs.freedesktop.org/show_bug.cgi?id=86300
+
+    Based on discussion someone else who had a similar issue, most
+    probably
+    the user is releasing FT_Face before destructing hb_face_t /
+    hb_font_t.
+    While that's a client bug, and while we can (and should) use FreeType
+    refcounting to help avoid that, it happens that we were accessing
+    the table when we didn't really have to.  Avoid that.

+    Fail blob creation if length overflows or is too large
+
+    Fail if blob start plus length overflows; or if blob length
+    is greater than 2GB.  It takes a while for fonts to get to that
+    size.  In the mean time, it protects against bugs like this:
+
+      http://www.icu-project.org/trac/ticket/11450
+
+    Also avoids some weird issues with 32bit vs 64bit systems
+    as we accept length as unsigned int.  As such, a length of
+    -1 will cause overflow on 32bit machines, but happily
+    accepted on a 64bit machine.  Avoid that.

+    In hb_ot_collect_glyphs(), don't recurse to a lookup more than once
+

+To enable HarfBuzz bindings for Python among other languages, make sure
+you have latest version of gobject-introspection compiled, and then
+run autogen.sh (if building from git), and then:
+
+  ./configure --with-gobject --enable-introspection
+
+Make sure that gobject-introspection is enabled then in the final report.
+
+Compile and install.
+
+Make sure you have the installation lib dir in LD_LIBRARY_PATH, as needed
+for the linker to find the library.
+
+Then make sure you also have GI_TYPELIB_PATH pointing to the resulting
+$prefix/lib/girepository-* directory.
+
+Make sure you have pygobject installed.  Then check that the following
+import works in your Python interpretter:
+
+  from gi.repository import HarfBuzz
+
+If it does, you are ready to call HarfBuzz from Python!  Congratulations.
+See src/sample.py.
+
+The Python API will change.  Let us know on the mailing list if you are
+using it, and send lots of feedback.
