+Overview of changes leading to 0.9.14 |
+Thursday, March 21, 2013 |

+Overview of changes leading to 0.9.13 |
+Thursday, February 25, 2013 |
+===================================== |
+ |
+- Build fixes. |
+- Ngapi HarfBuzz Hackfest in London (February 2013): |
+ * Fixed all known Indic bugs, |
+ * New Win8-style Myanmar shaper, |
+ * New South-East Asian shaper for Tai Tham, Cham, and New Tai Lue, |
+ * Smartly ignore Default_Ignorable characters (joiners, etc) wheb |
+ matching GSUB/GPOS lookups, |
+ * Fix 'Phags-Pa U+A872 shaping, |
+ * Fix partial disabling of default-on features, |
+ * Allow disabling of TrueType kerning. |
+- Fix possible crasher with broken fonts with overlapping tables. |
+- Removed generated files from git again. So, one needs ragel to |
+ bootstrap from the git tree. |
+ |
+API changes: |
+- hb_shape() and related APIs now abort if buffer direction is |
+ HB_DIRECTION_INVALID. Previously, hb_shape() was calling |
+ hb_buffer_guess_segment_properties() on the buffer before |
+ shaping. The heuristics in that function are fragile. If the |
+ user really wants the old behvaior, they can call that function |
+ right before calling hb_shape() to get the old behavior. |
+- hb_blob_create_sub_blob() always creates sub-blob with |
+ HB_MEMORY_MODE_READONLY. See comments for the reason. |
+ |
