This is a development release leading up to Pango-1.12.0, which
will be released just in time for GNOME-2.14.

Most changes in this release are optimizations.


 * This is unstable development release. While it has had
   fairly extensive testing, there are likely bugs
   remaining to be found. This release should not be used
   in production.

 * Installing this version will overwrite your existing
   copy of Pango-1.10. If you have problems, you'll need
   to reinstall Pango-1.10.1

 * Bugs should be reported to

About Pango

Pango is a library for layout and rendering of text, with an emphasis
on internationalization. Pango can be used anywhere that text layout
is needed, though most of the work on Pango so far has been done in
the context of the GTK+ widget toolkit. Pango forms the core of text
and font handling for GTK+-2.x.

Pango is designed to be modular; the core Pango layout engine can
be used with different font backends. There are two basic backends,
with multiple options for rendering with each.

 - Client side fonts using the FreeType and fontconfig libraries.
   Rendering can be with with Cairo or Xft libraries, or directly
   to an in-memory buffer with no additional libraries.

 - Native fonts on Microsoft Windows. (Optionally using Uniscribe
   for complex-text handling). Rendering can be done via Cairo
   or directly using the native Win32 API.

The integration of Pango with Cairo (
provides a complete solution with high quality text handling
and graphics rendering.

Dynamically loaded modules then handle text layout for particular
combinations of script and font backend. Pango-1.9 ships with a wide
selection of modules, including modules for Hebrew, Arabic, Hangul,
Thai, and a number of Indic scripts. Virtually all of the world's major
scripts are supported.

As well as the low level layout rendering routines, Pango includes
PangoLayout, a high level driver for laying out entire blocks of text,
and routines to assist in editing internationalized text.

Pango 1.11.0 depends on version 2.9.0 or newer of the GLib library;

Overview of changes between 1.10.1 and 1.11.0
* Line-breaking algorithm updated to Unicode 4.1.
* Code borrowed from GNU FriBidi resynched to version 1.0.7.
* New improved Tibetan shaper module. [Pema Geyleg]
* Bug fix in Khmer shaper module. [Jens Herden]
* Respect fontconfig reassignment of font pixelsize. [Funda Wang]
* Make OpenType GPOS handling more robust/correct. [Greg Aumann]
* Various documentation fixes and improvements.
* Various gcc warning fixes.
* Misc bug fixes.


* Add a lazy fixed-size per-font cache to map characters to glyphs,
  in the cairo backend. [Federico Mena Quintero]
* Optimize character to script mapping by adding a linear table for
  characters < U+2000, and also caching the last mid point in
  bsearch. [Federico, Matthias Clasen]
* Enabled mini-fribidi's trashstack instead of direct mallocs.
* Short circuit the bidi algorithm for provably unidirectional text.

* Use call tables in the OpenType layout code.
* Use quarks for accessing GObject data. [Federico]
* Open Pango modules with lazy-bind flags. [John Rice]
* Use new negative offsets in g_utf8_pointer_to_offset to avoid
  scanning from the beginning of line on cursor movement.
* Avoid redundant PANGO_IS_FC_FONT checks.
