+Overview of changes between 1.16.4 and 1.17.0
+==============================================
+
+General:
+
+- Text justification. A simple justification algorithm is implemented
+ that tries to justify by expanding spaces in the line, and if none
+ found, by adjust letter spacing. [Based on patch by Mathias
+ Hasselmann]
+
+- The pango_script_get_sample_language() function is modified to use
+ the value of environment variables PANGO_LANGUAGE or LANGUAGE
+ (checked in that order) to make guess better languages for scripts.
+ The env var should be a list of language tags, like "en:fa" for
+ example where in effect makes Pango choose Persian (fa) fonts
+ instead of Arabic (ar) fonts when a run of text in the Arabic script
+ is found in an otherwise non-Arabic layout.
+
+ This trick is also useful for East Asian languages. For example a
+ Japanese user that cannot set her primary language to Japanese can
+ still set PANGO_LANGUAGE="ja" and Pango will map CJK characters to
+ Japanese.
+
+ The LANGUAGE env var is a standard gettext variable listing
+ languages the user wants to receive UI translated messages in.
+ However, since most packages don't provide separate English
+ translations, setting LANGUAGE="en:ja" doesn't have the intended
+ effect and UI messages will be shown in Japanese. For these
+ situations one can use LANGUAGE="en:C:ja". Pango skips the special
+ language tag 'C'.
+
+- Simplified embedded-shape rendering with pangocairo backends do.
+ [Richard Hult]
+
+- New header file: Moved PangoLanguage APIs into its own header
+ pango-language.h, which is included from pango-types.h.
+
+- ATSUI backend now lists synthesized italic faces like other
+
+- Misc optimizations and fixes.
+
+OpenType Layout Engine Improvements:
+
+- Vertical glyph variants are not selected in vertical text if the
+ font supports them.
+
+- Instead of hardcoded OpenType script tag in each module, and using
+ Default Language System unconditionally, Pango will now find and use
+ the script/lang-sys pair that best matches the detected script and
+ language of a run of text. Moreover, it also applies the OpenType
+ 'locl' feature.
+
+ These, plus the PANGO_LANGUAGE env var, give font designers and
+ users lots of options to provide/choose language-specific glyph
+ variants.
+
+ Only basic, arabic, and syriac modules updated to take advantage of
+ the new support so far.
+
+New pango-view command line options:
+
+ --align
+ --justify
+ --language
+
+Public API Changes:
+
+- New public pangocairo API:
+
+ PangoCairoShapeRendererFunc
+ pango_cairo_context_set_shape_renderer()
+ pango_cairo_context_get_shape_renderer()
+
+ These are used by the default pangocairo renderer to render shape
+ attributes (see examples/cairoshape.c). Cairo-based PangoRenderer
+ implementations outside Pango may want to implement the draw_shape()
+ method similarly to provide compatibility with these new APIs. (See
+ bug #437533 for GdkPangoRenderer for example.)
+
+- Other public API changes:
+
+ New is_expandable_space member in PangoLogAttr
+ New macro PANGO_UNITS_ROUND()
+
+- New OpenType engine API. These are engine API, for use by Pango
+ modules, and typically need not to be bound by language bindings:
+
+ PANGO_OT_NO_FEATURE
+ PANGO_OT_NO_SCRIPT
+ PANGO_OT_TAG_DEFAULT_SCRIPT
+ PANGO_OT_TAG_DEFAULT_LANGUAGE
+ PangoOTFeatureMap
+ PangoOTRulesetDescription
+ pango_ot_ruleset_get_for()
+ pango_ot_ruleset_new_for()
+ pango_ot_ruleset_maybe_add_feature()
+ pango_ot_ruleset_maybe_add_features()
+ pango_ot_ruleset_description_hash()
+ pango_ot_ruleset_description_equal()
+ pango_ot_ruleset_description_copy()
+ pango_ot_ruleset_description_free()
+ pango_ot_tag_from_script()
+ pango_ot_tag_to_script()
+ pango_ot_tag_from_language()
+ pango_ot_tag_to_language()
+
+- Bugs fixed in this release:
+
+ Bug 64538 – pango_layout_set_justify() doesn't work
+ Bug 325714 – Pango should respect $LANGUAGE
+ Bug 414264 – Pango vertical writing support is different with real
+ CJK usage.
+ Bug 416515 – Time is not aligned with date on vertical panel
+ Bug 429397 – Updated MS Mincho/Gothic are not listed in font dialog
+ properly on Vista/
+ Bug 433805 – [Atsui] Approximate char/digit width width often 0
+ (worked around)
+ Bug 434160 - [atsui] Italic versions of some faces can't be created
+ Bug 435709 – pango_cairo_context_[sg]et_shape_renderer()
+ Bug 355789 – Pango misaligns word-wrapped text due to trailing
+ whitespace
+ Bug 436154 – Error building the pango.modules file while cross
+ compiling
+ Bug 436988 – Adding PangoScript to PangoAnalysis
+ Bug 437534 – pango_language_includes_script is buggy
