 # Version 8.0.0
 
+## Change
+
+As part of the Unicode upgrades TextLayout codepaths have been unified across
+all platforms. As a consequence the behaviour of TextLayout on Apple platforms
+will now be different in two regards:
+- With certain fonts, line spacing will now be different.
+- The AttributedString option WordWrap::byChar will no longer have an effect,
+  just like it didn't have an effect on non-Apple platforms previously. Wrapping
+  will now always happen on word boundaries.
+
+Furthermore, the JUCE_USE_DIRECTWRITE compiler flag will no longer have any
+effect.
+
+**Possible Issues**
+
+User interfaces using TextLayout and the WordWrap::byChar option will have their
+appearance altered on Apple platforms. The line spacing will be different for
+certain fonts.
+
+**Workaround**
+
+There is no workaround.
+
+**Rationale**
+
+The new, unified codepath has better support for Unicode text in general. The
+font fallback mechanism, which previously was only available using the removed
+codepaths is now an integral part of the new approach. By removing the
+alternative codepaths, text layout and line spacing has become more consistent
+across the platforms.
