 ** Requirements
 Biber version 2.8 is required for biblatex 3.8
 
+** Bugfix for CLDR sorting issues
+   Some CLDR sort tailoring was broken in version 2.7. This was due to an invisible
+   Unicode::Collate library change which was not noticed until after 2.7 was released and is fixed in version 2.8.
+** Name handling enhancements
+   Name handling is now fully generalised to cover arbitrary name parts.
+   The final few pieces have been completed to allow fully customisable
+   name handling, allowing for better internationalisation. The code for
+   name uniqueness calculation and label generation for names is now fully
+   abstracted: templates created with ~\DeclareUniquenameTemplate~ and
+   ~\DeclareLabelalphaNameTemplate~ may now be specified at per-refcontext,
+   per-entry, per-namelist and per-name scope, which allows complete
+   control over all aspects of name usage. See the comments in the enhanced
+   ~93-nameparts.tex~ example file.

 ** In order to standardise terminology, some commands and options have dropped the "scheme" naming convention and switched to "template"

+  The new \DeclareExtradate command allows users to track authoryear
+  disambiguation in arbitrary ways now, for example allowing disambiguation
