    libctf: add a NEWS
    
    I'm dividing this into three groups for now: new features, bugfixes,
    and bugfixes also present on a stable branch.
    
    Only user-visible bugfixes, not build-system fixes, are listed.

+Changes in 2.37:
+
+* New features
+
+** Add ctf_lookup_by_symbol name and ctf_arc_lookup_symbol_name, analogues of
+   existing ctf_lookup_by_symbol and ctf_arc_lookup_symbol, but looking up
+   symbols by name rather than symbol number.  This also works in places where no
+   symbol number is known, like in object files and dynamic dicts created by
+   ctf_create.
+
+* Bugfixes
+
+** Avoid duplicating or losing types of data object symbols when
+   ld -r is used
+
+** Prohibit typedefs with no name; prevent the linker/deduplicator
+   producing such typedefs
+
+* Bugfixes, also on 2.36 branch
+
+** Prevent ctf_lookup_by_name returning success when
+   looking up nonexistent pointer types
+
+** Fix ctf_type_add copying of structs with unnamed members
