+ * NEWS: Accidentally forgot to back out the sorted wildcard
+ enhancement in 3.82, so update NEWS.
+ Also add NEWS about the error check for explicit and pattern
+ targets in the same rule, added to 3.82.
+
+ * main.c (main): Add "oneshell" to $(.FEATURES) (forgot to add
+ this in 3.82!)
+
+ * read.c (parse_file_seq): Fix various errors parsing archives
+ with multiple objects in the parenthesis, as well as wildcards.
+ Fixes Savannah bug #30612.

+
+ * main.c (main): Expand MAKEFLAGS before adding it to the
+ environment when re-exec'ing. Fixes Savannah bug #30723.

As a result of parser enhancements, three backward-compatibility issues
