+MAIN CHANGES SINCE KSH 93U+M 1.0.0-BETA.1
+
+- Various fixes to the test/[ built-in command. It now supports all the same
+  operators as [[ (including =~, \<, \>) except for the different 'and'/'or'
+  operators. Note: test/[ remains deprecated due to its unfixable pitfalls.
+
+- Fixed a bug that could corrupt output if standard output is closed upon
+  initializing the shell.
+
+- Fixed a bug in the [[ compound command: the '!' logical negation operator
+  now correctly negates another '!', e.g., [[ ! ! 1 -eq 1 ]] now returns
+  0/true. Note that this has always been the case for 'test'/'['.
+
+- Fixed SHLVL so that replacing ksh by itself (exec ksh) will not increase it.
+
+- Miscellaneous bugfixes.
