Release 1.0.3

This point release mainly fixes the following: - A bug in history expansion (set -H) where any use of the history comment character caused processing to be aborted as if it were an invalid history expansion. Affected e.g. 'echo ${#v}'. - A bug in command line options processing that caused short-form option equivalents on some built-in commands to be ignored after one use, e.g., the new read -a equivalent of read -A. - Ksh freezing or using excessive memory if HISTSIZE is assigned a pathologically large value. - A bug that caused ksh in the vi editor mode to crash or produce invalid completions if ESC = was used at the beginning of a line.

+### MAIN CHANGES between ksh 93u+m 1.0.2 and 1.0.3 ###
+
+This point release fixes the following:
+- An old bug in history expansion (set -H) where any use of the history
+  comment character caused processing to be aborted as if it were an invalid
+  history expansion.
+- A bug in command line options processing that caused short-form
+  option equivalents on some built-in commands to be ignored after one use,
+  e.g., the new read -a equivalent of read -A.
+- Ksh freezing or using excessive memory if HISTSIZE is assigned a
+  pathologically large value.
+- A bug that caused ksh in the vi editor mode to crash or produce invalid
+  completions if ESC = was used at the beginning of a line.
+
+### MAIN CHANGES between ksh 93u+m 1.0.1 and 1.0.2 ###
+
+This bugfix release fixes the interactive shell crashing when one of the
+predefined aliases (currently 'history' and 'r') is redefined, whether from
+a profile/kshrc script or manually. This crash occurred in two scenarios:
+1. when redefining and then unsetting a predefined alias;
+2. when redefining a predefined alias and then executing a shell script that
+   does not begin with a #! path.
+
+### MAIN CHANGES between ksh 93u+m 1.0.0 and 1.0.1 ###
+
+This is an urgent bugfix release that removes an incorrect exec
+optimization that was capable of terminating the execution of scripts
+prematurely in certain corner cases. It is known to make the build scripts
+of GNU binutils produce corrupted results if ksh is used as /bin/sh.
+See https://github.com/ksh93/ksh/issues/507 for more information.
