+	* 30272 (tweaked): Src/exec.c: most failures of fork() cause
+	non-interactive shells to exit nonzero; bad options to "exec"
+	cause exit under POSIX_BUILTINS behavior.
+
+	* unposted (see users/16715): Doc/Zsh/options.yo: document the
+	effects of HASH_LIST_ALL on spelling correction.
+
+	* 30184: Src/hashtable.c: the HASH_EXECUTABLES_ONLY test matches
+	the test used during path search in exec.c:iscom().
+
+	* unposted (see 30090): Functions/Misc/add-zsh-hook: add -h and
+	-L options for help text and a list of extant hooks respectively.
+
+	* unposted (see users/16697): Functions/Misc/zkbd: select a more
+	reasonable output file name when the DISPLAY variable refers to a
+	local socket file (MacOS); fix problem with writing the output
+	file when the user overrides the default value of TERM.
