+zsh (5.7.1-test-3-1) experimental; urgency=low
+
+ From the upstream README of 5.7.1-test-3:
+
+ > The history expansion !:1:t2 used to be interpreted such that the 2
+ > was a separate character added after the history expansion. Now it is
+ > an argument to the :t modifier.
+ >
+ > For example
+ >
+ > % echo /my/interesting/path
+ > % echo !:1:t2
+ >
+ > used to echo "path2", but now echoes "interesting/path".
+ >
+ > The behaviour of :h has similarly changed.
+ >
+ > The behaviour has also changed in forms such as ${foo:t2) and *(:t2),
+ > but in those cases the previous behaviour was not meaningful.
+ >
+ > The vcs_info function VCS_INFO_quilt-dirfind now returns a string value
+ > by setting $REPLY. Previously it printed the value to standard output.
+ > This only affects you if you override that function in your dotfiles.
+ >
+ > The cd and chdir builtins no longer interpret operands like -1 and +2 as
+ > stack entries when POSIX_CD is enabled.

+zsh (5.4.2-1) unstable; urgency=medium
+
+ From the upstream README of 5.4.1:
+
+ > The default behaviour of code like the following has changed:
+ >
+ > alias foo='noglob foo'
+ > foo() { print function body; }
+ >
+ > When this is encountered in a start-up file, or other place where
+ > input was read line by line, "foo" is in command position and is
+ > expanded as an alias before the function definition takes place. In
+ > previous versions of the shell, this caused two functions "noglob" and
+ > "foo" to be defined. Any expansion of an alias in a function
+ > definition is nearly always an unintended effect, as well as hard to
+ > detect, so has been made an error. (The option setting
+ > NO_MULTI_FUNC_DEF turned this case into an error, but did not help
+ > with other cases and is off by default.) The alternative, of not
+ > expanding the alias, was rejected as it was more difficult to achieve
+ > in the parser and also would silently change the shell's behaviur
+ > between versions. A new option, ALIAS_FUNC_DEF, has been added, which
+ > can be set to make the shell behave as in previous versions. It is in
+ > any case recommended to use the "function" keyword, as aliases are not
+ > expanded afterwards.
+
+ The common error message triggered by this change looks as follows:
+
+ > zsh: defining function based on alias `foo'
+ > zsh: parse error near `()'
+
+ See https://bugs.debian.org/871816 for more information.

+zsh (5.0.0-1) unstable; urgency=low
+
+ This update includes a rewrite of keyboard handling in `/etc/zsh/zshrc'.
+
+ The used method should be quite a bit more robust than the old one, and
+ should work out of the box for every terminal with a working terminfo entry.
+
+ If you do not want Debian's zshrc to mess with your keyboard setup, set the
+ following variable in your `.zshenv' file:
+
+ DEBIAN_PREVENT_KEYBOARD_CHANGES=yes
+
+ This change also removes the controversial vi-* bindings for the up and down
+ cursor keys (which was reported as #383737 and led to confusion with a
+ substantial number of users). If you want them back use the following snippet
+ in your `.zshrc' file (and without the above variable set):
+
+ for i in viins vicmd; do
+ bindkey -M "$i" "${key[Up]}" vi-up-line-or-history
+ bindkey -M "$i" "${key[Down]}" vi-down-line-or-history
+ done
+ unset i
