+FAQ
+---
+
+### Why must `zsh-syntax-highlighting.zsh` be sourced at the end of the `.zshrc` file?
+
+`zsh-syntax-highlighting.zsh` wraps ZLE widgets.  It must be sourced after all
+custom widgets have been created (i.e., after all `zle -N` calls and after
+running `compinit`).  Widgets created later will work, but will not update the
+syntax highlighting.
+
+### How are new releases announced?
+
+There is currently no "push" announcements channel.  However, the following alternatives exist:
+
+- GitHub's RSS feed of releases: https://github.com/zsh-users/zsh-syntax-highlighting/releases.atom
+- An anitya entry: https://release-monitoring.org/project/7552/

+# Changes in version 0.3.0
+
+
+## Added highlighting of:
+
+- suffix aliases (requires zsh 5.1.1 or newer):
+
+        alias -s png=display
+        foo.png
+
+- prefix redirections:
+
+        <foo.txt cat
+
+- redirection operators:
+
+        echo > foo.txt
+
+- arithmetic evaluations:
+
+        (( 42 ))
+
+- $'' strings, including \x/\octal/\u/\U escapes
+
+        : $'foo\u0040bar'
+
+- multiline strings:
+
+        % echo "line 1
+        line 2"
+
+- string literals that haven't been finished:
+
+        % echo "Hello, world
+
+- command words that involve tilde expansion:
+
+        % ~/bin/foo
+
+
+## Fixed highlighting of:
+
+- quoted command words:
+
+        % \ls
+
+- backslash escapes in "" strings:
+
+        % echo "\x41"
+
+- noglob after command separator:
+
+        % :; noglob echo *
+
+- glob after command separator, when the first command starts with 'noglob':
+
+        % noglob true; echo *
+
+- the region (vi visual mode / set-mark-command) (issue #165)
+
+- redirection and command separators that would be highlighted as `path_approx`
+
+        % echo foo;‸
+        % echo <‸
+
+    (where `‸` represents the cursor location)
+
+- escaped globbing (outside quotes)
+
+        % echo \*
+
+
+## Other changes:
+
+- implemented compatibility with zsh's paste highlighting (issue #175)
+
+- `$?` propagated correctly to wrapped widgets
+
+- don't leak $REPLY into global scope
+
+
+## Developer-visible changes:
+
+- added makefile with `install` and `test` targets
+
+- set `warn_create_global` internally
+
+- document release process

@@ -5,6 +5,13 @@ Utility scripts for testing zsh-syntax-highlighting highlighters.
 
 The tests expect the highlighter directory to contain a `test-data` directory with test data files. See the [main highlighter](../highlighters/main/test-data) for examples.
 
+Each test should define the array parameter `$expected_region_highlight`.
+The value of that parameter is a list of `"$i $j $style"` strings.
+Each string specifies the highlighting that `$BUFFER[$i,$j]` should have;
+that is, `$i` and `$j` specify a range, 1-indexed, inclusive of both endpoints.
+
+_Note_: `$region_highlight` uses the same `"$i $j $style"` syntax but interprets the indexes differently.
