 ## Status
 
-It is currently a work in progress!
+This is still a work in progress, but the current version can
+already execute complex scripts,
+such as solving the Towers of Hanoi puzzle and performing
+arbitrary precision integer arithmetic.
+The commands `=`, `l`, `r`, and `w`, as well as in-place replacement
+are still missing.
 
 ## Installation
 
@@ -37,13 +42,21 @@ cargo run --release
 * In addition to `\n`, other escape sequences (octal, hex, C) are supported
   in the strings of the `y` command.
   Under POSIX these yield undefined behavior.
+* The substitution command replacement group `\0` is a synonym for &.
+* A `Q` command (optionally followed by an exit code) quits immediately.
+* The `q` command can be optionally followed by an exit code.
+* The `l` command can be optionally followed by the output width.
+* The `--follow-symlinks` flag for in-place editing.
 
 ### Supported BSD and GNU extensions
 * The second address in a range can be specified as a relative address with +N.
+* In-place editing of file with the `-i` flag.
 
 ### New extensions
 * Unicode characters can be specified in regular expression pattern, replacement
   and transliteration sequences using `\uXXXX` or `\UXXXXXXXX` sequences.
+* The `l` command lists Unicode characters using the `\uXXXX` and `\UXXXXXXXX`
+  sequences.
 
 ### Incompatibilities
 * The input is assumed to be valid UTF-8 (this includes 7-bit ASCII).
