+======================================================================
+
+ Major changes between "less" versions 458 and 466
+
+* Don't overwrite history file; just append to it.
+
+* New command ESC-G goes to end of currently buffered data in a pipe.
+
+* In more-compatible mode, make the -p option apply to every file opened,
+ not just the first one.
+
+* In more-compatible mode, change the -e option to work like -E, not -EF.
+
+* Treat multiple CRs before LF are like one CR (all the CRs are hidden).
+
+* Ignore -u/-U setting while viewing help file, so that
+ underline and bold chars are displayed correctly.
+
+* Improve detection of "binary" files in UTF-8 mode.
+
+* Fix bug with ++ commands.
+
+* Fix bugs and improve performance in ampersand filtering.
+
+* Automate construction of Unicode tables from Unicode database.

+ * need to maintain a usage bitmap or freelist and can just return nodes
+ * from the pool in-order until capacity is reached.
