When you go to Source Forge to explore the CSV of moodle/moodle/ there is a list of various tags. If you choose HEAD which should be 1.6 BETA as I saw elsewhere, you obtain a somewhat older version than the one you obtain when downloading the dayly produced HEAD .zip on the download page of moodle.org.
I have comments of people talking about 1.6.3 or 1.6.4 , these tags are not readily apparent in Source Forge ;
you see
- MOODLE_16_UTF8
- MOODLE_16_MULTIENROL
- MOODLE_16_AUTHREFACTOR
How to find the real up-to-date moodle 1.6 CSV?
