The 'early release notes' and the quick update email are what I have to
refer to for on-rev:

http://samples.on-rev.com/irev-engine-notes.txt    (mark's original notes)

here's additional info from a later mark w. email
-------------------------snip---------------------------
on-rev clients

* Mac OS X: http://www.on-rev.com/templates/onrev/files/onrevosx.dmg
* Windows: http://www.on-rev.com/templates/onrev/files/onrevwindows.exe

New Features:

new errormode property which specifies how error messages are handled
• inline: display errors html formatted within page output
• stderr: errors are not displayed but will appear in server error logs
• quiet: no error display

New $_POST_RAW variable

Fixes:

• include of empty file name no longer outputs spurious characters, now
throws an appropriate error (bad filename)
• engine crash when setting http headers
• PATH_TRANSLATED now contains the path to the running script file when the
requested url contains extra path info after the script path
• PATH_INFO contains the extra path info
