Is there a 1.5.1 update to 1.5 available for download, if so

and is there a compiled list of the known bugs for live on pc's and mac's organized by operating systems? if so would somebody post it, I think it would be good for us to know so we don't keep bothering the programmers with issues they already know about and are currently working on, this way when we encounter some trouble we can check the bug sheet first.
