Adobe Premiere Pro CS4 Version 4.1 Update (http://videography.com/article/81758)

I don't see the updates on Adobe's Web site, nor are the available through the Adobe Updates manager. The Latest Updates list at Adobe - Downloads (http://www.adobe.com/downloads/) doesn't list anything new, either. Is this a forthcoming update, or am I looking in the wrong spot?
Thanks,

It's not being released until late may.

Finally 64bit - yes!!!

Its not 64bit as such. It is just able to make better use of the additional RAM available to 64bit O/S.

I don't see any information here about 4.1 having improved memory management? I saw earlier reports suggesting that this would be addressed.

Poor memory management is my main gripe with Premiere.

If you read the whitepaper http://www.adobe.com/products/creativesuite/production/pdfs/cs4_production_premium_64bit_wp.pdf it explains how with a 64bit O/S, each app can address 2gb each instead of sharing 3gb amongst them all.

Thanks - 64 bit is clearly the future. But I'd also like to know whether Premiere 4.1 will be better in general at giving back memory it doesn't need.

I currently have a 32 bit machine with 4 GB RAM (in practice ~3.6 GB available to the OS). Should be enough for simple editing but Premiere's memory use climbs and climbs until it falls over. This is a well documented issue.

A recent post on the Adobe forum said 4.1 was going to address this issue. But I don't see confirmation of this point in this paper.

I have the exact opposite problem: I would LOVE Premiere to take over all of my RAM, but it doesn't. It thrashes the swapfile, reloads clip thumbnails every time i scroll a page up or down in Bins, but it keeps under one gig at all times. No memory "tuning", no matter if I use Vista, XP, 32b or 64b, or even Leopard. Strange, right?
