It never takes the community long to produce needed documentation for new features in Blender. So it is no surprise that even though Blender 2.5 is still in beta, there are already a rather nice number of tutorials available to help you get the most out of the newest incarnation of Blender.
BlenderCookie.com has been using Blender 2.5 se-ries for their video tutorials for some time now and has even started covering new features only found the latest test builds. In addition to full length video tutorials using 2.5, they have alos been releasing shorter videos that cover specific tools and options in their Tips series. The BlenderCookie 2010 CG Cookie Blender Training Series is now live with Part 1 and the modeling section of part 2 available for purchase and download.
BlenderGuruhas been releasing tutorials done in 2.5, both in video and text format as well as new pdf ebook, The WOW Factor . He has started a new series of tutorials with each month focusing on a specific theme. I encourage you to chek out the
Weatherseries, his snowis amazing and his lightning tutorialis electrifying.
Kernon Dillon (BlenderNewbies)has not only been producing video tutorials for 2.5, he is alos busily working on a DVDfull of brand new content for 2.5.
And of course he has started a new series of modeling exercises that focus on technique and not just the end product, which are very educational and informative.
