According to Nokia Beta Labs, though curiously not according to my Windows Vista laptop, there's a shiny new beta of Ovi Suite 2.1 available - according to my logs, the change is from v2.1.0.78 to 2.1.0.82. Do bear in mind this is still definitely classed as a beta, so please feedback any problems via the Beta Labs page. There's a changelog below, should you need convincing to update.

• Fixed for Thunderbird 3.0 support, now you can choose Thunderbird 3.0 for contacts sync in Nokia Ovi Suite
• Fixes for multiple crash errors detected during Beta testing, for example related to maps view and calendar sync
• Improvements in overall Nokia Ovi Suite stability
• Many fixes to sync reliability
• Fixes issues related to ovi.com contacts sync (automatic sync option for contacts didn’t work properly)
• Improved checking for new software updates and other fixes to software updater features
• Fixes to video support, improvements into video support stability
• Fix for SIS application installation (double clicking SIS now works properly and starts installation procedure into device)
• Many fixes to Nokia Ovi Suite UI localizations (languages)
