I just released Tinymail’s pre-release 0.0.7. This release is mostly a bugfix release. 
We’ve been fixing memory problems and a few crashers in features that we introduced in pre 0.0.6. And because I have been telling people this about every pre release, this one too is probably one of the last pre releases before a final release!
The release notes can be found here. Downloads here. API documentation here. And the friendly guys doing Modest have made a beta release based on Tinymail’s trunk of today (which is the same version of the code as this pre-release 0.0.7). Install Modest on your N800 and N810 by tapping here.
