I just released a new version of Gabble, my native OS X Yammer client, with support for attachments, tags, and some other small enhancements (view the full release notes here). If you’re running Gabble 1.0, you can update directly from within the application itself. If not, you can grab a copy on the Gabble page.

If you encounter any bugs or have any feedback/feature requests, feel free to send me an email or post in the comments. Enjoy!
