If you're using BlogEngine (like me), then you'll be pleased to know that version 1.4 has been released.
Al Nyveldt has come up with an upgrade guide to ease the transition.
Last, if you need a few reasons to upgrade, here's a taste of what's new:
- Universal database provider (MySQL, SQL Server, VistaDB, Oracle etc.)
- Drag ‘n drop widget framework (prototype video)
- Author profiles using ASP.NET profile provider
- Password encryption
- Better performance
- Tag selector in control panel
- Semantic formats (FOAF, SIOC and APML)
I'm planning my migration strategy, the first step of which entails finding time to do it. Remember to backup EVERYTHING before you get started. Better safe than sorry.
