Re: Wire Posts in bp 1.2
The usage of @ may have been a twitter hack, but it came from using it as a way to acknowledge or direct a comment at a user when a threaded option wasn’t available. We use it even here in these very forums quite often, because we can’t directly reply to one another.
Deprecated code, the wire, and the status update components are totally removed from the BuddyPress 1.2 core and will be available in a separate BuddyPress Backwards Compatibility plugin. If you desire to use those components, or are using a custom theme that uses old function names or loops, you will be required to install and activate this additional plugin to continue to use your old code.
This was done for three reasons:
1. Reduce the amount of legacy code in the core that is just hanging around not being used
2. Not give new comers 2 (or more) ways to do the same one thing
3. Influence plugin and theme developers to upgrade their code to be compatible with BuddyPress 1.2 sooner rather than later
More detailed instructions and details will come as the 1.2 launch comes closer, but this is the best way to make sure everyone is happy.
