I believe Nathan meens to not upload the new version of plugin to the cental 
repository unless everything is ready. We're in a difficult moment now (I guess 
this weekend only), when uploading new plugins to the central repossitory will 
mask the older versions for 1.8 users.

Don't be scarry, it's quite simple. Finding and replacing all QString methods 
to unicode methods was much worse for me :D

Actually no breaking change happened now, there would be just MUCH more 
switches (assuming that e.g. each formerly QString-type variable may be either 
QString or unicode). So in the simplest plugins you can still use them and 
make the plugin dual-API-compatible. Just remember to explicitly set both 
qgisMinimumVersion and qgisMaximumVersion, otherwise QGIS assumes 
qgisMaximumVersion at 1.999.

For more complex plugins it would be crazy to introduce billions of switches, 
so in practice it's much better to create separate versions.
