1.5.0b1
Pre-release
New feature since 1.4.104a1: Search filter allows easier selection of login for current website.
This is a candidate beta build to enable support for e10s (Firefox multi-process).
It's likely that the first beta to be released on AMO will come with a couple of further bug fixes and some updated translations but otherwise should be similar to this release.
There are a few known bugs but hopefully nothing that can't be worked around.
Keep lots of backup versions of your database and be prepared for fundamental features to behave a little differently than in the previous version (hopefully mostly in a good way but that won't hold in 100% of cases).
Note that downgrading to an earlier version of KeePassRPC might cause duplicate UUIDs to be added to your KeePass database. They relate only to the KeeFox tutorial samples so the KeePass repair feature in v2.29 will fix it up easily but it's something to be aware of in case you wonder what causes the warning to appear if you go back to KeeFox 1.4.
