FileBot

A bunch of new release groups were added to the release groups GitHub file, but FileBot on my computer still doesn't recognise them after waiting a few days.
Is there any way for me to update the locally stored groups myself? OS is Windows.

Thanks in advance

It might take up to 2 weeks for them to auto-update trickle down to your machine. You can't maintain your own data files, but you can clear the local cache to speed it up by maybe a week. Updated data files are only published once a week though.
