Hi,
I maintain a working cluster which is in version 1.1.1 and I'm planning to
upgrade to version 1.3.0 which is released the previous week. I wanted to
ask whether it is compatible to upgrade or whether I will have any known
issues/problems, what to expect in general.
Thank you very much
Thomas

It was just mentioned on IRC there is a bug that may cause problems with
mixed version clusters, specifically with 1.3.0, that can cause shards to
go unallocated.
It's been recommended to wait until 1.3.1 which will contain a fix and is
not far off.
