error msg in rspamd GUI history after update to 3.1

Hi,
i get errors in the rspamd gui after updating to 3.1. Never saw this error before.

2.11.2021, 12:32:13 controller 55476 csession db5296 learn error: all learn conditions denied learning spam in default classifier

In the rspamd.log it is this chapter:

Code:

I suggest after skipping, because rspamd knows the spam it throws this message. But why it writes down an error and how can i get rid of this?

 

When was RSPAMD 3.1 released?

 

I got the update yesterday with apt-get
Rspamd daemon version 3.1

https://www.pro-linux.de/cgi-bin/DBApp/check.cgi?ShowApp..14885.100

 

Strange, rspam.com tells nothing about released 3.1, but apt get has it available.
