Re: ATP and presentation service for Mizar updated to MML 5.23.1213

Dear Mizar Users,

the ATP and presentation service for Mizar (MizAR) is now running on a
bigger server in Prague with more generous parallelization (about 60
different strategies run simultaneously) and time limits.

Please change/customize the value of the Emacs variable
ar4mizar-server to "http://grid01.ciirc.cvut.cz/". The Mizar server in
Canada seems to be down at the moment.

The only MML version installed so far is 5.29.1227 .

Best,
Josef
