There is no scheduled date for it yet. 2.4 release has just been voted for
Based on the version history (https://ignite.apache.org/download.cgi) one
could say that the average time between releases is about 2-3 months, so
it's quite possible that 2.5 will be released in that time frame, but there
are no guarantees for that. To note, there are also more frequent commercial
releases provided by third-party vendors.
