The Tor Browser Release Schedule is influenced by Mozilla's Firefox Release schedule.
Currently, like Mozilla, we release Tor Browser updates (point releases) roughly every 6 weeks, with occasional bugfix releases in between. Beginning next year, point releases will be every four weeks.
Mozilla announce their upcoming Firefox releases on their Rapid Release calendar. Based on this, the next planned Tor Browser Releases are:
