Good news all! Asterisk 20.0.0 is now available at https://downloads.asterisk.org/pub/telephony/asterisk/! Before upgrading remember to read the UPGRADE.txt document to see if there’s anything you need to do. It should be a fairly easy upgrade. You can also check the CHANGES document to see what has changed.
I’d also like to take this opportunity to remind everyone that Asterisk 16 has gone security fix only, with Asterisk 19 going security fix only shortly. You can keep up to date with this information on the wiki.
