tl;dr :
- Hexchat IRC client app development stopped
- Linux Mint team was building IRC client to replace Hexchat
- The team tried Matrix and liked it
- Linux Mint’s communication channels are moving from IRC to Matrix
- The desktop app will be named Matrix to avoid confusion
DALnet appears to be alive and kicking. Since you’re maybe out of the loop, big drama happened with Freenode. Right now Libera Chat and OFTC appear to be the big names for IRC for open source software users.
Ah, far out. Thank you for the info. Maybe I’ll load up an IRC client and check them out!
