TL;DR: Release 4.6.0 and 4.6.0-1 zcashd nodes will reach End of Service on or about April 13th, 2022. Prior to that time, all nodes must upgrade to 4.6.0-2 to avoid service interruptions.
Notable changes
4.6.0-2 is primarily a bugfix release that also bumps the End-of-Support height to May 16th. It backports bugfixes from v4.7.0-rc1, including a getblocktemplate deadlock fix, and several portability fixes.
Debian 9 “Stretch” is no longer supported from v4.6.0-2, due to its end-of-life on June 30th, 2022. This will allow us to direct more resources to supporting Debian 11 Bullseye, other Linux distributions, and other platforms such as Windows and macOS.
