Upcoming C-tor security release - 0.4.9.12
by David Goulet 03 Sep '26

03 Sep '26

Greetings everyone! Next Tuesday, September 8th, we will do a C-tor release (0.4.9.12) containing fixes for a set of high severity issues. And then, as a heads up, C-tor will likely enter a release cadence every 2-3 weeks for the foreseeable coming month(s) as we continue to fix more and more security issues we received from this new reality that we happen to all be in where LLMs are in an echo chamber stuck in a tight loop over our C code ;). Cheers! David -- NeD2Y6SX2RdikJfl0oSgWfrO+dQkz9M114CVJBuzW3w=
