mex is open source and moving fast. Here's what's new in the CLI, and how we think about memory for AI coding teams.
Latest releases
v0.7.2
Source-backed graph retrieval
August 2026mex 0.7.2 makes the code graph useful as a first-response retrieval system. `mex graph scope` now returns the most relevant source declarations and execution flows under a hard token budget.
