GPEC v2.1.0

Open

Due by December 18, 2026

•Last updated Nov 13, 2026

It has become clear that a number of good new features are in the pipeline but not going to make it into v2.0. This milestone is intended to start collecting high priority feature PRs and issues that would fit together well into a quick follow-on minor release v2.1
