What was just updated and why?

It would be really cool if you'd update the README to say things like:

UPDATE (2026-Apr-04): blah blah blah because blah blah

So that the rest of us who downloaded your quant prior to April 4 know you updated it, and why.

Thanks.

yeah i just grabbed this a few hours ago so im very interested to know what's updated, especially with how fast llamacpp fixes are coming out etc, hoping for this model to get more stable/drop less tool calls, otherwise your work on the APEX models has helped me massively getting this running on just 8gb vram

Models did not require updating though, llama.cpp needed fixing, which is understandable. With every new model release takes a few days or a week to iron out quirks and bugs.

EDIT: it seems Unsloth had to update tokenizers yesterday due to this https://github.com/ggml-org/llama.cpp/pull/21343 so most likely applies to imatrix quants only?
