The ggml‑org/llama.cpp project released a new version on 2026-10-08. The update adds support for the classifier_activation parameter used by reranker models. It also maps the classifier GELU activation to GELU_ERF, accepts tanh, and sets tanh as the default classifier activation, with ModernBERT falling back to GELU_ERF.

## The facts

- Release date: 2026-10-08
- Adds classifier_activation support for rerankers

## Why it matters

Developers can now fine‑tune reranker models more easily, potentially improving search relevance.
