Community contributors: @pierre427 — DeepSeek-V4 explicit YaRN attention_factor (#1225) and containing local model_file imports to the model root (#1226).

Live KV-cache quantization now engages on vision models too. The --kv-cache-dtype int8/int4 path probes the nested language-model head_dim, so multimodal servers get the same steady-state KV savings as text models; a fail-safe keeps bf16 wherever no supported group size fits (PR #1208, #1231).
Qwen3.6-35B-A3B serves coherently again. An upstream mlx-lm change had applied a spurious +1.0 RMSNorm shift that garbled this checkpoint; it is now undone (PR #1234).
MTP no longer returns intermittent empty responses. The Qwen3.6 MTP sidecar path could occasionally emit nothing; sidecar extraction and eligibility checks were hardened (PR #1201, #1214, #1215).
A quieter, clearer first run. Cold-model downloads show a TTY-aware single-line progress bar with the correct starter size; the unauthenticated-download advisory and leaked Hugging Face progress bars are silenced; and cold-start dead air is gone (PR #1237, #1259, #1260, #1263).
MCP config accepts the standard mcpServers key. Following the standard examples previously resolved to zero servers; the standard key is now honored (PR #1243).
Output-coherence release gate. Six blocking golden checks plus an advisory garbage detector now guard every release across the model fleet (PR #1247, #1262).
