Ollama: Hardening Pass Across Network, Memory, and Release Paths

This is Ollama, your daily briefing for September 18th, 2026.
The clearest pattern today: the team is hardening systems that quietly handle trust and resources in the background, where failures are expensive and hard to spot.
Start with security. PR 18512 from Patrick Devine tightens how registry and blob transfers follow redirects. The system now validates the target scheme and re-resolves DNS on every redirect, and it refuses to let a secure session get silently downgraded to plain HTTP. The insecure flag still relaxes address checks…
Next, memory. Jesse Gross's fix, commit E-C-3-C-C-2-3, targets the MLX runner's handling of speculative decoding. The buffer pool was only getting released when the token count landed exactly on a multiple of 256 — fine for normal decoding, but speculative decoding jumps past that boundary most rounds. The result…
Third theme: release reliability. Daniel Hiltgen's PR 18516 responds to flaky GitHub Actions uploads by serializing final release jobs, deleting stale assets before retagging, and adding retries with backoff for uploads and cleanup. The checksum manifest now only goes out after every payload succeeds — reducing the…
On the product side,…
