OpnForm
OpnForm's fourth patch in a week fixes forms and quietly widens self-hosted telemetry.
A side-by-side editorial comparison of AcyMailing and Buttondown — release velocity, themes, recent moves, and the top alternatives to consider.
AcyMailing 11.1 gives subscribers their own tracking switch and fixes one-click unsubscribe.
After the 11.0 security rework and five quick patches, AcyMailing moved to 11.1. 11.1.0 added a front-end checkbox for every user to manage tracking preferences, replaced the date picker with the native HTML one, fixed one-click unsubscribe via the List-Unsubscribe header and hardened some custom fields. 11.1.1 makes emails from its sending service lighter, blocks HTML in custom field values, improves OAuth error messages and stores Gravity Forms list choices in entries.
Buttondown breaks its run of fix-only days with better LaTeX, tweet and Mermaid rendering
Buttondown is a newsletter platform shipping small daily batches. Late October added a country filter on the subscribers API and a Stripe payment trigger for automations; November 1 to 5 was fixes only, from a paywall teaser leak to plus signs breaking redirect URLs. The November 6 batch is the first with visible rendering work: LaTeX equations sized for phones with alt text, old tweets turned into proper embeds, and faster, restyled Mermaid diagrams.

Privacy and deliverability run through every release since July: optional IP collection, GDPR pixel tracking, anonymous statistics, and now user-controlled tracking and a working one-click unsubscribe. Security fixes keep appearing in minor releases.
Expect 11.1.x patches on roughly a two-week rhythm, with more privacy controls and integration fixes such as the Gravity Forms work.

The cadence is steady and the scope narrow: email rendering fidelity, editor modes and small API filters. The latest batch suggests attention is shifting toward technical writers whose newsletters carry equations, diagrams and embeds, an audience few newsletter tools serve well.
Expect more daily fix batches, with occasional rendering or API-filter additions; nothing in the feed points to a larger launch.
