n8n
n8n 3.0 is out, shipped the same morning as 2.46 after weeks of migration-report groundwork.
A side-by-side editorial comparison of Keila and SendPortal — release velocity, themes, recent moves, and the top alternatives to consider.
Keila v0.30.3 adds Liquid template caching for measurably faster campaign renders on large lists.
Keila is a steady open-source email newsletter platform built on Elixir/Phoenix, shipping incremental quality improvements. v0.30.3 (the most recent release) adds campaign ID as a template variable, introduces TLS/STARTTLS and SMTP authentication environment variables for system mailer configuration, adds Liquid template caching (described as a significant render performance improvement for large campaigns), and accelerates several queries across large projects.
SendPortal resurfaces with a v4 patch release, its first tag since 2020.
SendPortal's last tagged release before this month was v1.0.3 in July 2020. On October 22 it published v4.0.0.1, which fixes sp:install skipping migrations on fresh installs and a route-caching failure from a duplicate logout route. The changelog link implies a v4.0.0 release just before it, which isn't in the tracked entries.

Keila's recent releases — v0.30.0's transactional email API, v0.20.0's new email scheduler, and now v0.30.3's performance work — show a project that is consolidating its architecture before broadening its feature set. The self-hosting focus remains; the additions to system mailer configurability suggest the project is listening to operators running Keila in production with non-standard SMTP setups.
Transactional email capabilities from v0.30.0 will likely expand — more API endpoints, webhook delivery events, or better unsubscribe handling for transactional vs. campaign messages. Performance tooling for large lists will continue as the Liquid caching work surfaces the right optimization targets.

A major version followed by fixes to the installer suggests the project is active again and new installs are being tested. With two tagged releases six years apart, there's no cadence to read yet.
If v4 is a real revival, more point releases should follow within weeks; another long silence would mean v4 was a one-off.
