Fourwaves follows its participant inbox with a week of admin fixes and security hardening.
A side-by-side editorial comparison of Eventzilla and Kamailio — release velocity, themes, recent moves, and the top alternatives to consider.
One real theme release amid stale event-planning content
Eventzilla's feed pairs a single product update — five new event-landing-page themes — with a backlog of evergreen event-planning strategy posts. The entries run from mid-2024 to March 2025, so the crawled feed is stale by more than a year.
Kamailio's feed shows quiet, migration-free upkeep across two stable branches.
Kamailio is a mature open-source SIP server, and its tracked releases are maintenance drops: v6.1.5 on the current 6.1 stable branch and, earlier, v5.8.7 on 5.8. Both carry fixes only, with no database schema or configuration language changes, and the project strongly recommends upgrading within each branch.

The lone product move is cosmetic (landing-page themes), and everything newer is absent, so the trajectory is not observable — the blog appears to have stopped updating or the crawler is on an archived feed.
Without recent entries, no confident prediction; the feed source likely needs re-pointing to confirm whether product work continues.
Kamailio is a mature open-source SIP server, and its tracked releases are maintenance drops: v6.1.5 on the current 6.1 stable branch and, earlier, v5.8.7 on 5.8. Both carry fixes only, with no database schema or configuration language changes, and the project strongly recommends upgrading within each branch.
The visible pattern is conservative branch upkeep: fixes land on more than one branch at once without forcing operators to touch configs or schemas. The feed does not show feature releases or capability shifts.
Expect further 6.1.x point releases on the same no-migration terms; the entries do not show when the next feature branch is due.
