What is mailcow?
mailcow's monthly releases are mostly upstream security updates with small UI work
mailcow ships named monthly releases with lettered revisions, and most exist to pull in upstream security fixes for components like SOGo, Nginx, Redis, Unbound and Rspamd. The September release also added an ACL and global switch to stop external alias forwarding, a show-password toggle on login pages, and fixes such as an auth-cache wipe during nginx outages. October moved PHP to an Alpine 3.24 base and brought SOGo 5.12.12, Nginx 1.30.6 and a UI update.
What is Subsplash?
Subsplash gives church staff notes on every person and every Workflow card.
Subsplash runs giving, media, people and workflow tools for churches. Late September brought notes on People profiles and Workflow cards, board search and hide-completed checklists in Workflows, gift totals and recurring-gift status in Giving, and timestamped share links for media. October added multi-select actions on People.

mailcow's monthly releases are mostly upstream security updates with small UI work
◆ Current state
mailcow ships named monthly releases with lettered revisions, and most exist to pull in upstream security fixes for components like SOGo, Nginx, Redis, Unbound and Rspamd. The September release also added an ACL and global switch to stop external alias forwarding, a show-password toggle on login pages, and fixes such as an auth-cache wipe during nginx outages. October moved PHP to an Alpine 3.24 base and brought SOGo 5.12.12, Nginx 1.30.6 and a UI update.
◆ Where it's heading
Keeping a dozen bundled upstreams current is the product, and the cadence is built around that. Feature work arrives in small admin and web UI controls alongside the security updates.
◆ Prediction
Expect a revision of the October release carrying further upstream updates, following the lettered-revision pattern.
Subsplash
2.5COMMS
Subsplash gives church staff notes on every person and every Workflow card.
◆ Current state
Subsplash runs giving, media, people and workflow tools for churches. Late September brought notes on People profiles and Workflow cards, board search and hide-completed checklists in Workflows, gift totals and recurring-gift status in Giving, and timestamped share links for media. October added multi-select actions on People.
◆ Where it's heading
The platform is filling in the record-keeping that church staff did in other tools: notes, handoffs, follow-ups and giving totals now live next to the person or card. Workflows keeps getting features for busy boards and team handoffs. The releases are practical and incremental rather than new product lines.
◆ Prediction
Expect Workflows and People to keep converging, for example notes or tasks shared between a person and their cards. The entries say nothing new about the AI features mentioned earlier in the year.
