What is Mailu?
Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures
Mailu's 2024.06 branch shipped six pinned releases in October, each tied to a single issue. Three dealt with the resolver: handling the DNSSEC KSK rollover, then making the healthcheck fail on SERVFAIL, re-shipped once. Three were webmail: Roundcube 1.6.20, mitigations for the PHP2Shell CVEs, and then the patched PHP runtime. Late September releases fixed boolean settings that could not be turned off and stale webmail sessions after switching accounts via SSO.
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.

Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures
◆ Current state
Mailu's 2024.06 branch shipped six pinned releases in October, each tied to a single issue. Three dealt with the resolver: handling the DNSSEC KSK rollover, then making the healthcheck fail on SERVFAIL, re-shipped once. Three were webmail: Roundcube 1.6.20, mitigations for the PHP2Shell CVEs, and then the patched PHP runtime. Late September releases fixed boolean settings that could not be turned off and stale webmail sessions after switching accounts via SSO.
◆ Where it's heading
The project remains in one-fix-per-release maintenance on the 2024.06 line, with upstream webmail and PHP security driving much of the cadence. Nothing in the entries points to a new main release.
◆ Prediction
The next releases will most likely follow upstream Roundcube or PHP security fixes, as three of the last six did.
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.
