What is Merge?
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
What is Umbrel?
umbrelOS now pins any Docker container to the home screen — the app store stopped being the boundary.
umbrelOS 1.7 shipped in late April with home screen Shortcuts pointing at websites, custom ports and Docker containers, a text editor built into Files, advanced networking controls, folder sharing from external drives and seventeen new languages. The three patches since have been split between its own bugs — storage error screens, Tor connectivity — and inherited Linux kernel vulnerabilities, with emergency updates for CopyFail in early May and DirtyFrag a week later.

Merge

Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
◆ Current state
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
◆ Where it's heading
The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
◆ Prediction
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.
Umbrel
2.5INFRA · APIS
umbrelOS now pins any Docker container to the home screen — the app store stopped being the boundary.
◆ Current state
umbrelOS 1.7 shipped in late April with home screen Shortcuts pointing at websites, custom ports and Docker containers, a text editor built into Files, advanced networking controls, folder sharing from external drives and seventeen new languages. The three patches since have been split between its own bugs — storage error screens, Tor connectivity — and inherited Linux kernel vulnerabilities, with emergency updates for CopyFail in early May and DirtyFrag a week later.
◆ Where it's heading
Umbrel is building a desktop metaphor on top of a personal server: 1.5 added encrypted backups, file history and GPU acceleration, and 1.7 adds shortcuts, a text editor and network shares. At the same time, shipping a full operating system means inheriting the kernel's vulnerability schedule, and two of the four releases in this window exist solely because of it. That is the ongoing cost of the model.
◆ Prediction
Expect the Files and home screen surfaces to keep absorbing desktop functionality, since that is where the last two feature releases have concentrated. Also expect the kernel CVE cadence to keep interrupting it — the two May releases arrived a week apart and neither was planned.
