Gumloop 13.6 gives admins one set of rules for every tool an agent touches.
Gumloop ships a numbered release every few days. 13.0 rebuilt the agent harness, 13.3 published agents to Okta, 13.4 cut agent tokens per step by about 40% and 13.5 added live multi-user tasks. 13.6 extends admin guardrails from connectors to every tool, redacts card numbers and passwords before models see them, warns when agent instructions contain credentials, adds browser allow and block lists and domain-restricted API keys, and introduces Workforce Atlas, a board of every agent and skill in the organization.
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.

Since 13.2 the releases have moved from what agents can do toward how a company controls them. 13.6 is the broadest step yet: approval rules, data redaction and secret handling now cover all agent activity, which is what security teams ask for before a wide rollout.
Expect Workforce Atlas to leave beta with more tags and reporting, and more enterprise controls such as audit exports built on the new guardrail records.

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.
