What is AcyMailing?
AcyMailing 11.1 gives subscribers their own tracking switch and fixes one-click unsubscribe.
After the 11.0 security rework and five quick patches, AcyMailing moved to 11.1. 11.1.0 added a front-end checkbox for every user to manage tracking preferences, replaced the date picker with the native HTML one, fixed one-click unsubscribe via the List-Unsubscribe header and hardened some custom fields. 11.1.1 makes emails from its sending service lighter, blocks HTML in custom field values, improves OAuth error messages and stores Gravity Forms list choices in entries.
What is Gumloop?
Gumloop 13.4 trims agent tool use by about 40% and shows agents across all teams.
Gumloop ships a numbered release every few days. 13.0 rebuilt the agent harness for longer work, 13.2 added team Homes and App Rules for tool-call approval, and 13.3 let organizations publish agents to Okta. 13.4 gives agents a smaller core toolset plus one search over the rest, using about 40% fewer tokens per step, shows agents, triggers and artifacts across every team a user belongs to, and lets admins route the agent browser through their own proxy.

AcyMailing
2.5MKT AUTO
AcyMailing 11.1 gives subscribers their own tracking switch and fixes one-click unsubscribe.
◆ Current state
After the 11.0 security rework and five quick patches, AcyMailing moved to 11.1. 11.1.0 added a front-end checkbox for every user to manage tracking preferences, replaced the date picker with the native HTML one, fixed one-click unsubscribe via the List-Unsubscribe header and hardened some custom fields. 11.1.1 makes emails from its sending service lighter, blocks HTML in custom field values, improves OAuth error messages and stores Gravity Forms list choices in entries.
◆ Where it's heading
Privacy and deliverability run through every release since July: optional IP collection, GDPR pixel tracking, anonymous statistics, and now user-controlled tracking and a working one-click unsubscribe. Security fixes keep appearing in minor releases.
◆ Prediction
Expect 11.1.x patches on roughly a two-week rhythm, with more privacy controls and integration fixes such as the Gravity Forms work.
Gumloop
7.5MKT AUTO
Gumloop 13.4 trims agent tool use by about 40% and shows agents across all teams.
◆ Current state
Gumloop ships a numbered release every few days. 13.0 rebuilt the agent harness for longer work, 13.2 added team Homes and App Rules for tool-call approval, and 13.3 let organizations publish agents to Okta. 13.4 gives agents a smaller core toolset plus one search over the rest, using about 40% fewer tokens per step, shows agents, triggers and artifacts across every team a user belongs to, and lets admins route the agent browser through their own proxy.
◆ Where it's heading
After expanding what agents can reach, Gumloop is now working on cost, speed and admin control for organizations running many agents. Slack agents that answer every channel message push them further into always-on roles.
◆ Prediction
More enterprise controls are likely next: proxy, registry and approval features suggest deeper identity and network policy, plus further token-cost cuts.
