Gumloop ships Gumball, background subagents, and a model router in two weeks—each one changes how agents work.
Gumloop has moved from a workflow automation platform to a multi-agent system with increasingly autonomous capabilities. In early September, the product introduced Gumball—a self-improving, proactive agent running on company infrastructure—background subagents that execute concurrently without blocking the main chat, and a Model Router that picks the right model per task automatically. These are not incremental additions; they represent a shift from 'automations you configure' to 'agents that improve themselves and manage their own execution resources.'
Keila v0.30.3 adds Liquid template caching for measurably faster campaign renders on large lists.
Keila is a steady open-source email newsletter platform built on Elixir/Phoenix, shipping incremental quality improvements. v0.30.3 (the most recent release) adds campaign ID as a template variable, introduces TLS/STARTTLS and SMTP authentication environment variables for system mailer configuration, adds Liquid template caching (described as a significant render performance improvement for large campaigns), and accelerates several queries across large projects.

These are not incremental additions; they represent a shift from 'automations you configure' to 'agents that improve themselves and manage their own execution resources.'
The self-improvement loop is the defining arc: Gumball learns from corrections, agents can now manage their own evaluation criteria, and the Model Router removes model selection as a user responsibility. The daily intelligence layer (Daily Chew, Gumball) is getting tighter with Highlights and actionable briefs. Gumloop is building toward autonomous contributors—proactive, self-assessing, and model-aware—rather than user-triggered task runners.
The next move is likely deeper agent-to-agent orchestration—routing work between Gumball and specialized subagents based on task type—or expanding the self-improvement loop to cover skill acquisition from past successful runs.

Keila's recent releases — v0.30.0's transactional email API, v0.20.0's new email scheduler, and now v0.30.3's performance work — show a project that is consolidating its architecture before broadening its feature set. The self-hosting focus remains; the additions to system mailer configurability suggest the project is listening to operators running Keila in production with non-standard SMTP setups.
Transactional email capabilities from v0.30.0 will likely expand — more API endpoints, webhook delivery events, or better unsubscribe handling for transactional vs. campaign messages. Performance tooling for large lists will continue as the Liquid caching work surfaces the right optimization targets.
