Option B: Upgrade from Version 08

pip install --upgrade agent17
agent17 migrate --from v08 --to v09-new

The migration tool will convert your old memory vectors and configuration files automatically. Backups are recommended.

Time Management Adjustments

Version 0.9 introduces a "slow time" toggle instead of a full pause. You can now stretch a minute into three, but you cannot freeze time entirely. This raises tension during stealth sections while still allowing strategic thinking.

Criticisms

4.3 Improved Logging

JSON structured logs now include trace IDs, making it easier to debug long agent runs with tools like jq or Loki.

4. User Interface and Configuration Improvements

For those running the optional Web UI or using the REST API, several quality-of-life updates have landed:

Data Flow (short)

  1. API receives request → Planner creates Task with subtasks.
  2. Sandbox Executor runs simulated subtasks (no side effects) and produces a dry-run result.
  3. If configured auto-approve, Real Executor runs; otherwise, requires admin approval via Admin Console.
  4. Telemetry Collector records spans and events; Task DB records states.
