v1.4.7
Bug fix
⚠ Upgrade required
- Run `pip install --upgrade omega-memory` then execute `omega activate OMEGA-PRO-` to enable Pro features.
Full changelog
Fix: Pro activation works from bare omega-memory install
omega activate now works without requiring the Pro wheel to be pre-installed:
- Validates the license key directly against the activation API
- Auto-downloads and installs the Pro package
- Single command from install to fully working Pro
Previously, omega activate failed with "OMEGA Pro is not installed" because it required a package that only exists after Pro setup, creating a chicken-and-egg problem.
Upgrade
pip install --upgrade omega-memory
omega activate OMEGA-PRO-<your-key>
v1.4.6
