v2.11.46 New feature 1mo

Notable features

Structured JSON logging available through --log-format=json or ONWATCH_LOG_FORMAT=json

Full changelog

What's New

Structured JSON logging (#70)

You can now switch log output from the default key=value text format to JSON via CLI flag or environment variable:

# CLI flag
onwatch --log-format json

# Environment variable
ONWATCH_LOG_FORMAT=json onwatch

JSON output uses Go's native slog.JSONHandler, producing machine-readable logs ideal for container logging pipelines (Fluentd, Loki, CloudWatch, etc.).

Accepts aliases: text, txt, fmt for text format; json for JSON
Case-insensitive input
Works in all modes: background, --debug, --debugstdout, and Docker
Defaults to text if unset or unrecognized

Bug Fix

Codex Team/Business workspace token cross-contamination (#69)

When multiple users from the same ChatGPT Team or Business workspace saved profiles, they shared the same account_id. The system credentials fallback only checked account_id match when picking up tokens from ~/.codex/auth.json - so one user's tokens would silently overwrite the other profile, causing both to poll with the same identity and show identical usage data.

The fallback now also checks user_id, rejecting system credentials that belong to a different user on the same workspace.

After updating, re-save your profiles to restore correct tokens:

# Log into first account
codex auth
onwatch codex profile refresh <profile1>

# Log into second account  
codex auth
onwatch codex profile refresh <profile2>

Menubar Improvements

Auto-save settings - changes apply immediately, no manual Save needed
Fixed menubar showing stale data - companion now fetches from the main daemon instead of building its own snapshot
New providers auto-visible - newly added providers appear in menubar without manual configuration
