Why

The changelog hasn't been updated since 1 September.

How

Candidates were taken from every commit merged to main in the window. Each one was checked against its diff, and the final selection was confirmed by hand. Items were left out on purpose for these reasons:

• Behind a feature flag: config as code and agent payments.
• Only in the unreleased 2027-01 API: external IDs and the credit API endpoints.
• Held for a separate launch: Polar CLI 2.0/3.0.
• Not included this time: the API version 2026-10 switch, portal quantity changes, and product deletion.

The new block contains no em or en dashes and doesn't name the payment processor.

Checklist

• This PR addresses a single concern (one bug fix, one feature, one refactor)
• The diff is reasonably sized and easy to review
• New functionality is covered by tests (docs only)
• Linting and type checking pass (docs only, not applicable)
• No unrelated changes or drive-by fixes are included

<sub>Auto-approved: Adds a text-only changelog entry documenting already-shipped usage-billing and invoice features, plus supporting docs-only updates; no code or product behavior changes, so remaining risk is ordinary documentation accuracy.
