<Update label="v0.2.0" description="15 Sept 2026">
  `breaking`

  Removed the multi-update subscription action. Autumn's endpoint accepts every request and applies nothing, so the action could only ever report success without cancelling or uncancelling anything — use the single subscription update action instead, once per subscription.

<Update label="v0.1.3" description="11 Sept 2026">
  `description-fix`

  Clarified that plan and feature identifiers must be IDs rather than display names and that a feature's label should be resolved with a lookup first, documented that recalculating balances on delete also requires a feature ID, mirrored the refund and proration mutual-exclusion rules onto the multi-update preview, noted that tiered credit schemas must be configured in the Autumn dashboard and that a reset interval is ignored on continuous-use features, and distinguished the single-record and list read actions.

<Update label="v0.1.2" description="7 Sept 2026">
  `guide-changes`

  Added the Autumn dashboard URL to the API Key connection guide, corrected the Secret Key field description to point to Developer > API Keys and the environment switcher, and removed the external support link so the Connection guide button opens the StackOne guide.
</Update>

<Update label="v0.1.1" description="4 Sept 2026">
  `description-fix`

  Clarified action descriptions from MCP agent testing. create\_schedule now tells callers to reuse a fresh server timestamp (get\_or\_create\_customer's created\_at) for the first phase instead of guessing the current time; credit\_schema is required for credit\_system and rejected on ai\_credit\_system; track\_token\_usage.model\_id needs the models.dev provider/model form; proration requires both on\_increase and on\_decrease; import\_billing takes a plan id, not a display name; and a price needs exactly one of amount or tiers.

<Update label="v0.1.0" description="1 Sept 2026">
  `new-actions`

  Initial Autumn connector with 64 actions across billing, balances, customers, entities, plans, features, referrals, rewards, licenses, keys, invoices, and events. Live-tested against the Autumn sandbox. Added the API Key connection guide and inbound webhook events (Svix-delivered). Doc-audit fixes — plan\_id/new\_plan\_id/currency constraints and removal of the non-existent create\_plan version param, and added track\_token\_usage timestamp/overage\_behavior/async params; exposed optional start\_cursor on paginated lists; enforced default\_markup min via rules; removed deprecated create\_schedule preserve\_add\_ons param; fixed nested price amount/currency/tier types, batch\_track raw-array spread, create\_reward duration.length, and documented provider cross-field rules.
