# Changelog

Every release of the package, newest first.

## 0.0.1

The first release. It has a Go twin for every method of the TypeScript SDK, in the same namespaces, and needs Go 1.24 or later and nothing outside the standard library.

- `openemail.New()` reads `OPENEMAIL_API_KEY`, `OPENEMAIL_ACCESS_TOKEN` and `OPENEMAIL_BASE_URL`, and takes options such as `WithAPIKey`, `WithBaseURL`, `WithHTTPClient`, `WithTimeout` and `WithMaxRetries`.
- Every failure is an `*openemail.Error`, matched with `errors.Is` against sentinels such as `ErrNotFound`, `ErrValidation` and `ErrRateLimited`.
- `openemail.VerifyWebhookSignature()` checks a delivery, and `openemail.NewTempMail()` builds a client for disposable inboxes.
- A sign-up form field can fill more of the contact: `mapsTo` also takes `phone`, `company`, `jobTitle`, `website` and `birthday`, saved on the contact card when the sign-up is accepted and only where the card has nothing yet. A single contact now comes with `signUps`, its last 20 sign-ups with their answers, for a caller that holds `forms:read`.
