# Changelog



## [0.2.0] - 2026-08-31



### Changed

- Default Graph API version is now `v26.0` (was `v2.6`, which expired in 2018).

  See https://developers.facebook.com/docs/graph-api/changelog/versions/

- Require Elixir 1.14+ and replace Poison with Jason.

- Upgrade HTTPoison to 2.x. HTTP options are now read at runtime.

- Replace `:crypto.hmac/3` (removed in OTP 24) with `:crypto.mac/4`.

- Parse Graph API error objects (`message`, `type`, `code`, `error_subcode`, `fbtrace_id`)

  instead of returning a generic "not found resource" message.

- Treat HTTP 2xx as success so create calls that return 201 work.

- Preserve batch response order (previously reversed).

- Encode batch POST bodies with `&` instead of `&`.

- Send video uploads to `graph-video.facebook.com`.

- POST/DELETE GenServer methods now use `call` so callers receive the API response.

  `handle_cast` previously returned `{:reply, ...}`, which crashes a GenServer.

- Replace Dogma with Credo. Drop inch_ex.



### Added

- `Exfacebook.Api.meet_challenge/2` for Webhooks verification requests.

- `Exfacebook.Api.appsecret_proof/1`.

- Configurable `graph_url` and `graph_video_url`.



### Security

- Stop logging access tokens and app secret proofs.

- Move app credentials out of shared `config/config.exs`.
