## [0.1.0] - 2026-05-13

### Added
- Initial public release: Olm + Megolm primitives for Matrix
  end-to-end encryption, built on Element's
  [vodozemac](https://github.com/matrix-org/vodozemac) (Rust) via
  Rustler. Surface covers account / one-time-keys, inbound and
  outbound Megolm group sessions, Olm pairwise sessions, raw Ed25519
  + Curve25519 helpers, and SAS short-authentication-string
  verification.

### Known limitations
- **Source-only release.** Consumers need a Rust toolchain
  (`rustup install stable`) on `mix deps.get`; the NIF compiles
  from source via Rustler. Precompiled binaries for the four major
  macOS + Linux targets are scheduled for 0.1.1.
- Pickle bytes are wrapped with vodozemac's default zero-key — no
  confidentiality at rest. Callers must apply their own at-rest
  encryption until a `pickle_key` parameter lands in a later release.
