- keytrans: Simplify the top-level API

- Use CDSI enclave 3a1ac5e5 in staging.

v0.89.2

- Expose getUploadForm() to clients (for attachments)

- A 508 response when connecting to a Signal service will result in backoff for reconnect attempts on all routes, not just the one that reached the server.

v0.89.0

- Node: Implementing `IdentityKeyStore.getIdentityKeyPair()` can avoid
  rederivation of the public key from the existing
  `IdentityKeyStore.getIdentityKey()` requirement. In the future, the
  PrivateKey-only `getIdentityKey()` will be removed.

- Node: Update all uses of `Uint8Array` and `Buffer` to use `ArrayBuffer`

- Expose `UnauthKeysService.getPreKeys()` to client libraries

- The `disableNagleAlgorithm` remote config flag has been removed, as the experiment has been deployed successfully.

- keytrans: Improve monitor_and_search logic to handle a wider set of scenarios (keep monitoring unchanged mappings, while falling back to search for the rest).

- Windows: revert change to build without build without `+crt-static`

v0.88.1

- backups: Add hasSeenAdminDeleteEducationDialog field support.

- backups: Support access control for member labels.

- java: Classify `ChatServiceInactive` errors as `RequestResult.RetryableNetworkError`

- Populate User-Agent and other headers for gRPC chat requests.

- Java: `SealedSessionCipher.encrypt(SignalProtocolAddress,
  SenderCertificate, byte[])` now throws `NoSessionException` instead
  of `AssertionError` when there's no usable 1:1 session with the
  given recipient. `encrypt(SignalProtocolAddress,
  UnidentifiedSenderMessageContent)` is not affected.

- Add "grpc.MessagesAnonymousSendMultiRecipientMessage" remote config,
  and the implementation backing it.

v0.87.5

- SPQR: upgrade to v1.5.0.

- Treat HTTP/2 transport errors disinct from gRPC status

- backup: Support iOS specific settings in account data.

v0.87.4
