* Remove support for `ArrayBuffer` in unstable MSC3089 `createFile()` and `createNewVersion()` and instead use same content types as handled by `MatrixClient.uploadContent()`. This enables support for Node.js. ([\#2014](https://github.com/matrix-org/matrix-js-sdk/pull/2014)). * Support for password-based backup on Node.js ([\#2021](https://github.com/matrix-org/matrix-js-sdk/pull/2021)). * Add optional force parameter when ensuring Olm sessions ([\#2027](https://github.com/matrix-org/matrix-js-sdk/pull/2027)). * Fix call upgrades ([\#2024](https://github.com/matrix-org/matrix-js-sdk/pull/2024)).
