+- Add the `sqlite` feature, along with the `indexeddb` feature, to enable
+  either the SQLite or IndexedDB session store. The `session_paths`,
+  `session_passphrase`, `session_pool_max_size`, `session_cache_size` and
+  `session_journal_size_limit` methods on `ClientBuilder` have been removed.
+  New methods are added: `ClientBuilder::session_store_in_memory` if one wants
+  non-persistent session storage, `ClientBuilder::session_store_with_sqlite` to
+  configure and to use SQLite as the session store (if the `sqlite` feature is
+  enabled), and `ClientBuilder::session_store_with_indexeddb` to configure and
+  to use IndexedDB as the session store (if the `indexeddb` feature is enabled).

 - Add `Room::mark_as_fully_read_unchecked` so clients can mark a room as read without needing a `Timeline` instance. Note this method is not recommended as it can potentially cause incorrect read receipts, but it can needed in certain cases.
 - Add `Timeline::latest_event_id` to be able to fetch the event id of the latest event of the timeline.

 This uses [`uniffi`](https://mozilla.github.io/uniffi-rs/Overview.html) to build the matrix bindings for native support and wasm-bindgen for web-browser assembly support. Please refer to the specific section to figure out how to build and use the bindings for your platform.
 
 ## Features
+
 Given the number of platforms targeted, we have broken out a number of features
 
-### Platform specific 
+### Platform specific
+
 - `rustls-tls`: Use Rustls as the TLS implementation, necessary on Android platforms.
 - `native-tls`: Use the TLS implementation provided by the host system, necessary on iOS and Wasm platforms.
 
 ### Functionality
+
 - `sentry`: Enable error monitoring using Sentry, not supports on Wasm platforms.
-- `bundled-sqlite`: Use an embedded version of sqlite instead of the system provided one.
+- `sqlite`: Use SQLite for the session storage.

 ### Unstable specs

 - `unstable-msc4274`: Adds support for gallery message types, which contain multiple media elements.
 
 ## Platforms
 
-Each supported target should use features to select the relevant TLS system.  Here are some suggested feature flags for the major platforms:
