+
+This release adds multiple Single Use Reply Blocks (SURBs) to allow arbitrarily-sized anonymized replies.
+At the moment this is turned off by default, but available for use by application developers.
+We will need to wait for network-requesters to upgrade to this new release, after which multi-SURB anonymization will become the default setting for the SOCKS proxy clients.

+The release also include some additional work for distributed key generation in the Coconut signing authority nodes.

-# Nym Sphinx Wasm Demo
-
-This example application demonstrates how to use WebAssembly to create Sphinx packets, in the browser, and forward them to a Nym gateway.
-
-## 🚴 Usage
-
-Build the WASM package for bundling:
-
-```
-wasm-pack build --scope nymproject --target no-modules
-```
-
-in the `clients/webassembly` directory (one up).
-
-Start the webpack dev server:
-
-```
-npm install         # set up dependencies
-npm run start       # starts a web server at http://localhost:8001
-```
-
-Check your dev console for output.
-
-### Rebuild after Rust source changes
-
-Install `wasm-pack`. Instruction are at the [Rust WASM tutorial](https://rustwasm.github.io/docs/book/game-of-life/hello-world.html). 
-
-`wasm-pack build --scope nymproject --target no-modules` in the `clients/webassembly` directory (one up) will rebuild the wasm package if you make changes to the Rust source. That will be automatically picked up (and reloaded, if need be) by the npm dev server.
