 ## [Unreleased]
 
+### Added
+
+- Add `Eip1193Compatible` property in `KnownSessionProperties` enum to support EIP-1193-style connections established through `connect-evm` ([#8731](https://github.com/MetaMask/core/pull/8731))
+- Set `sessionProperties: { 'eip1193-compatible': true }` in `getCaip25PermissionFromLegacyPermissions` so that legacy EIP-1193 permission requests are tagged as EIP-1193-compatible ([#8731](https://github.com/MetaMask/core/pull/8731))
+
 ### Changed
 
 - Bump `@metamask/permission-controller` from `^12.2.1` to `^13.1.0` ([#8317](https://github.com/MetaMask/core/pull/8317), [#8661](https://github.com/MetaMask/core/pull/8661), [#8722](https://github.com/MetaMask/core/pull/8722))
