* Fixes #6221 - C3 hang on `import wifi`. Enabling the WiFi PHY was disabling USB. Now boards that use it set CONFIG_ESP_PHY_ENABLE_USB explicitly. * Fixes #6655 - Allows pasting into the web serial page. Fixes reading more than 0xf bytes at a time. * Fixes #6653 - Fixes web socket encoding of payloads >125 bytes. Can happen when printing a long string. * Fixes C3 responsiveness when waiting for key to enter REPL. (It now correctly stops sleeping.) * Disables title bar updates when in raw REPL. Related to #6548. * Adds version to title bar.
