 ## changes in this version
 
+* Core:
+    * Added Initial Support to GoToSocial.
+    * The translation module has been rewritten. Now, instead of offering translations with Google Translator, the user can choose between [LibreTranslate,](https://github.com/LibreTranslate/LibreTranslate) which requires no configuration thanks to the [instance of the NVDA Spanish community;](https://translate.nvda.es) or translate using [DeepL,](https://deepl.com) for which it is necessary to create an account on DeepL and [subscribe to a DeepL API Free plan](https://support.deepl.com/hc/en-us/articles/360021200939-DeepL-API-Free) to obtain the API key which can be used to translate up to 500000 characters every month. The API key can be entered in the global options dialog, under a new tab called translation services. When translating a text, the translation engine can be changed. When changing the translation engine, the target language must be selected again before translation takes place.
 * Mastodon:
     * Fixed an error that caused TWBlue to be unable to properly display the user action dialog from the followers or following buffer. ([#575](https://github.com/mcv-software/twblue/issues/575))
