conjoon v2.0.0-alpha.0 was just released 🎉, offering a glimpse of what's to come with the upcoming 2.0 release.
The 2.0 release-branch is mainly focusing on achieving better compliance with the JSON:API-specifications that are documented in the rest-api-description available with the php-lib-conjoon#8-branch.
Pre-releases of extjs-app-webmail and extjs-dev-webmailsim are bundled with this version and demonstrate the changes backends should be expecting if they wish to provide communication endpoints for the webmail client.
Happy testing! ☃️
