JRomManager v2.4.0 Changelog:
Added full server mode
Made for an usage over the Internet (but it should be kept legal between users)
Jetty is used instead of NanoHTTPd
Multi-user with access rights, a per user WorkDir, a shared read-only space, and no access to the rest of the entire FileSystem
Totally secured (separate accounts with login/password, HTTPS with TLS 1.3, server certificate handling and auto reload, obfuscated paths, ...)
HTTP2 support (only with TLS 1.2) which permit long polling request usage in place of WebSockets without loosing too much network performance
This mode is still experimental, work still need to be made on disk/thread quotas, and a firewall with IP filtering may be required to get full control on who is attempting to connect
Implemented Long polling Request as alternative of WebSockets for simple server mode
New "Single File" mode, made for single ROM per game sets than can be kept in base directory without creating a sub-directory for each game...
Added support for import/export of settings from one profile to another
More graphical icons for tabs and buttons
Various fixes
This will be the last version supporting Java 8, next one will require at least Java 11
