We are pleased to release Litecoin Core 0.14.2 release candidate. This is a new major version release, including new features, various bug fixes and performance improvements.

After sufficient testing it is recommended for all users to upgrade to this version.

This only affects users that have explicitly enabled UPnP through the GUI setting or through the -upnp option, as since the last UPnP vulnerability (in Litecoin Core 0.10.4) it has been disabled by default.

If you use this option, it is recommended to upgrade to this version as soon as possible.
