The subscription button read the source and applied nothing, so fresh servers
existed only in its report while the table kept the previous count. That read as
lost servers rather than as work not yet done. The button now applies what it
downloads; checking without applying stayed in the context menu, where it says
so.
The sing-box Extended core only ever arrived with a build of the application, so
a fix in the core had to wait for the next Zapret KVN release. The updates page
offers it the same way it offers Xray: show the installed version, look up the
newest release, and replace the executable only on an explicit action. Its tag
carries two versions — the core and the extension set — and both are compared,
otherwise an update within the same core version would go unnoticed. A release
that cannot be read is never treated as newer, and an archive without the
executable leaves the previous core in place.
