Relay 2.6.0

Relay could not update itself. That is fixed.

Updates now actually happen

Every piece of the update path existed already — check GitHub, compare versions,
download, verify the checksum, run the installer — and nothing called any of it.
On Windows that machinery had been sitting unused since 2.2, so if you installed
Relay once you stayed on that version forever while the README told you updates
were offered. On Android the in-app update banner has never appeared for anyone,
because the check behind it had no callers at all.

On Windows, Relay now updates itself. It looks a couple of minutes after
launch and then once a day, tells you what it found, and installs it the next
time your tunnel is down. It will not interrupt a connection: installing means
stopping Relay, and doing that mid-call would drop the call. It closes, updates,
and comes back on its own.

On Android, Relay tells you and offers it. It checks when you open the app
and also when sharing starts — so if you only ever use the Quick Settings tile or
the home screen widget, you still find out. Android does not allow a sideloaded
app to install anything silently, so the final tap is always yours. That is a
platform rule, not a choice we made.

Either way, nothing is installed that was not verified byte-for-byte against the
SHA256SUMS.txt published in that same release. A download that fails the check
is deleted, not kept. Relay carries your whole connection, so replacing itself
has to mean replacing itself with exactly what was published.

Upgrading to this one

This is the last release you have to install by hand on Windows. From here
Relay keeps itself current.

Download below, or from the buttons in the
README. Windows will warn on
first run because the installer is not code-signed yet — More info → Run
anyway. On Android, take arm64-v8a unless it says the app is not compatible,
in which case take universal.

Everything in 2.5.0 — the DNS and IPv6 leak fixes, and the speed regression —
is included.
