-STBLOCKPROFILE
-    Write block profiles to ``block-$pid-$timestamp.pprof`` every 20 seconds.
-
-STCPUPROFILE
-    Write a CPU profile to ``cpu-$pid.pprof`` on exit.

-STDEADLOCKTIMEOUT

 STLOCKTHRESHOLD

-STGUIADDRESS
-    Override GUI listen address.  Equivalent to passing :option:`--gui-address`.
-
-STGUIAPIKEY
-    Override the API key needed to access the GUI / REST API.  Equivalent to
-    passing :option:`--gui-apikey`.
-
-STGUIASSETS
-    Directory to load GUI assets from. Overrides compiled in assets. Useful for
-    developing webgui, commonly use ``STGUIASSETS=gui bin/syncthing``.
-
-STHEAPPROFILE
-    Write heap profiles to ``heap-$pid-$timestamp.pprof`` each time heap usage
-    increases.
-
-STNODEFAULTFOLDER
-    Don't create a default folder when starting for the first time. This
-    variable will be ignored anytime after the first run.  Equivalent to the
-    :option:`--no-default-folder` flag.
-
-STNORESTART
-    Equivalent to the :option:`--no-restart` flag.
-
-STNOUPGRADE
-    Disable automatic upgrades.  Equivalent to the :option:`--no-upgrade` flag.
-
-STPROFILER
-    Set to a listen address such as "127.0.0.1:9090" to start the profiler with
-    HTTP access, which then can be reached at
-    http://localhost:9090/debug/pprof. See ``go tool pprof`` for more
-    information.
-
-STPERFSTATS
-    Write running performance statistics to ``perf-$pid.csv``. Not supported on
-    Windows.
-
-STRECHECKDBEVERY
-    Time before folder statistics (file, dir, ... counts) are recalculated from
-    scratch. The given duration must be parseable by Go's ``time.ParseDuration``. If
-    missing or not parseable, the default value of 1 month is used. To force
-    recalculation on every startup, set it to ``1s``.
-
-STGCINDIRECTEVERY
-    Sets the time interval in between database garbage collection runs.  The
-    given duration must be parseable by Go's ``time.ParseDuration``.
+STVERSIONEXTRA
+    Add extra information to the version string in logs and the version line
+    in the GUI. Can be set to the name of a wrapper or tool controlling
+    syncthing to communicate this to the end user.
