+- [#434] Added a system property to disable unsupported mod warnings
+    - Add `-Dloader.ignore_unsupported_mods=true` to your JVM arguments to disable them.
+- Tweaks to generated reports (usually crash reports):
+    - Include the zone offset (raw time number like +0100) in the actual crash report file.
+        This should help when assisting people in other timezones - as we can figure out if a crash report was generated just now, or is an older one.
+    - Change from CLOCK_HOUR_OF_DAY to HOUR_OF_DAY. This means we'll get digital time at 15 minutes past midnight (00:15) rather than analog time (24:15)
