 * We have improved the way the VM searches for trusted root certificates for

   these do not exist will it fall back on the builtin trusted root certificates.
   This behavior can be overridden on Linux with the new flags
-  --root-certs-file and --root-certs-cache. The former is the path to a file
+  `--root-certs-file` and `--root-certs-cache`. The former is the path to a file
   containing the trusted root certificates, and the latter is the path to a
   directory containing root certificate files hashed using `c_rehash`.
 
+* The VM now throws a catchable `Error` when method compilation fails. This
