Subject: Ignore unknown Events serialized with an odd type value.
X-Git-Tag: v0.0.100~10^2~3

Ignore unknown Events serialized with an odd type value.

This should provide some additional future extensibility, allowing
for new informational events which can be safely ignored to be
ignored by older versions.
