Blocker
A release blocking bug is a bug which is judged severe
enough to justify blocking release until it is fixed.
Blocker bugs generally violate a release criterion
(
alpha,
beta,
final)
and follow the
blocker SOP.
Freeze Exception
Freeze exception bugs are generally not possible to fix
with an update after release but do not qualify as
release blocking. Freeze exception bugs follow the
freeze exception SOP.
