Bug
Fixes
and
Download
Instructions

This
release
addresses
a
packing
pool
bug
where
all
transactions
had
the
same
price.
Node
operators
and
miners
can
download
the
new
version
from
the
official

GitHub
repository.

For
node
operators,
it
is
crucial
to
upgrade
to
the
latest
version
before
the
epoch
number
reaches
175600000.
Failure
to
do
so
will
result
in
nodes
being
incompatible
with
the
upgraded
Conflux
protocol,
affecting
functionalities
such
as
block
synchronization
and





mining.

For
new
nodes,
the
latest
Conflux
v2.4.0-testnet
version
is
recommended
for
installation.
