Mining
------
Getblocktemplate sets the segwit version bit even when the downstream
client has not been updated to include the segwit commitment. Ability
to enforce the rule is the only required criteria for safe activation,
but previously signaling was only requested if the miner could include
transactions in order to avoid a potential outcome where segwit would
activate at a time when no segwit transactions could be included.
Since many miners are now including the segwit commitment this concern
no longer applies.
In previous versions, getblocktemplate required segwit support from downstream
clients/miners once the feature activated on the network. In this version, it
now supports non-segwit clients even after activation, by removing all segwit
transactions from the returned block template. This allows non-segwit miners to
continue functioning correctly even after segwit has activated.
Due to the limitations in previous versions, getblocktemplate also recommended
non-segwit clients to not signal for the segwit version-bit. Since this is no
longer an issue, getblocktemplate now always recommends signalling segwit for
all miners. This is safe because ability to enforce the rule is the only
required criteria for safe activation, not actually producing segwit-enabled
blocks.
