flag and config variable. See ADR-52 @dongsam - [rpc] #6329 Don't cap page size in unsafe mode (@gotjoshua, @cmwaters)
- [pex] #6305 v2 pex reactor with backwards compatability. Introduces two new pex messages to accomodate for the new p2p stack. Removes the notion of seeds and crawling. All peer exchange reactors behave the same. (@cmwaters)
- [crypto] #6376 Enable sr25519 as a validator key
- [mempool] #6466 Introduction of a prioritized mempool. (@alexanderbez)
Priority
andSender
have been introduced into theResponseCheckTx
type, where thepriority
will determine the prioritization of the transaction when a proposer reaps transactions for a block proposal. Thesender
field acts as an index.- Operators may toggle between the legacy mempool reactor,
v0
, and the new prioritized reactor,v1
, by setting themempool.version
configuration, wherev1
is the default configuration. - Applications that do not specify a priority, i.e. zero, will have transactions reaped by the order in which they are received by the node.
- Transactions are gossiped in FIFO order as they are in
v0
.

time_iota_ms
consensus parameter, to reduce the bug surface. The parameter is no longer used. (@valardragon) - [store] #5888 store.SaveBlock saves using batches instead of transactions for now to improve ACID properties. This is a quick fix for underlying issues around tm-db and ACID guarantees. (@githubsands)
- [consensus] #5987 Remove
time_iota_ms
from consensus params. Mergetmproto.ConsensusParams
andabci.ConsensusParams
. (@marbar3778) - [types] #5994 Reduce the use of protobuf types in core logic. (@marbar3778)
ConsensusParams
,BlockParams
,ValidatorParams
,EvidenceParams
,VersionParams
,sm.Version
andversion.Consensus
have become native types. They still utilize protobuf when being sent over the wire or written to disk.
