v0.4.1

New Features

• Added a CATCHUP_RECENT mode that allows a node to fetch the last N ledgers when joining the network.
• Added checkquorum command. Check quorum intersection from history.
• Added graphquorum command. Print a quorum set graph from history.
• Added inferquorum command. Print a quorum set inferred from history.

Fixes

• Reworked history system. Interface to the world is the same but it should work much better than before.
• Changed the definition of quorum slice to not need to include yourself. Your node is no longer automatically added to your quorum set.

v0.4.0

New features

• New meta data emitted (previous ledger entry state) - see #944
• Perform maintenance on startup by default for nodes not in CATCHUP_COMPLETE mode (this reduces the disk space requirement for those nodes as data is purged more often)- see #947
• Additional QUORUM_SET validation - as described in f9286a6 and fa048e6

Fixes and improvements

• Major history publish/download overhaul, to improve reliability of interactions with history subsystem - see #951
• Validators only forward messages from the extended quorum - this closes a potential attack vector to DoS validators
• Avoid triggering catchup from history when restarting a node after a short downtime
• Improved "quorum" reporting

v0.3.3

• Fix bug causing catch up to get stuck
• Better insight into what SCP is doing
• Better logs for debugging

v0.3.2

fix: crash in SCP when receiving some v-blocking CONFIRM

v0.3.1

Snap implementation of SCP to the version dated November 17 2015

v0.3.0

Rev SCP implementation to the latest version of the whitepaper (November 2015)

Note: this version is not compatible with the 0.2.X series but will still be able to replay history

v0.2.5

• bug fix in overlay (better handshake)
• ability to query all known peers for quorum information when using short node ID
• PREFERRED_PEERS now should work as expected
• scp command now returns quorum sets as well
• Extra documentation for running validators

v0.2.4

• Fixed edge case when receiving old SCP messages from peers that would cause nodes to crash
• Changed the way pending transactions are expired (especially important for non validating nodes)
• Config files are now parsed properly, this fixes an issue with the way node names are tracked
  • note: "self" is not populated automatically anymore, you need to create the alias yourself when defining the NODE_SEED element.

v0.2.3

-fixes crash introduced in v0.2.2
-better able to rejoin network
-adds /quorum that gives information on the state of yours or others quorums
-easier to determine health of the network

v0.2.2

Fixed crash when rejoining network
Fixed potential bucketlist corruption when rejoining network
forcescp works again
