log4j2.properties now has debugging entries removed.
log4j2-test.properties (not in repo) takes priority
so using that in development instead.
Unconfirmed transactions no longer wiped on start-up
by default - see Settings
Reworking of {Public,Private,Genesis}Accounts as it seemed
possible to silently lose public key in repository.
The use of AccountData didn't work and so field-specific
repository calls have been made instead
(e.g. setLastReference) that try to opportunistically
store public key too, if available (i.e. caller is
PublicKeyAccount subclass, or better).
Added API call GET /addresses/{address} to return
general account info in one go. (Essentially the
AccountData object as fetched from repository).
Initial work on adding default groupID to accounts,
along with corresponding SET_GROUP transaction type.
In additional, added blockchain-wide default groupID
and flag to allow/disallow no-group/groupless
transactions.
Initial work on group-admin approval of transactions
tied to a specific group via txGroupId.
More work needed on transaction's "effective txGroupId"!
API call /transactions/pending to list transactions
pending group-admin approval. However, this needs more
work (see effective txGroupId above) and potentially
offloading to HSQLDB repository if possible.
Minor CIYAM AT renames to help static reflection initializers.
Block.orphan() no longer adds orphaned transactions back to
unconfirmed pile as they are themselves deleted during
Transaction.orphan(). Maybe the answer is to NOT delete
them during Transaction.orphan() but to add them to
unconfirmed pile at that point? Very old transactions
leftover from major resync would simply expire, whereas
recently transactions leftover from minor resync could
still make it into a new block on synced chain fork.
Changes/tidying/improvements to block generator regarding
removing invalid transactions and dealing with transactions
pending group approval.
Approval threshold added to groups.
Mass refactoring of transaction-related classes to unify
constructors, particularly field ordering, to fall in line
with raw transaction layout.
e.g. constructors now reflect that raw transactions mostly
start with type, timestamp, txGroupId, publicKey, reference
e.g. JAXB afterUnmarshal methods added where needed and corresponding
nasty code in Transaction subclass constructors ripped out.
e.g. TransactionTransformer subclasses contain less duplicated code.
Fixed bug with repository save points thanks to swapping to Deque.
Some fixes to do with missing transaction types being passed to JAXB
TransactionData subclass constructors.
Ripped out obsolete toJSON in TransactionTransformers as this
is all nicely taken care of by Swagger/OpenAPI (thanks @Kc)
Some pom.xml changes to reduce maven-shade-plugin conflicting classes warnings.
Repository now supports SAVEPOINT and ROLLBACK TO SAVEPOINT.
HSQLDB concurrency/transaction model changed from LOCKS to MVCC to help with
transaction deadlocks/rollbacks.
More XXXs and TODOs added to Block.java for investigation/fix/improvements.
Also used new repository SAVEPOINT feature when validating transactions
instead of rolling back entire transaction. This fixes problem during
synchronization where the rollback would undo previously synchronized,
but not yet committed, blocks!
Transactions orphaned by Block.orphan ARE now added to unconfirmed pile,
unlike before.
Concurrent lock now prevents simultaneous block generation and synchronization,
including synchronization via multiple peers.
Lots of new networking code: peer lists, block signatures, blocks,
blockchain synchronization.
PEERS_V2 message now supports hostnames, IPv6 and port numbers.
Fixed bug with block serialization for transport over network.
DB shape change from v29 to add peer info.
New NetworkRepository to handle above.
Peer handshaking with v2 anti-DoS PoW code.
Handshaking refactored into a state-machine-like enum.
Some peer-related API calls added.
Peers exchange pings, heights, peers.
No actual peer sync yet.
Other changes:
Peer version info taken from Maven build properties/resource file.
AnnotationPostProcessor more resilient when fetching PathItems.
Per-repository session debugging flag that can be toggled at will.
HSQLDBRepository.delete() now returns int so callers can detect
whether anything was actually deleted.
Some renaming to settings.
API calls that return lists now take limit, offset and reverse params.
API calls that used to return data & optional list (e.g. blockWithTransactions)
now only return base data. The optional lists can be fetched via
a different API call.
Also: SLF4J now routes logging to log4j2 so start up output cleaned up.
Suppressed extraneous Jersey warning about Providers during start-up injection.
NB: we're still using HSQLDB svn r5836
Updated README.md
Added log4j2.properties file for logging!

Fixed Block so correct block hash and timestamps are generated,
especially when previous/next block versions differ.
Added extra call in BlockTransformer to aid this.
Fixed GenesisTransaction.isValid's incorrect amount test.
Fixed comments in TransferAssetTransaction and incorrect use of BlockChain.getVotingReleaseTimestamp()
instead of BlockChain.getAssetsReleaseTimestamp().
Added new TYPEs to HSQLDBDatabaseUpdates, and set LOB granularity to 1KB for AT use.
Added AT_address column to DeployATTransactions in HSQLDB.
Added ATs, ATStates and ATTransactions tables.
(You will need to discard existing database and rebuild).
Fixed incorrect byte array output in IssueAssetTransactionTransformer,
where Asset "references" were not processed correctly.
Added support for BigDecimal serialization to a byte-array size other than the standard 8.
