ardor-client-3.0.1e, released 2022-02-17:

This is a mandatory upgrade for the experimental 3.0 Ardor testnet only. It
should not be used with the stable 2.3 Ardor mainnet or testnet.

Multiple bugfixes. Base functionality is now up-to-date with 2.3.4.

ardor-client-3.0.0e, released 2020-12-28:

This is the first release of the Ardor pruning and snapshotting feature. It is
experimental and for testnet use only. A new testnet has been created, starting
from a snapshot of the current testnet as of Dec 8, 2020. Users having testnet
balances as of the snapshot height, block 6248612, should have the same initial
balances on this new testnet. The 3.0.0e release cannot be used with the
current 2.3.3 mainnet or testnet however.

To enable pruning of child chain transactions, the nxt.pruneChildChains=true
property must be set (default is false). If this is enabled, child chain
transactions are not processed during blockchain download and are pruned from
storage during normal operation. During download, only the parent Ardor chain
is processed; when the download is finished, the blockchain state (consisting
of child chain balances, asset holdings, aliases, etc - everything an account
owns) is loaded from a state snapshot, downloaded from the network and
confirmed by at least 720 blocks or as set in nxt.stateSnapshotConfirmations.

The peer networking port for the 3.0 testnet is 16874 and the API port is
16876 (SSL port 16877, if enabled). The different ports allow this version to
be run in parallel with 2.3.3 mainnet or testnet instances.

Block times have been set to 30 s for this testnet.

Users familiar with running Ardor nodes are invited to join the 3.0 testnet by
installing this release and report any issues in our support forum,

Apart from the major new pruning and snapshotting feature, there should be no
difference in functionality compared to 2.3.4.
