Change log:

This is a stable release, introducing multiple enhancements and bugfixes. It
is a recommended upgrade for production use.

On testnet, upgrade before block 3250000 (expected Nov 7, 2019) is mandatory
due to the activation of the following new features that require a hard fork:

Allow sending zero fee child chain transactions even from accounts not yet
registered on the blockchain.

Allow setting up account control with zero max fees. This completely removes
the risk that an attacker who obtains the passphrase of an account placed
under account control may slowly waste its funds on fees, however the
transactions fees for such an account will need to be sponsored, i.e. its
transactions must be bundled by some bundler for free.

The above features will be available on testnet after block 3250000, and will
also become enabled on mainnet at the next scheduled hard fork.

The node processes management add-ons:

SaveForgingEncrypted, StartForgingEncrypted,
SaveFundingMonitorsEncrypted, StartFundingMonitorsEncrypted,
SaveBundlingEncrypted, StartBundlingEncrypted,
SaveStandbyShufflingEncrypted, StartStandbyShufflingEncrypted,

have been replaced respectively with:

ForgingEncryptedConfig,
FundingMonitorsEncryptedConfig,
BundlingEncryptedConfig,
StandbyShufflingEncryptedConfig.

If you have enabled any of those in the nxt.properties file, the nxt.addOns
property must be updated with the new add-on classname.

For add-ons in the nxt.addons package, such as the process management add-ons,
specifying the full Java package name is now optional, i.e. if only the class
name is specified in the nxt.addOns property, it is assumed to be in the
nxt.addons package.

Each of the new add-ons exports two http APIs, to allow saving the encrypted
configuration and starting the corresponding process.

The EncryptedConfig add-ons now by default use files under the conf/processes
directory to save the encrypted processes configuration, overwriting existing
files if needed. An alternative location can be specified using the
nxt.addons.EncryptedConfig.path property. When using the API, the config file
can also be saved under any other path, as long as it does not overwrite an
existing file.

Client-side encryption is also supported by the SaveEncrypted add-on APIs. If
the config data is already encrypted, the dataAlreadyEncrypted=true request
parameter must be set, and there is no need to submit the encryptionPassword.

All of the above forging, bundling, funding monitors, and standby shuffling
process management add-ons are now fully supported by the wallet UI.
A "Processes" page has been added, accessible under the cogwheel menu, from
which the configuration of currently running forgers, bundlers, funding
monitors or standby shufflers can be saved to an encrypted configuration file,
and restored again after a node restart by supplying the encryption password.
The corresponding add-ons must first be enabled in the nxt.properties file in
order for the option to save/start them to appear in the Processes page.

A tutorial and documentation is available at:
https://ardordocs.jelurida.com/Node_Processes_Configuration

The wallet UI now allows attaching an unencrypted message also to transactions
that do not have a recipient.

Multiple UX improvements to reduce or automate the switching between chains
that is sometimes needed when the user tries to access a feature or submit a
transaction not supported on the current chain.

The Standby Shufflers UI has been improved to show the numbers of shuffling
recipient accounts remaining and currently in use.

The Funding Monitors UI, available under the cogwheel menu / Monitors, now
allows starting a funding monitor for assets or monetary system currencies,
not only for child chain coins. Funding monitors for such holdings must be run
on a chain that allows asset transfer or currency transfer transactions, i.e.
not on the parent Ardor chain.

The startFundingMonitor and getFundingMonitor APIs now support an optional
includeHoldingInfo parameter, to request the asset or currency info to be
included in the response json.

Setting up https on a public node running Ardor has been made simple, without
the need for a reverse proxy. The new pem.to.pkcs12.keystore.certbot.hook.sh
script can be used to convert an SSL certificate issued by Let's Encrypt to
a keystore file that the Ardor node can use. The run.sh script now supports
authbind, if started with the --authbind modified, to allow the Ardor software
to listen on port 443 without having to run it as root. A detailed tutorial
putting everything together is available at:
https://ardordocs.jelurida.com/Configuring_HTTPs_on_a_standalone_Ardor_installation

A new managePeersNetworking API has been added, to allow disabling or
enabling the node peer networking at runtime. It takes a single "operation"
parameter, with possible values: "enable", "disable", and "query", and
requires the adminPassword when run on a public node.

A new property has been added, nxt.deleteProcessedVotes=true, to optionally
disable the deletion of votes records when trimming the votes table. Note
that even if votes are not deleted, re-calculation of poll results may require
data that are no longer available (such as account or asset balances at the
time of poll finish), unless a blockchain rescan is done, this is why the
default is still to delete old votes records.

The compact.sh script has been improved to better reduce the database size.
A new property has been added, nxt.disableCompactOnShutdown=false to allow
disabling database compact on shutdown, for faster restarts during development.

The export/import functionality for contacts and approval models, as used in
the browser based wallet UI, is now available and compatible with the JavaFX
based desktop wallet too.

The Contract Runner doesn't require anymore an initial configuration on
nxt.properties or an external JSON file. Instead, it can be bootstrapped
from the new Processes page or from an uploaded configuration file.
The recommended configuration procedure is now the Processes page as it
provides a persistent configuration using encryption instead of plain text
files. It also helps with the initial configuration. When you open the
Save modal window for Contract Runner under the Processes page you are presented
with a basic minimum configuration like this:

{
  "accountRS": "ARDOR-XXXX-XXXX-XXXX-XXXXX",
  "autoFeeRate": true,
  "validator": false,
  "params": {}
}

The accountRS will match the currently logged in account, but you can change it.
You only need to enter the passphrase for the account and then the encryption
password. The UI will take care of adding the passphrase to the configuration
file before encrypting it locally and sending to the node for persistent
storage. In order to start the contract runner use the Start button under the
Processes page. After restarting the node you only need to start it again.

The Contract Runner can now calculate the best fee when sending transactions
instead of relying on a fixed fee ratio. There is a new 'autoFeeRate' boolean
property to enable this new feature. If set to true (default: false), the
contract runner will calculate the best fee available based on the current
bundlers. This should be equivalent to the "Calculate Fee" button on the wallet.
When autoFeeRate is set to false, or the best fee cannot be obtained, the
contract runner will revert to using the usual "feeRateNQTPerFXT.<Chain Name>"
properties.

Two new optional properties for the contract runner allow filtering out
bundlers used to retrieve the best available fee when autoFeeRate is activated.

Bundlers with an effective balance below the property minBundlerBalanceFXT
are not considered for the best fee calculation. The default for this property
is to use the same value as the global property nxt.minBundlerBalanceFXT.

Also, bundlers with a fee limit currently below the property
minBundlerFeeLimitFQT are also not considered for the best fee calculation.
Again, the default for this property is to use the same value as the equivalent
global property.

Added ChangeHero as an integrated exchange in the wallet.

Node.js module fixes and improvements.

Various UI improvements and bugfixes. Updated the icons to Font Awesome Pro
5.11.2 (commercial version). Android related UI fixes.

Updated H2 to version 1.4.200. If using a custom nxt.dbParams or nxt.dbUrl
properties, remove any MVCC settings from them, MVCC is now the default and
not configurable.

Updated Jetty to version 9.4.22.
