Release 2.0.4e

This is an experimental release for testing only. Source code is not provided.

Change log:

This Ardor platform release introduces several important new features.
It is for testnet only, and involves a reset of the existing testnet and
starting from a new Genesis block.

Major new features:

- - Asset Control.

Similar to Account Control which once set requires all transactions of an
account to be subject to approval (i.e. to use phasing), the new Asset Control
feature allows imposing such restriction to all transactions involving a given
asset - such as placing bid and ask orders, transfers, share deletions, and
dividend payments that use the asset as a dividend.
This feature enables for example a private company to issue its shares on the
Ardor blockchain, yet to impose control over who can purchase or sell them, for
example requiring asset transactions to be approved by its board of directors,
or a shareholder voting.
It also allows asset issuers to be KYC compliant, by only allowing verified
accounts to transact with their assets.

- - Composite Phasing

The Composite Phasing ("Smart Phasing") is a very powerful new feature that
allows approval models for conditional transactions to be defined in terms of a
Boolean combination of other approval models, i.e. allows joining the current
primitive approval models such as by whitelist, by asset balance, by hash, etc,
using the AND, OR, and NOT operators.
This allows the new Asset Control feature to be used in combination with the
Account Control feature when required, the transaction execution being made
conditional on satisfying both the Asset Control and Account Control settings.
It also allows for example combining the existing by hash or by transaction
approval models with by whitelist, by balance, etc, approvals, which enables
doing atomic coupling of transactions (including cross-blockchain) even for
multisignature accounts (i.e. subject to Account Control), or with assets
subject to Asset Control.
The NOT operator allows for dead-man-switch type conditions, where a
transaction is executed only if some condition (e.g. revealing a secret) is not
satisfied.

- - By-Property phasing

The new by-property approval model allows the transaction execution to be made
conditional on the sender account or the recipient account having a specific
account property set. If this property is set, the transaction will be executed
immediately, else, a second check whether the property is set is performed at
the finish height defined. This allows for example enforcing KYC by asset
issuers, who can define in their Asset Control settings that only KYC-verified
accounts, labelled with a predefined account property by a trusted authority
(or the asset issuer itself), to perform transactions with their assets.

- - Asset share increase

A new transaction type has been added, allowing the asset issuer to increase
the total number of asset shares in existence. The new shares are allocated to
the asset issuer account, but can be then distributed to shareholders using
a separate dividend payment transaction. This allows corporate actions such as
capital increases or stock splits to be performed.
