Parity 1.9.0-beta "Velocity"

We are happy to announce our newest Parity 1.9 release. Among others, it enables the following features:

• It integrates the fully reworked Parity Wallet and DApps browser (a.k.a. "UI 2.0", #6819).
• It enables devp2p snappy compression (#6683).
• AuRa Proof-of-Authority chains now disable uncles by default (#7006). Existing PoA chains can go through a "maximum uncle count transition" to achieve more stability (#7196).
• Added Expanse's Byzantium hard-fork (#7463).
• Added support for Ellaism chain (#7222).

Further, users upgrading from 1.8 should acknowledge the following changes:

• Fixed DELEGATECALL's from/to field (#7568).
• Set zero nonce and gas price for calls by default (#6954).
• Create pending blocks with all transactions from the queue (#6942).
• Remove RPC parameter leniency now that Mist formats correctly (#6651). Parity stops accepting decimal-formatted block numbers and stops parsing the empty string as empty bytes.
• Public nodes do not support the user interface anymore. If you are running a public node, please stay on the 1.8 branch of the stable releases.

Additional noteworthy changes:

• ethstore and ethkey have been significantly improved (#6961):
  • ethstore now supports brute forcing pre-sale wallets given a password list for recovery.
  • ethkey now supports multi-threaded generation of prefix-matching addresses.
  • ethkey now supports prefix-matching brain wallets.
  • ethkey now supports brain-wallets recovery-phrases lookup. This helps to find a correct phrase if you know the address you want to get yet you made a typo backing the phrase up, or forgot a word.
