[ᚬmaster] Rc/v0.15.0

[doitian]

• Target Release: v0.15.0 (rylai v4)
• Release Date: Jun 29, 2019

The default secp256k1 has changed. Now its code hash is

0x94334bdda40b69bae067d84937aa6bbccf8acd0df6626d4b9ac70d4612a11933

Highlights

• feat: proposer reward #922: Feat: proposer reward (@zhangsoledad)

  This is a breaking change: b:consensus

  1. earliest transaction proposer get 40% of the transaction fee as a reward.
  2. block reward finalized after proposal window close.
  3. enforce one-input one-output one-witness on cellbase.

• Replace system cell #1054: Replace system cell (@driftluo, @jjyr)

  See feat: use recoverable signature to reduce tx size by jjyr · Pull Request #15 · nervosnetwork/ckb-system-scripts

  BREAKING CHANGE: It changes the default secp256k1 script, which now uses recoverable signature.

Features

• feat: initial windows support #937: Initial windows support (@xxuejie)

• feat: add a function to select all tx-hashes from storage for a block #931: Add a function to select all tx-hashes from storage for a block (@yangby-cryptape)

• feat: network alert #910: Implement the alert system in CKB for urgent situation (@jjyr)

  This is a breaking change: b:p2p, b:rpc

• feat: explicitly specify bundled or file system #939: Explicitly specify bundled or file system (@doitian)

• feat: Add load_code syscall #972: Add load_code syscall (@xxuejie)

• feat: Upgrade p2p #977: Upgrade p2p (@driftluo)

  • upgrade p2p dependence
  • support upnp optional

• feat: use new identify protocol #978: Use new identify protocol (@driftluo)

  The current identify protocol does not play a role in identifying the capabilities of both parties, and the message structure is not reasonable.

  So, I rewrote it and added the capability ID and network ID.
