@gavofyork gavofyork released this 15 Oct 13:52
v1.3.8
e0778fc

Parity 1.3.8 is our EIP150 hard-fork compliant release.

Running this will enact a mild change of the protocol at block number 2,463,000 which should occur on Tuesday 18th October 2016 at approximately 12:20 London time (BST). This change alters the gas prices for a number of operations, mainly centring around i/o intensive Merkle trie lookups (BALANCE, EXTCODESIZE &c.) and state-trie polluters (SUICIDE, CREATE and CALL). These operations were heavily underpriced, an oversight which lead to the recent degradation of network service. The full details of the alteration are specified in EIP-150.

Additionally several issues have been fixed including:

  • a transaction queue limitation leading to dropped transactions;
  • a synchronisation issue leading to stalls when syncing;

And some small features including database performance improvements and additional logging.

Upgrading private chain specification files.

All the chain specification files now have EIP-150 rules enabled by default. To continue using the chain add the eip150Transition key under Engine/ethash/params and set it to a future transition block as shown in this example.

The key related to homestead transition has been renamed from frontierCompatibilityModeLimit to homesteadTransition.
