1.11.0 Petersburg

Introduces Constantinople hard fork version without EIP-1283 which is internally called Petersburg. Block numbers:

• Mainnet 7,280,000
• Ropsten 4,939,394

1.10.1 Constantinople postponed

Cancels Constantinople hard fork on Mainnet at block #7_080_000.
Bug was found in EIP-1283 - reentrance vulnerability, so hardfork is delayed until the issue is solved.

1.10.0 Constantinople on Mainnet

Enables Constantinople hard fork on Mainnet at block #7_080_000.

A couple of fixes is, also, coming with this release:

• Fix ABI code for multidimensional arrays #1239
• Compiling with solc 0.5.0 broken #1244, thanks to @tbocek

1.9.1 Post-constantinople fixes

List of fixes:

• Constantinople is now starts at correct block on Ropsten #1214
• Headers validation is improved #1222
• EXTCODEHASH corner case fixed, could result into consensus break #1228

1.8.2 Hotfix Release

Fixes consensus break happened on the main net, block 6,108,275

1.8.1 Hotfix Release

Fixing Memory referencing with 0 data size in VM #1109
Prevent early switch to SyncState.COMPLETE #1105

1.8.0 Release

This release scope represents an ongoing work in performance improvement area and aims finishing of DB transition made by EthereumJ in the previous release. Though we've switched to RocksDB formally on v1.7.0, that version and consequent updates were very slow in terms of processing blocks during regular synchronization. Moving to the other DB engine is a big task, and we were not able to do it in one step. Now we got 5-10x block processing time improvement comparing to 1.7.x, faster regular sync than we had with LevelDB and speed which puts us to the next target: matching top clients performance. We are still slower but the difference is not in range of an order.

Along with database we were working on network improvements, which affects client speed too. Targeting memory usage, peer abuse and network attacks we've made changes which refines both regular and fast sync. See full change set below.

Features

• Convenient sync management for private networks #1094, #1050
• New gas price tracker #1056
• Ethhash events listener for miners #1084, #1095
• Local run configuration for Github tests #1087

Improvements

• Memory limit on outgoing eth messages #1057
• Reduced sync queue memory footprint #1062,
• Fast Sync memory improvements #1074, 02de75d
• Boost RocksDB.get() which increases processing speed from 5 to 10 times depending on the env #1061
• Resistance to attacks with wrong RLP length #1073
• Fast Sync peer rotation improvement #1074
• Basic protection from eclipse attacks #1082
• Limited outgoing transaction size a3535b0

Fixes

• Incorrect blocks total difficulty and ETH header responses in sync.fast.skipHistory mode #1060
• Race condition in BlockchaiNImpl.updateBlockTotDifficulties() 99e22a5
• Sync fallback into infinite loop in private networks e0730e2

1.7.3 Hotfix Release
