Hellar Core v1.2.0.5

Hellar Core version 1.2.0.5

We are happy to announce the release of 1.2.0.5
Release is now available from:

https://github.com/hellarcore/Wallets

This is a new hotfix release. All nodes should upgrade. Masternodes must use the Gen-wallet to work on air, if it was started on a ordinary
version of wallet, must stay on it!

Please report bugs using the issue tracker at github:

Upgrading and downgrading
How to Upgrade
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Hellar-Qt (on Mac) or hellard/hellar-qt (on Linux).

Downgrade warning
Downgrade to a version < v1.0.1
Downgrading to a version older than v1.0.2 is not supported due to changes in the indexes database folder. You don't need to use an older version.

Downgrade of masternodes to < v1.0.2
Starting with the 1.2.0.5 release, masternodes verify the protocol version of other masternodes. This results in PoSe punishment/banning for outdated masternodes, so downgrading even prior to the activation of changes is not recommended.

Notable changes
This release fixes an issue where outdated qfcommit messages replayed to the network were validated and propagated to other nodes rather than dropped. This patch updates the behavior so that old qfcommits will no longer be relayed.

Added missing mempool locks
Bumped version to 1.2.0.5
Flush chainstate (and prodb) cache whenever prodb mem usage is getting too high
Updated leveldb subtree
Added new sporks nodes, in MainNet & TestNet
Rised up speed bumping for spork nodes
Rised double transaction speed protacol
Masternode cache rised accordingly to sporks speed up
Fixed trailing whitespaces in release notes
