This patch serves as a hotfix for a few issues discovered in the 3.7.3.0 leisure update. This is a leisure update, and is not mandatory for users. If you have issues installing the MSI, please try uninstalling the previous wallet installation and reinstalling fresh from this MSI.

Download the update from GitHub [here](https://github.com/gridcoin/Gridcoin-Research/releases/tag/3.7.4.0).

You can also download the Windows MSI [here](https://download.gridcoin.us/download/downloadstake/GridcoinResearch.msi). Remember to backup your wallet.dat and config file before updating!

Note that the in-wallet upgrader is still not working at this time.  *Please do not upgrade from inside the wallet!*

Below is the changelog for this release:


Fixed

    Fix RPC resource leak regression. This also reduces RPC overhead,
    making calls ~25-35% faster, #848 (@denravonska).
    Fix incorrect return code when forking, #832 (@denravonska).
\
Removed

    Remove upgrader option until rewritten, #836 (@Foggyx420).

While this patch is only a leisure update, please remember to upgrade your wallets to at least 3.7.0.0 before the hard fork at block 1,144,000!  If you do not upgrade your wallet to a 3.7 version by that block you will be left behind on a fork!
