# Blockchain Release: Network Improvements

The core developers have tagged a new 2021.06.18.0 Hotspot firmware release which contains network improvements related to NAT and bug fixes related to staking for Validators. This is a required release for Hotspot owners. As some of the community members have noticed that the blockchain has not generated a new snapshot since the last GA, we believe that the improvements to networking and an increment to snapshot memory generation limit will fix snapshot generation. The core developers plan to do another minor release with a snapshot update once it gets generated by the blockchain.

Below are the related PRs:

• #### Network improvements​

The core developers have squashed a few NAT related bugs in erlang-libp2p, we believe these fixes should significantly improve Hotspot sync.

• #### Blockchain Bug fixes​

A few blockchain-core bug fixes are also packed in this release specifically around snapshot generation and staking bugs observed on the Testnet.

### Plan​

We have been beta testing 2021.06.18.0 since June 18th, 2021 10:30 AM PT. Current ETA for GA is 2:00 PM PT, June 18th, 2021.
