Chia-Network/chia-blockchain 1.7.0 on GitHub

1.7.0 is now available for download. This release brings a new feature that allows Offer makers to send notifications to NFT owners for an available offer to better promote discovery for NFT owners. Along with other UX improvements, there are also some necessary security fixes, for which we strongly recommend everyone to update their client, especially those running full nodes.

With the release of 1.7.0, a soft fork will occur at block 3630000, roughly 90 days from today. (Note that this fork has nothing to do with the proposal to reduce the plot filter, as outlined in this proposed CHIP). See the blog for details.

For End Users:
Offers update:

⚠️ Offers that are generated with this version 1.7.0 cannot be accepted with older versions of Chia
Chia 1.7.0 can accept any offer, including ones created with older versions.

NFT updates:

NFT search bar - whether you are in the gallery view trying to find a specific NFT, or you are planning to sell an NFT you own, NFT search allows you to search based on the NFT title, NFT ID, or collection name to help narrow down your choices.
Bulk actions can be performed on several NFTs at once. You can multi-select NFTs to transfer to another wallet, transfer to a profile, show or hide the NFTs, send to the burn address, create an offer, or refresh the NFT data.

General updates:

Dynamic fee estimator for those running the full node. This will provide a recommended fee based on the amount of activity in the mempool. You are still able to choose 0 as a fee if you are comfortable waiting. Those running the light wallet will still get the default fee values.
Import wallets that use 12 word mnemonics. You can only import, but this allows you to use the Chia reference wallet with other wallets you have created.

For Developers:

RPC and CLI commands to enable combining coins and splitting coins. This will allow you to break up large coins more easily or combine smaller coins into larger coins.
⚠️ Python 3.7 support is deprecated and will be removed in a future version

Known Issues:

Pressing CTRL-C while running CLI commands will throw a traceback error
Errors may show up in the debug.log when fetching incoming offer notifications: WARNING Error while handling message: Traceback (most recent call last): This does not affect the ability to receive or view incoming offers and can be safely ignored.
Large log entries are included in the debug.log files. The errors will start with: wallet chia.wallet.wallet : WARNING Record: . These errors can be safely ignored.
