Dear BitShares User and Business Partners,
the BitShares Blockchain Foundation is pleased to let everyone know about the upcoming protocol upgrade for the main BitShares Blockchain.
The new release comes with three highlights for the community:
The core team has changed the versioning of the Core software to
Protocol.Feature.Hotfix release format beginning from
Hashed Timelock Contracts (HTLC) The building blocks for Atomic Cross Chain Swaps (ACCS) and other solutions based on the HTLC concept.
Sharing of Market Fees Asset issuers and gateways can chose to share market fees with with referrals with an adjustable percentage.
We encourage everyone to go through the release notes .
This is a protocol upgrade release. All nodes must upgrade before

This is how you can upgrade from source:
git fetch origin git checkout 3.0.0 git submodule sync --recursive git submodule update --init --recursive # it follows the usual compile instructions with cmake and make
A new docker container is currently built by Docker Hub and will be available shortly via
docker pull bitshares/bitshares-core:3.0.0
The detailed lists about bug and security fixes can be found in the Release Notes 
We would like to remind everyone of the mailing lists  operated by the BitShares Blockchain Foundation where business operators and users can engage discussions and get the most recent updates, directly. An distinct mailing list for critical operation updates exists, too.
The new release modifies the blockchain protocol and due to this is a consensus-changing modification. While the usual terminology for this kind of upgrade in other blockchains is hard-fork, we would like to emphasis a new term for Graphene-based blockchains: protocol upgrade. The reasons we distinguish our upgrades from a hard-forks, is that our consensus mechanism - delegated proof of stake (DPOS) - does not allow for the blockchain to split into two (or even more) independent blockchains. BitShares comes with an inherent replay protection and together with BTS holder-approved block producers cannot result in a splitting of the blockchain.
The BitShares Blockchain Foundation would like to acknowledge the efforts taken by the entire core team and is looking forward to more excellent releases.
