OpenST-protocol v0.9.2 March 27 2018

OpenST v0.9.2 improves usability to facilitate application by the OpenST-Platform and other services. Additionally, this release increases test coverage, with additional unit and integration tests, and adds continuous integration with Travis CI.

Detailed changelog:

• Introduce conversionRateDecimals to BrandedToken to treat conversion rate as a fixed point arithmetic number (openst-protocol #107)
• Expose list of registered tokens on OpenSTUtility (openst-protocol #89)
• Make token UUIDs iterable on the value chain (openst-protocol #103)
• Make token UUIDs iterable on the utility chain (openst-protocol #102)
• Incorporate a beneficiary into redeem and unstake (openst-protocol #101)
• Expose mints and redemptions on OpenSTUtility (openst-protocol #100)
• Expose stakes and unstakes on OpenSTValue (openst-protocol #99)
• Revise UtilityTokenAbstract to set certain invariants upon construction and to expose them (openst-protocol #97)
• Remove unneeded files (openst-protocol #93)
• Tests: configure Travis CI to run unit tests on master and develop branches for every commit, merge and pull request (openst-protocol #87, openst-protocol #105)
• Tests: denominate tokens consistently (openst-protocol #82)
• Tests: add unit tests for reversion functions (openst-protocol #74)
• Tests: migrate unit tests for Owned, OpsManaged, and SafeMath from SimpleTokenSale repo (openst-protocol #73)
• Tests: add integration tests for reversion functions (openst-protocol #65)

OpenST-protocol v0.9.1 December 19 2017

OpenST v0.9.1 is the first release deployed on Ethereum mainnet combined with the activation of Simple Token to power the OpenST platform. The OpenST platform allows Ethereum smart contracts to runs faster and cheaper while leveraging the security properties of Ethereum's Proof-of-Work. In this release we implement the first corner stone of the protocol: the ability to stake value on Ethereum mainnet and mint a new representation of that value on a utility chain, effectively increasing the computational throughput of Ethereum smart contracts by allowing parallel execution across chains.

OpenST smart contracts have been restructured to store value separately from the logic that implements the protocol. v0.9.1 is not yet protocol complete as the validators are whitelisted and not yet open with stake put forward on Ethereum mainnet. However, by splitting the protocol implementation into these two logically separate problems, we can already start working with member companies and developers to fine-tune the APIs and the developer experience to build mainstream applications on Ethereum.
