Introducing Overledger 2.1.1

DOWNLOAD THE UPDATE

The latest release of Overledger provides support for the Ethereum London hard fork.

EIP-1559 is expected to lead to faster transaction processing times and lower fees, which  Overledger 2.1.1 users will benefit from. And because the latest version of Overledger has transparent backward compatibility, developers can carry on using Ethereum networks that have not implemented EIP-1559.  

The underlying technology stack and framework versions of Overledger have been upgraded with this release and improvements have been made to APIs to:

  • Enhance Open API 3.0 compliance
  • Clarify array definitions and validations
  • Clearly define string parameters and validations
  • Ensure ‘schemes’ are clearly defined as HTTPS only  

With Overledger 2.1.1, API documentation for requests, responses and examples are generated programmatically and made accessible on  https://docs.overledger.io
Lastly, Quant has implemented the backend functionality that will allow developers to pay for license fees using Metamask. The outstanding UI changes and integrations will be part of a future release.

2021 Achievements

50% Quant team has grown by over 50% and will continue to do so 

OVL1.0 to 2.0 Release schedule accelerated, moved to much more frequent automated updates
– Previously, last major update was seven months, then in early 2021 moved to three months (Jan and March)
and then to monthly (April and May). We’re now moving to fortnightly releases. 

2.5X Overledger is now 2.5x bigger (April)  

2.0 Re-engineered the entire 2.0 architecture

Open API 3.0 for easy integration into developer workflows

OAuth 2.0 for single sign on for enterprise customers    

Cloud Native Scalable and resilient already, now deployable automatically 

New OVN API
