v0.15.0

Both this release (v0.15.0) and the previous release (v0.14.0) should work with polkadot v0.8.23.

• New /transaction/dry-run endpoint. See README.md and here for more info. (#236, #240)
• Slight optimizations to the /block endpoint. (#233)

v0.14.0

• Add node endpoints for version, transaction pool, and network information (#226)
• Add runtime endpoints for version and Wasm code (#228)
• Add staking payouts endpoint for claimed and unclaimed staking rewards of a stash address (#217)

v0.13.0

This release is approved for Polkadot version 22 (the version of the upcoming runtime upgrade).

Api noteworthy

• Enhanced transaction error messages. These are non-breaking changes as they only add fields to the response. (#202)
• noMeta query param for tx/artifacts that allows the user to specify that they do not need the metadata. This is useful if endpoint response time is a concern and the user already has the metadata. With no query param input the endpoint signature remains unchanged. (#222)

Other

• Increased test coverage of services.
• Internal updates to the response normalization engine. (#154)
• Updated sample docker setup. (#191)
• Bump dependencies. (#219, #211, #206)
• Updated openapi proposal. (#209)

v0.12.0

• Breaking change to /block response by removing newArgs field and updating the args field in extrinsics (#186). We recommend phasing out the use of newArgs and upgrading to this version as soon as possible in order to be ready for subsequent version bumps that may be mandatory.
• Internal refactor of services and additional unit tests (#171, #181, #184)

v0.11.3

• API bump for Polkadot runtime 15
• More unit testing

v0.11.2

Urgent Release for New Polling Pallet

• Bump API to include new types in Polkadot's Polling Pallet. (#169)
• Improve test coverage.
• More useful console output regarding to which network sidecar is connected. (#158)

v0.11.1

• New 400 error to warn when a specified block number is too high (#131)
• Upgrade all dependencies (#90)
• Changes in ApiHandler and sanitizeNumbers to compensate for @polkadot-js api updates (#90)
• Refactor error handling by moving it all out to middleware (#143)
• Add configuration validation to warn when a env var is not valid (#149)

v0.11.0

• Improved configuration management using confmgr. ENV var specs are now in specs.yml and there is improved compatibility with .env files. N.B. all configurable ENV var names have changed; they now include longer prefixes. You can find more details in the updated README.md
• Validations for ensuring address URI params are in a substrate compatible SS58 format. Multiple new 400 errors are added in the validation process including, but not limited to, 'Invalid decoded address length' and 'Invalid decoded address checksum'.
• Bump @polkadot-js deps to v1.23.0-beta.2.

v0.10.0

• New /staking-info endpoint to get information on the progress of the staking system components.
• Bump @polkadot-js deps.

v0.9.2

Bump @polkadot-js scoped dependencies to 1.20.0-beta.3 (#108).
