v3.0.0-beta3

Highlights

Yaci Store 3.0.0-beta3 is a Protocol Version 11 hard fork-ready beta release with major progress on Blockfrost-compatible APIs, governance correctness, epoch nonce calculation, and operational tooling.

Release Line Update

The previous 2.1.0-pre* release line has been renamed to the 3.0.0-beta* release line.

Going forward, Yaci Store will use two active release lines:

• 2.0.x: stable releases
• 3.0.0-beta*: beta releases for the next major version

This change is intended to reduce confusion around the earlier 2.1.0-pre* naming. The 3.0.0-beta* line continues the work that was previously published under 2.1.0-pre*.

Blockfrost-Compatible API Support

This release adds or improves Blockfrost-compatible API coverage across multiple modules.

Supported or expanded modules include:

• Epoch APIs
• Address APIs
• Asset APIs
• Block APIs
• Transaction APIs
• Account APIs
• Metadata APIs
• Scripts APIs
• Transaction submit and utility endpoints

Blockfrost sub-modules are now enabled by default when the parent Blockfrost module is enabled.
