Stellar Development Foundation launched redesigned developer documentation at developers.stellar.org, featuring improved navigation, updated content, and new learning paths for asset issuance, anchor services, and app development.
The Stellar Development Foundation released a daily-updated analytics dataset on Google BigQuery, enabling 10-100x faster queries across the entire history of Stellar network transactions. The dataset includes accounts, ledgers, operations, trades, and other ledger state information, with free trial access available through Google Cloud.
The Stellar Development Foundation's web products team is seeking community feedback on a redesigned version of the Stellar developer documentation and API reference. The new docs feature improved navigation, modular learning paths, and updated content while maintaining existing functionality.
Horizon 1.0, Stellar's open-source API, launches with a new ingestion engine that makes queries faster, more consistent, and less dependent on Stellar-Core. The major release includes breaking changes and new endpoints for asset trustlines, multi-sig account discovery, and network-wide offer filtering.
Stellar Development Foundation released Horizon v0.20.1 with a new ingestion system that addresses architectural issues by building a full copy of ledger state from history archives instead of relying on Stellar-Core's database. The update enables new features like "Accounts for Signers" and significantly improves path-finding performance by up to 10x.
The Stellar Development Foundation announced a new ticker API providing real-time market data about assets, markets, and issuers on the Stellar Network.
