Let’s take a look at what we shipped in August across all of Hiro’s devtools, and share some of our priorities for September.
Release Roundup
Clarinet
- Custom PoX contracts in simnet: Previously, Clarinet bundled a fixed set of boot contracts. Now, Stacks Core developers can load custom code for existing boot contracts or introduce entirely new ones in simnet. This streamlines Core development and makes testing critical upgrades far more flexible.
- Latest Explorer in devnet: A few months ago we revealed the latest and greatest Stacks Explorer that came with a complete redesign. Experience the same newness when navigating the Explorer version in devnet for your local testing and iteration on your contracts.
Stacks Blockchain API
- Smaller payloads, more reliable queries: In v8.12.0 and above, you can slim down transaction responses with the new exclude_function_args parameter. We also fixed an edge-case bug with PoX cycle pagination and ensured coinbase transactions are fully captured. Together, these updates make the API faster, lighter, and more accurate for production apps.
- Store And Push Integration: Recent upgrades to the Stacks Blockchain API have boosted both availability and reliability. The latest version introduces Store and Push (SNP) — a high-performance internal service that streams Stacks node events exclusively through Hiro’s APIs. With SNP, the Hiro-hosted API is now more fault-tolerant, automatically recovers data, and runs leaner with fewer moving parts.
Documentation
- Hola desarrolladores de Stacks: Our documentation is now available in Spanish, empowering developers across Spanish speaking countries and around the globe to learn faster and build more efficiently in their native language.
Platform
- More accurate real-time API usage data: A new unified data pipeline now powers granular insights—down to services, endpoints, and response codes. This data is surfaced in the Platform UI, giving builders instant visibility into their app’s activity.
Looking Ahead to September
Here are some of the big things we’re working on in September:
- Alpha launch of Chainhook 2.0: An Alpha release of the upcoming revamped Chainhooks will be rolled out to a select group of teams in the ecosystem for comprehensive testing. The new Chainhooks will focus on high performance and stability for realtime filtered event delivery.
- ReOwn integration with Stacks Connect: ReOwn (formerly WalletConnect) will be natively integrated into Stacks Connect, making it easier than ever for web3 apps and wallets to onboard Stacks without building custom configurations. Existing Stacks apps and wallets can also take advantage of this integration to seamlessly support multi-chain operations.
As always, we will be shipping new features and upgrades outside of what’s listed here. Keep an eye out for new updates.
