Release roundups are organized into a few categories spanning the breadth of the developer experience. From core protocol contributions all the way to the Hiro Platform in the cloud, let’s take a look at what we shipped in March and a preview of what we’ll be working on in April:

Release Roundup

Hiro Platform

  • In March, we shipped a new contract code view to offer you faster feedback loops. Now you can preview your contract code from the contract listing page, and this code preview can even verify your code and point out errors. Previously, this was a static list page, and you couldn’t see contract code without opening a code editor.
The new contract view in the Hiro Platform
  • With a new automation improvement, the Hiro Platform now streamlines the management of users' computing resources behind their projects. The platform now automatically halts the “compute” when not in use and seamlessly scales it back up when users log back in. This eliminates the need for users to initiate their workspace, reducing the likelihood of unintentional errors and enhancing the overall user experience.
  • Given that Chainhook is a critical path for many apps, we have enhanced its stability, providing users with a smoother, more reliable experience and reducing downtime significantly.
  • Clarinet 2.4.x and its devnet compatibility are both available now on the Hiro Platform, enabling you to test Nakamoto functionality and the PoX-4 contract in the platform.



  • We released v2.4.x of Clarinet, which upgrades devnet to improve epoch 2.5 handling, adds signers and signers-voting boot contracts. These features support Nakamoto and enable us to bring these capabilities to the Hiro Platform as well. Clarinet’s latest release also allows you to call a contract’s private functions in simnet.



  • We released v1.4.0 of Chainhook, which enables you to use a local rocksdb when using the <code-rich-text>chainhook predicates scan<code-rich-text> command, greatly speeding up scan time. This release also includes better error detection for http/rpc errors and a number of bug fixes.

API Services

Stacks Blockchain API

  • We released v7.9.0 of the Stacks Blockchain API, which creates two new address transaction endpoints. We also released the beta of the Nakamoto-compatible Stacks Blockchain API and will continue to make a number of improvements on this beta release as we gear up for mainnet instantiation in late April.


  • We continued to be one of the many contributors to the working group on the upcoming Nakamoto release. In March, we achieved the first major public step towards Nakamoto mainnet with the launch of testnet! Developers can now test their contracts against pox-4, and signers can begin onboarding.

Blockchain Explorers

Hiro Docs

  • We rolled out new overview pages in documentation for every Hiro product to better highlight what you can do with each of our tools and to make their most popular guides more easily discoverable. Check them out for yourself.

Looking Ahead to April

Here are our biggest priorities in April:

  • Supporting work towards Nakamoto mainnet: The biggest priority in the Stacks ecosystem is the Nakamoto upgrade, which comes to Stacks mainnet in late April. We are one of many contributors in the blockchain public working group progressing towards that goal. Learn more about the timeline to Nakamoto here
  • Preparing Hiro products for Nakamoto: We will also be finalizing Hiro products for Nakamoto-readiness on mainnet, so you won’t experience any disruption using our tools once the upgrade goes live.
  • Streamlined onboarding to the Hiro Platform: In April, we will roll out a redesigned onboarding flow in the Hiro Platform to more intuitively guide developers to get their job done.
  • Docs improvements: Keep an eye out for a new Hiro docs experience coming soon.

Beyond that we’ll of course have lots of work and upgrades to the suite of Hiro products, so keep an eye out for new updates.
