# Protocol changelog

> A dated record of protocol releases, capability launches, and parameter changes.

Every protocol release, capability launch, and change to network parameters is recorded here with the date it took effect.

This is the record of what shipped. For what is running and what is coming, see [Milestones](/protocol/roadmap/milestones) and [What's next](/protocol/roadmap/whats-next).

<Update label="Private testnet" description="Live">
  **The private testnet is running the full protocol stack.**

  Consensus, the execution kernel, the order book, the clearinghouse, the oracle, vaults, the bridge, and the data surfaces are all live and exercised continuously against sustained load.

  This is a closed network. It exists to prove the invariants the [public testnet](/protocol/roadmap/milestones) gates on — replay determinism, no out-of-bounds actions reaching the book, and simulation fidelity against actual fills — before access opens on **20 September 2026**.

  See [Milestones](/protocol/roadmap/milestones) for the full list of delivered capabilities.

## What gets recorded here

Once the public testnet opens, every entry below will be one of:

| Type                  | Example                                                                      |
| --------------------- | ---------------------------------------------------------------------------- |
| **Protocol release**  | A new version of the node software, and what changed in execution            |
| **Capability launch** | A capability moving from [What's next](/protocol/roadmap/whats-next) to live |
| **Parameter change**  | Risk parameters, leverage tiers, funding caps, or fee schedules              |
| **Market listing**    | A market opening or being retired                                            |
| **Breaking change**   | Anything requiring integrators to act, with the notice period given          |

Entries are dated by when the change took effect on the network, not when it was announced. Changes that affect open positions or integrations carry a notice period, announced ahead of the effective date under [Rule changes](/programs/rule-changes).

<Note>
  Protocol behavior is versioned on-chain, and changes take effect at a specific block height that must be in the future when it is recorded. Whether a given rule was active at some past version can therefore never be rewritten after the fact — replaying an old block always applies the rules that were active then.
