# Changelog

Published releases and migration notes for @masterpeach/arc-aggregator-sdk.

### Integration guide update — 2026-10-12

Direct examples now call `swap()` once for quote and transaction, then confirm and submit that same result. Delegated examples retain prepare → payer signature → build. These documentation changes use the existing 1.0.0 API; they do not announce a new ARC SDK release.

### 1.0.0 — 2026-09-15

First stable release of `@masterpeach/arc-aggregator-sdk`.

* **Swap workflows:** Independent route previews, Direct Allowance swaps and delegated Permit2 Witness execution.
* **Pool identifiers:** Provider-native `bytes32` pool IDs for Uniswap V4.
* **Validity:** Swaps default to 120 seconds. Validation tolerates a client clock up to 60 seconds behind without extending signed deadlines.
* **Compatibility:** Existing 0.3.x integration methods are unchanged.

### 0.3.0 — 2026-09-07

* Restores `ApiClient.findRoutes` and `ArcClient.findRoutes` for independent route previews.
* **Breaking from 0.2.0:** replace `ArcClient.prepareDirectSwap(params)` with `ArcClient.swap(params)`. Parameters and `PreparedDirectSwap` remain the same; the application submits `tx` separately.
* Call `swap()` once for the quote and transaction, then confirm and submit that result.

### 0.2.0 — 2026-09-07

* Direct Allowance and delegated Permit2 Witness swaps through the Execution Router API.
* Delegated execution uses `prepareDelegatedSwap → signPayerAuthorization → buildDelegatedSwap`. Prepare does not require `unsigned_tx`; build returns the complete transaction.
* Custom fee arithmetic, fee receivers, protocol splits, requested slippage, and final execution calldata are validated. Authorization snapshots remain stable while awaiting wallet calls.
* Server-selected providers support Launchpad bonding curves before graduation and Uniswap V4 pools after graduation and pool creation.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.peach.ag/documentation/arc/aggregator/changelog.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
