# 1.x

Plain-language release notes for the early `1.x` line — what changed in each mainline release, in plain terms. This complements the auto-generated [`CHANGELOG.md`](https://github.com/zama-ai/sdk/blob/main/CHANGELOG.md), which lists every commit.

## 1.1.0

*Released 2026-03-13.*

The first feature release after `1.0` — a cleartext development mode, session-aware signing, better React/wagmi integration, and a round of integrator-friction and security fixes. No breaking changes.

* **Cleartext development mode.** A new cleartext FHEVM mode runs the SDK unencrypted for local development and testing; its configuration was reworked into a flat config shape at the same time.
* **Session-aware signing.** Sign once and reuse the signature across operations in a session, with a configurable session TTL — plus a read-only signer mode for running the SDK without a signer.
* **React & wagmi integration.** A wagmi v2 compatibility shim (`useConnection` / `getConnection`); decrypted balances persisted to storage, so a page reload no longer re-decrypts behind a spinner; and React SDK audit fixes (consistent imports, an optimistic `shieldETH` flow, documented error handling, a `mergeEnabled` option).
* **WASM thread pool.** `RelayerWeb` (the browser relayer transport) gained a thread-pool option to tune how many worker threads FHE operations use.
* **Integrator-friction & worker fixes.** Smoothed early-integrator rough edges — gas limits, worker bundling, CDN behavior on localhost, React StrictMode restarts, and the Sepolia `/v2` relayer path — and switched the web worker from `importScripts` to fetch-and-eval to fix MIME-type errors. `viem` also became a direct dependency.
* **Security.** Resolved three high-severity Dependabot alerts and the CodeQL code-scanning alerts, and pinned `minimatch` to `10.2.4` to close a ReDoS vulnerability.

## 1.0.1

*Released 2026-03-09.*

A release-plumbing patch with no functional changes — it exists only to trigger a release on top of `1.0.0`. The substance of the initial `1.x` line landed in `1.0.0`; see the [`CHANGELOG.md`](https://github.com/zama-ai/sdk/blob/main/CHANGELOG.md) for that release's full contents.

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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zama.org/protocol/sdk/changelog/legacy/v1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
