> Every version of the SDK, @rekt-trading/1000x, on npm: what is true in it, what it changes for a client, and what to do.

This page lists every version of [`@rekt-trading/1000x`](https://docs.rekt.money/sdk/installation) on npm. Each entry says
what is true in that version, what it changes for a client, and what to do.

## How versions change

The package uses semantic versioning, and its major version is 0.

| Step | What it can change |
| - | - |
| Patch, such as `0.5.1` to `0.5.2` | Behaviour and text. It can add a name. Every exported name and signature stays. |
| Minor, such as `0.5.2` to `0.6.0` | Any exported name, signature or behaviour: added, changed or removed. Its entry says what to change. |

Install the latest version with `npm install @rekt-trading/1000x@latest`.

**0.5.1**

2026-10-28

**Impact for a client: none.** The package exports the same names as 0.5.0.

* `settlementIdentity(market)` returns the label `'benchmark'` for a market whose price feed is of
  kind 2.
* The shipped IDL and `program-constants.json` carry no key of the config authority. Read
  `config.authority` from the chain.
* Its `engines` field says Node 20.10 or later. A fresh install loads on Node 20.19 or later and on
  Node 22.12 or later, and does not load on Node 20.18, 21 or 22.0 to 22.11. `@solana/web3.js`
  (`^1.98.0`) is its one peer dependency.

**Do:** install 0.5.1.

**0.5.0**

2026-10-28

**The first version on npm.**

* ESM only. The package ships compiled modules (`dist/*.js`), their type declarations and the
  program's IDL (`dist/idl.json`).
* It decodes the venue's accounts and events, prices a position as the program does, reports every
  gate that can refuse an action before you send it, and builds the instructions.
* `settlementIdentity(market)` returns a different label for a market whose price feed is of kind 2.

**Do:** install 0.5.1.
