# CHANGELOG

## 1.4.5

- Pump superagent to `10.1.1`, fixed a public vulnerability with formidable dependency.

## 1.4.4

- Pump scryptlib to `2.2.5`
- 
## 1.4.3

- Pump scryptlib to `2.2.4`

## 1.4.0

- just republish with ci

## 1.3.34

- pump scryptlib
- remove `bsv` lib, use `@scrypt-inc\bsv` lib
- add `random` function for `TestWallet`

## 1.3.31

**Breaking Change**

Remove `connect(provider: Provider)` function of the signer. You don't need to call `signer.connect(provider)`. 

The contract instance only needs to be connected to a signer:

```ts
const counter = new Counter(1n);
const signer = new TestWallet(
        myPrivateKey,
        new DefaultProvider()
    )
await counter.connect(signer);
```


## 1.3.22

- fix getNetWork


## 1.3.21

- fix connect
- update `DummyProvider` fee


## 1.3.20

- multi call Use respective signer 

## 1.3.19

- Fix #482


## 1.3.18

- support panda 2.0

## 1.3.17

- optimizing defaultProvider
- add `getOffchainUpdates()` to `SmartContract`
  
**breaking change**
  
- remove `offchainUpdates` of `SmartContract`



## 1.3.16

- add `PandaSigner`
- implement the following functions in `abstract` Signer:
  
  1. `signRawTransaction`
  2. `signTransaction`




## 1.3.14

- TAAL and GorillaPool providers fetch current fee rate upon connect.
- WoC provider - lowered fee rate to 1 sat / KB.


## 1.3.13

1. support override `this.lockingScript`
2. support override `this.init()`

## 1.3.10

- rename `setConstructor()` to `init()`

## 1.3.9

  **example:**

  ```ts
    const demo = new Demo(1n, 2n)

    // connect to a signer
    await demo.connect(getDefaultSigner())

    const nopScript = bsv.Script.fromASM("OP_FALSE OP_IF ... OP_ENDIF");

    demo.prependNOPScript(nopScript)

    // contract deployment
    const deployTx = await demo.deploy(1)
    console.log('Demo contract deployed: ', deployTx.id)

    // create instance from transaction
    let currentInstance = Demo.fromTx(deployTx, 0, {}, nopScript);

  ```


- add build-ins function `this.timeLock()`， see https://docs.scrypt.io/tutorials/timeLock
  
  **example:**

  ```ts
  assert(this.timeLock(this.locktime0), 'time lock for locktime0 failed')
  ```
 

## 1.3.8

- augment bsv types with  `.toByteString()`
- change domain specific byte types to take `ByteString` as init. param instead of `Bytes`

## 1.3.5

**example:**

```ts
  const demo = new Demo(1n, 2n)

  // connect to a signer
  await demo.connect(getDefaultSigner())

  demo.setOrdinal({
      content: toByteString("hello, this is demo contract.", true),
      contentType: "text/plain"
  })

  // contract deployment
  const deployTx = await demo.deploy(1)
  console.log('Demo contract deployed: ', deployTx.id)
```
