## BREAKING

- Switch from [ncb000gt/node-cron](https://www.npmjs.com/package/cron) to [harrisiirak/cron-parser](https://www.npmjs.com/package/cron-parser) for cron-pattern parsing. See issue ([#475](https://github.com/kelektiv/node-cron/issues/475))

      Previously month was 0-based (0=January). Going forward standard Unix pattern is used, which is 1-based (1=January).

      Please update existing cron-patterns that specify a month (4th position of a pattern). The month is now 1 - 12

      1 = January

      2 = February

      3...

      | Example | Execute on 1st of January |
      |---------|---------------------------|
      | Old     | 0 0 1 **0** *             |
      | New     | 0 0 1 **1** *             |

      ([#1150](https://github.com/agenda/agenda/pull/1150))

      old Cron patterns

      ```
      * * * * * *
      | | | | | |
      | | | | | +-- Year              (range: 1900-3000)
      | | | | +---- Day of the Week   (range: 1-7, 1 standing for Monday)
      | | | +------ Month of the Year (range: 0-11) NOTE: Difference here
      | | +-------- Day of the Month  (range: 1-31)
      | +---------- Hour              (range: 0-23)
      +------------ Minute            (range: 0-59)
      ```

      new cron patterns

      ```
      * * * * * *
      | | | | | |
      | | | | | +-- Day of the Week   (range: 0-7, 0 or 7 is Sunday)
      | | | | +---- Month of the Year (range: 1-12) NOTE: Difference here
      | | | +------ Day of the Month  (range: 1-31)
      | | +-------- Hour              (range: 0-23)
      | +---------- Minute            (range: 0-59)
      +------------ Second            (range: 0-59, optional)
      ```

  # 2.0.0 / 2018-07-19

  - Rewrite tests: replace `mocha` and `blanket` with `ava` and `nyc` ([#506](https://github.com/agenda/agenda/pull/506))

  - Fixes some flaky tests
  - Adds docs generator (`npm run docs` to generate `/docs`)

## BREAKING

- Rewrite Agenda API support promises! ([#557](https://github.com/agenda/agenda/pull/557))

  No more callbacks! Instead of:

  ```js
  function graceful() {
    agenda.stop(function () {
      process.exit(0);
    });
  }
  ```

  You need to:

  ```js
  async function graceful() {
    await agenda.stop();
    process.exit(0);
  }
  ```

  You don't anymore have to listen for `start` event. Instead you can do:

  ```js
  await agenda.start();
  agenda.every("10 minutes", "example");
  ```

  However, this will still work:

  ```js
  agenda.on("ready", function () {
    agenda.every("10 minutes", "example");
    agenda.start();
  });
  ```

  See the documentation for more!

## BREAKING

- Fix jobs not running in order of them being queued ([#464](https://github.com/agenda/agenda/pull/464))

- Changes in Cron string parsing, changed parsing library from [ncb000gt/node-cron](https://www.npmjs.com/package/cron) to [harrisiirak/cron-parser](https://www.npmjs.com/package/cron-parser) ([#475](https://github.com/agenda/agenda/pull/475))

Previously Agenda would treat months as 0-11 where as normally, cron months are parsed as 1-12.

```
* * * * * *
| | | | | |
| | | | | +-- Year              (range: 1900-3000)
| | | | +---- Day of the Week   (range: 1-7, 1 standing for Monday)
| | | +------ Month of the Year (range: 0-11) NOTE: Difference here
| | +-------- Day of the Month  (range: 1-31)
| +---------- Hour              (range: 0-23)
+------------ Minute            (range: 0-59)
```

Starting in version `1.0.0`, cron will be parsed in the standard UNIX style:

```
* * * * * *
| | | | | |
| | | | | +-- Year              (range: 1900-3000)
| | | | +---- Day of the Week   (range: 1-7, 1 standing for Monday)
| | | +------ Month of the Year (range: 1-12) NOTE: Difference here
| | +-------- Day of the Month  (range: 1-31)
| +---------- Hour              (range: 0-23)
+------------ Minute            (range: 0-59)
```
