I’m announcing version 2.0.0 of the **{ecmwfr} R package** providing native R access to the Data Store products. The package now uses the latest `beta` API, which is set to replace the current one mid September. You can update using:

```r
install.packages("ecmwfr")

```

Please update your _R_ code in time to guarantee continued functionality. Please read the release note (blog post) carefully as there are some breaking changes to the API and more importantly to the data formats.

> Updating API service hooks and some critical notes

Although this release addresses some issues, including collisions between login credentials, the package is limited by the current API issues highlighted elsewhere on the forum such as [data formatting](https://prod.ecmwf-forum-prod.compute.cci2.ecmwf.int/t/changes-to-grib-to-netcdf-converter-on-cds-beta-ads-beta/4322) and [no full index of API functionality](https://prod.ecmwf-forum-prod.compute.cci2.ecmwf.int/t/is-the-new-api-going-to-be-documented/4557).

For those on other frameworks (.NET etc), feel free to go through the package code. It might help you migrate to the new API.
