umweltapir 0.2.1

Operating systems which do not use UTF-8 as default lead to errors in the fetch functions, so the functions were changed to ensure correct encoding.

umweltapir 0.2.0

This version is not fully compatible with the prior version due to differences in the JSON schema and Arrow IPC serialization.

Use Arrow IPC serialization format for building data-frame-like output to increase performance: The umwelt.info streaming endpoints /search/all and /dataset/all now support Arrow IPC in addition to ND-JSON. Using Arrow IPC, the output is returned as a tibble.
Use column-selection API to reduce network traffic: The umwelt.info streaming endpoints /search/all and /dataset/all now support reducing the amount of transmitted data by choosing which columns to serialize.
