nixtlar 1.0.0

This release consolidates all changes since the last CRAN release (0.6.2), including the development versions 0.6.3 and 0.6.4.

Breaking changes

• nixtlar now requires R (>= 4.1.0).
• Set default value for id_col to unique_id in nixtla_client_historic to match the other core functions.

New features

• Added support for distinguishing between historic and future exogenous variables in the forecasting and cross-validation functions. This feature was available in the development versions 0.6.3 and 0.6.4, but not in the CRAN version (0.6.2).

Bug fixes

• Fixed an HTTP 422 error when using future exogenous variables with h = 1.
  
• Updated internal functions to use the GET method, as the POST method is no longer supported.
• Fixed in-sample timestamp reconstruction in nixtla_client_historic for series that share some but not all in-sample sizes.
  
• Fixed handling of mixed date-only and datetime character ds values that previously produced “failed to parse” warnings and NA timestamps.
  
• Made output date-format detection robust across the whole ds column in nixtla_client_historic, nixtla_client_detect_anomalies, nixtla_client_forecast, and nixtla_client_cross_validation, so a leading midnight value no longer truncates the time component of the remaining rows.

nixtlar 0.6.4

• Development version. Release notes available here.
  
• Added support for distinguishing between historic and future exogenous variables in forecasting and cross-validation functions. Users can now specify which exogenous variables have only historical values and which include both historical and future values.

nixtlar 0.6.2

• Current stable release. Release notes available here.

nixtlar 0.6.1

• Updated to support TimeGPT API v2.
  
• Added support for tibbles, in addition to data frames and tsibbles.
  
• Standardized date format requirements to YYYY-MM-DD or YYYY-MM-DD hh:mm:ss, as character strings or date-time objects.
  
• Default id_col set to unique_id, aligning with the Python SDK. If the dataset contains a single series, id_col=NULL should be used. Only character or integer values are accepted for id_col.
