v0.9.4

• Released snowflake connection and connectors.
• Changed ordering of datasets to be more intuitive (topologically first for CDISC datasets only and then according to input datasets order).
• When closing a teal app (ending a user shiny session), all DataConnections will now try to close their connections.
• Added ADHY keys to configuration file.
• Extended the filter_spec function: the parameter choices is no longer mandatory (the function will take all possible choices by default) and the vars parameter additionally accepts the choices_selected and allows to change the variables for filtering using the UI elements in the encoding panel.
• Cleaned up imports in the package.
• Modified value_choices function to handle edge case when "NA" and NA values exist in the character column that choices are derived from.\
• Fixed issue with cloning Callable class.

v0.9.3

• Support for data-standard independent input and filtering. That includes refactor of the all data and dataset structures together with refactor of FilteredData class.
• New JoinKeys class (with join_keys() constructors and join_key() constructor for its elements) to store joining key columns between datasets.
• Refactored the most basic dataset() constructor, added cdisc_dataset() constructor and as_cdisc() conversion function.
• Soft-deprecate removed class constructors and obsolete functions (e.g. keys()).
• Added get_keys() and set_keys() functions to extract and manipulate datasets primary keys respectively.
• Unexported filtered_data_new, filtered_data_set and filtered_data_set_filters.
• Duplicated lines of code passed to teal::cdisc_dataset and other teal::RelationalDataset constructors should now be shown when getting the code from teal::cdisc_data objects and other teal::RelationalData objects.
• Added ability to press "Enter" key without having to set focus to the Submit button for delayed data loading.
• Allow variable_choices to use datasets with missing labels.
• Fixed bug that ignores input of NULL to selected argument of select_spec function.
• Added button to remove all active filters from the Filter Panel.

v0.9.2

• Added python_dataset_connector to create delayed data objects from python scripts or directly from python code.
• NOTE: python_dataset_connector is not yet ready to be deployed on RSConnect because it does not contain numpy and pandas, which are Python libraries used in python_dataset_connector.
• Added support for filtering on Date and Datetime variables in the Filter Panel.
• Added buttons for date and datetime filter widgets to reset the value to the original.
• Added new function check_key_duplicates, which creates a short summary about rows with duplicated primary key (row numbers and the number of duplicates)
• Fixed lack of labels for character and factor variables in the Filter Panel.
• All variables are now displayed in module_filter_panel, not only those of types numeric, logical, factor, character and Date
• Fixed mutate_data to accept the whole scope of objects for vars.
• Clarified teal::init function documentation to state that custom css loading code with htmltools::htmlDependency should be included in the header argument rather than inside ui arguments of modules.
• Enabled empty select field inside data_extract_spec.
• Added new argument drop_keys to filter_spec to decide whether to drop or keep keys columns on single filter on those columns.
• Added a new optional argument keys to variable_choices. keys specifies the names of the variables, which should have the new key icon shown next to them in the variable drop down menus in the left-hand side encoding panels instead of the icon appropriate for their original R variable type. variable_choices now also works with RelationalDataset and RelationalDatasetConnector objects.
• Removed include_factors option in get_class_colnames in RawDataset.

v0.9.1

• Adds method to resolve nested lists containing delayed data objects, which can be used for arm_ref_comp objects.
• Nested tabs module now has better alignment with the filter panel on the page.
• Allow width argument in optionalSelectInput.
• Added lifecycle badges to all exported functions.
• Added new code_dataset_connector and code_cdisc_dataset_connector functions which enable the creation of new delayed data objects given a string of code.
• Added new functions csv_dataset_connector and csv_cdisc_dataset_connector.
• Updated set_ui_input method of RawDatasetConnector and NamedDatasetConnector to handle user defined shiny inputs.
• Include Keep Inf checkbox for numerical filter items. Keep NA and Keep Inf checkbox doesn't appear if there are no missing or infinite values.
• Replace existing RelationalData class with abstract class RelationalDataCollection and rename RelationalDataList class as RelationalData. The data argument to teal::init is now always a RelationalData object.
• Added fun_cdisc_dataset_connector to enable providing a custom function which returning a dataset.
• Removed code and script arguments from as_relational wrapper. This is intended to be done with mutate_dataset functionality.
• filer argument in init has added a validation step to ensure compatibility with the rest of the app. Variables inherited from ADSL have to be specified only for ADSL dataset.
• Fixes the issue with connection close code not being present in get_code results.
• Fixes the issue of occasional incorrect ordering of bar charts on the filter panel.
• More informative error displayed when pull_fun of DataConnection produces an error.

v0.8.3

• Enable teal app to initialize without data. The data are then loaded from within the teal app.
• New classes (DatasetConnector, DataConnector) to connect to various data sources, including:
  * connector to rice API - rice_cdisc_data and rice_dataset
  * connector to RDS files - rds_data and rds_dataset
• Message appears at bottom right of Shiny app when Shiny is busy to update the views.
• Remove labels argument of cdisc_data function. Labels should now already be present in the data passed to the cdisc_data function. This can be achieved using the var_relabel function.
