OpenML 1.10 (Release date: 2019-09-22):
===========
- Avoid nameclashes with mlr3 by moving ParamHelpers to Suggests
- Force using httr 1.4.1 and curl 4.1
OpenML 1.9 (Release date: 2019-08-06):
===========
- Fixed bug: Uploaded runs now also contain default hyperparamters.
- Fixed bug with multiple values for ignore.attribute.
- The status argument of listOML* functions can now also take the value 'all'.
- Allow to uploading data sets with multiple targets (e.g. multilabel tasks).
- New functions: uploadOMLTask, uploadOMLStudy, makeOMLStudy, getOMLStudy, listOMLStudies, extractOMLStudyIds.
OpenML 1.8 (Release date: 2018-03-02):
===========
- Fixed bug in listOMLSetup.
- Update to curl 3.1 which fixes the error 'transfer closed with outstanding read data remaining' for large files.
- New function extractOMLStudyIds added, which directly extracts ids of data sets, tasks, flows and runs.
OpenML 1.7 (Release date: 2017-10-17):
===========
- listOMLTask, listOMLFlow, listOMLRuns do not return the tag field anymore.
- New function listOMLSetup added, which enables extracting hyperparameter configurations of specific setups/flows.

OpenML 1.4 (Release date: 2017-06-20):
===========
- Bugfix: Error message "Start tag expected, '<' not found" for getOMLTask and getOMLDataSet was fixed.
- as.data.frame methods for OMLRunParList, OMLDataSet and OMLTasks objects were added.
- listOMLRunEvaluations now allows to get results w.r.t. a single evaluation measure ('evaluation.measure' arg) which speeds up the request.
- listOMLRuns and listOMLRunEvaluations now also supports a vector of ids for task.id, flow.id and uploader.id.
- getOMLRun(run.id, only.xml = TRUE) can now be used to get the run without the predictions arff file (which is faster, especially when you are only interested in, e.g. getting the hyperparameters of a run).

- listOMLTasks and listOMLDataSets now additionally show a message when the limit of results is reached.
- listOML* functions return an empty data frame when no results are available.
- listOMLRunEvaluations now returns additional columns for the flow (flow version, flow source and learner name).
- runTask now allows to set the 'models' option to FALSE so that resulting objects will be smaller.
OpenML 1.2 (Release date: 2017-02-07):
