@ -32,9 +32,6 @@ Highlights:
* Previously detected RTIO async errors are reported to the host after each kernel terminates and a
warning is logged. The warning is additional to the one already printed in the core device log upon
detection of the error.
* HDF5 options can now be passed when creating datasets with ``set_dataset``. This allows
in particular to use transparent compression filters as follows:
``set_dataset(name, value, hdf5_options={"compression": "gzip"})``.
* Removed worker DB warning for writing a dataset that is also in the archive

calling `ADF5356.init()`.
* DRTIO: Changed message alignment from 32-bits to 64-bits.
* The deprecated ``set_dataset(..., save=...)`` is no longer supported.
* The internal dataset representation was changed to support tracking HDF5 options like e.g.
a compression method. This requires changes to code reading the dataset persistence file
(``dataset_db.pyon``) and to custom applets.

* Experiment classes with underscore-prefixed names are now ignored when ``artiq_client``
determines which experiment to submit (consistent with ``artiq_run``).
