Release notes
=============
unreleased [1.0rc3]
-------------------
* The HDF5 format has changed. The datasets are located in the subgroup ``datasets``.
1.0rc2
------
* The CPU speed in the pipistrello gateware has been reduced from 83 1/3 MHz to
75 MHz. This will reduce the achievable sustained pulse rate and latency
accordingly. ISE was intermittently failing to meet timing (#341).
* set_dataset in broadcast mode no longer returns a Notifier. Mutating datasets
should be done with mutate_dataset instead (#345).
1.0rc1
------
* Experiments (your code) should use ``from artiq.experiment import *``
(and not ``from artiq import *`` as previously)
* Core device flash storage has moved due to increased runtime size.
This requires reflashing the runtime and the flash storage filesystem image
or erase and rewrite its entries.
* ``RTIOCollisionError`` has been renamed to ``RTIOCollision``
* the new API for DDS batches is::
with self.core_dds.batch:
...
with ``core_dds`` a device of type ``artiq.coredevice.dds.CoreDDS``.
The dds_bus device should not be used anymore.
* LinearScan now supports scanning from high to low. Accordingly,
its arguments ``min/max`` have been renamed to ``start/stop`` respectively.
Same for RandomScan (even though there direction matters little).
