Release notes
=============
unreleased [2.x]
----------------
* The format of the influxdb pattern file is simplified. The procedure to
edit patterns is also changed to modifying the pattern file and calling:
``artiq_rpctool.py ::1 3248 call scan_patterns`` (or restarting the bridge)
The patterns can be converted to the new format using this code snippet::
from artiq.protocols import pyon
patterns = pyon.load_file("influxdb_patterns.pyon")
for p in patterns:
print(p)
* The "GUI" has been renamed the "dashboard".
* When flashing NIST boards, use "-m nist_qcX" or "-m nist_clock" instead of
just "-m qcX" or "-m clock" (#290).
* Applet command lines now use templates (e.g. $python) instead of formats
(e.g. {python}).
* On Windows, GUI applications no longer open a console. For debugging
purposes, the console messages can still be displayed by running the GUI
applications this way::
python3.5 -m artiq.frontend.artiq_browser
python3.5 -m artiq.frontend.artiq_dashboard
(you may need to replace python3.5 with python)
Please always include the console output when reporting a GUI crash.
* Closing the core device communications before pausing is done automatically.
Experiments no longer need to do it explicitly.
unreleased [1.0rc3]
-------------------
* The HDF5 format has changed.
* The datasets are located in the HDF5 subgroup ``datasets``.
* Datasets are now stored without additional type conversions and annotations
from ARTIQ, trusting that h5py maps and converts types between HDF5 and
python/numpy "as expected".
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).
