2.0rc1¶

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.
The result folders are formatted “%Y-%m-%d/%H instead of “%Y-%m-%d/%H-%M”. (i.e. grouping by day and then by hour, instead of by day and then by minute)
The parent keyword argument of HasEnvironment (and EnvExperiment) has been replaced. Pass the parent as first argument instead.
During experiment examination (and a fortiori repository scan), the values of all arguments are set to None regardless of any default values supplied.
In the dashboard’s experiment windows, partial or full argument recomputation takes into account the repository revision field.
By default, NumberValue and Scannable infer the scale from the unit for common units.
By default, artiq_client keeps the current persist flag on the master.
GUI state files for the browser and the dashboard are stores in “standard” locations for each operating system. Those are ~/.config/artiq/2/artiq_*.pyon on Linux and C:\Users\<username>\AppData\Local\m-labs\artiq\2\artiq_*.pyon on Windows 7.
The position of the time cursor is kept across experiments and RTIO resets are manual and explicit (inter-experiment seamless handover).
All integers manipulated by kernels are numpy integers (numpy.int32, numpy.int64). If you pass an integer as a RPC argument, the target function receives a numpy type.

1.3¶

1.2¶

No further notes.

1.1¶

TCA6424A.set converts the “outputs” value to little-endian before programming it into the registers.

1.0¶

No further notes.

1.0rc4¶

setattr_argument and setattr_device add their key to kernel_invariants.

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”.
NumberValue now returns an integer if ndecimals = 0, scale = 1 and step is integer.

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).
