ARTIQ-5 is released today. To update, follow the stable branch manual at https://m-labs.hk/artiq/manual/installing.html.
Highlights of this new release (compared to 4.0):
- Performance improvements:
- Improved packaging and build system:
- new continuous integration/delivery infrastructure based on Nix and Hydra,
providing reproducibility, speed and independence.
- rolling release process (https://github.com/m-labs/artiq/issues/1326).
- firmware, gateware and device database templates are automatically built for all
supported Kasli variants.
- new JSON description format for generic Kasli systems.
- Nix packages are now supported.
- many Conda problems worked around.
- controllers are now out-of-tree.
- split packages that enable lightweight applications that communicate with ARTIQ,
e.g. controllers running on non-x86 single-board computers.
- Improved Urukul support:
- AD9910 RAM mode.
- Configurable refclk divider and PLL bypass.
- More reliable phase synchronization at high sample rates.
- Synchronization calibration data can be read from EEPROM.
- A gateware-level input edge counter has been added, which offers higher
throughput and increased flexibility over the usual TTL input PHYs where
edge timestamps are not required. See artiq.coredevice.edge_counter for
the core device driver and artiq.gateware.rtio.phy.edge_counter/
artiq.gateware.eem.DIO.add_std for the gateware components.
- With DRTIO, Siphaser uses a better calibration mechanism.

- Schedule updates can be sent to influxdb (artiq_influxdb_schedule).
- Experiments can now programatically set their default pipeline, priority, and flush flag.
- List datasets can now be efficiently appended to from experiments using
artiq.language.environment.HasEnvironment.append_to_dataset.
- The core device now supports IPv6.
- To make development easier, the bootloader can receive firmware and secondary FPGA
gateware from the network.
- Python 3.7 compatibility (Nix and source builds only, no Conda).
- Various other bugs from 4.0 fixed.
- Preliminary Sayma v2 and Metlino hardware support.
Breaking changes:
- The
artiq.coredevice.ad9910.AD9910 and
artiq.coredevice.ad9914.AD9914 phase reference timestamp parameters
have been renamed to ref_time_mu for consistency, as they are in machine
units.
- The controller manager now ignores device database entries without the
"command" key set to facilitate sharing of devices between multiple
masters.
- The meaning of the
-d/--dir and --srcbuild options of artiq_flash
has changed.
- Controllers for third-party devices are now out-of-tree.
aqctl_corelog now filters log messages below the WARNING level by default.
This behavior can be changed using the -v and -q options like the other
programs.- On Kasli the firmware now starts with a unique default MAC address
from EEPROM if mac is absent from the flash config.
- The
-e/--experiment switch of artiq_run and artiq_compile
has been renamed -c/--class-name.
artiq_devtool has been removed.- Much of
artiq.protocols has been moved to a separate package sipyco.
artiq_rpctool has been renamed to sipyco_rpctool.
artiq_ctlmgr and the influxdb tools have moved to a separate package artiq-comtools (normally installed by default).
