Highlights: Highlights:
* Hardware support: * New hardware support:
- Support for Shuttler, a 16-channel 125MSPS DAC card intended for ion transport.
Waveform generator and user API are similar to the NIST PDQ.
- Implemented Phaser-servo. This requires recent gateware on Phaser. - Implemented Phaser-servo. This requires recent gateware on Phaser.

variant. - Metlino and Sayma support has been dropped due to complications with synchronous RTIO clocking.
- More user LEDs are exposed to RTIO on Kasli.
- Implemented Phaser-MIQRO support. This requires the proprietary Phaser MIQRO gateware
variant from QUARTIQ.

Breaking changes:
* ``SimpleApplet`` now calls widget constructors with an additional ``ctl`` parameter for control
operations, which includes dataset operations. It can be ignored if not needed. For an example usage,
refer to the ``big_number.py`` applet.
* ``SimpleApplet`` and ``TitleApplet`` now call ``data_changed`` with additional parameters. Derived applets
should change the function signature as below:
::
# SimpleApplet
def data_changed(self, value, metadata, persist, mods)
# SimpleApplet (old version)
def data_changed(self, data, mods)
# TitleApplet
def data_changed(self, value, metadata, persist, mods, title)
# TitleApplet (old version)
def data_changed(self, data, mods, title)
Accesses to the data argument should be replaced as below:
::
data[key][0] ==> persist[key]
data[key][1] ==> value[key]
* The ``ndecimals`` parameter in ``NumberValue`` and ``Scannable`` has been renamed to ``precision``.
Parameters after and including ``scale`` in both constructors are now keyword-only.
Refer to the updated ``no_hardware/arguments_demo.py`` example for current usage.
* Almazny v1.2 is incompatible with the legacy versions and is the default.
To use legacy versions, specify ``almazny_hw_rev`` in the JSON description.
* Legacy PYON databases should be converted to LMDB with the script below:

refer to the ``big_number.py`` applet.
* ``SimpleApplet`` and ``TitleApplet`` now call ``data_changed`` with additional parameters. Wrapped widgets

def data_changed(self, value, metadata, persist, mods)
# SimpleApplet (old version)

def data_changed(self, data, mods, title)
Old syntax should be replaced with the form shown on the right.

Parameters after and including ``scale`` in both constructors are now keyword-only.
Refer to the updated ``no_hardware/arguments_demo.py`` example for current usage.
* ``artiq_ddb_template`` requires latest generic Kasli gateware to function properly
due to RTIO channel renumbering.
