Changes

0.11 (2024-05-03)

• Frame exception updates; See below. The new_exceptions parameter has been removed from the Frame() constructor and the Frame.pack_len() method.
• Method to control the power supply in the Lunatone DALI USB 30ma added to dali.driver.hid.tridonic [mbecker]
• Improved support for colour-control devices (device type 8) [jktjkt]
• Driver for Lunatine SCI RS232 [opieters]
• Driver for AL-DALI-HAT [rijimuge]
• Bug fixes to input device support [jktjkt]

Frame exception updates

The exceptions raised by dali.frame.Frame() and the Frame.pack_len() method are changing. In release versions <= 0.8, if you pass an invalid sequence to initialise a Frame a TypeError will be raised. In release 0.9 this changed to ValueError. If you pass an invalid length to pack_len(), currently a ValueError will be raised. In release 0.9 this changed to OverflowError.

To obtain the new behaviour when using release 0.8, pass new_exceptions=True to Frame() and pack_len(). In release 0.9, you can to continue to obtain the old behaviour by passing new_exceptions=False. In the release after that (provisionally "0.10"), passing any value for new_exceptions will issue a warning and in the release after that, the new_exceptions keyword argument will be removed.

The new behaviour makes the library more consistent with the exceptions raised by the native int.from_bytes() and int.to_bytes() methods.

0.10 (2022-10-24)

• Python 3.6 is no longer supported.
• Frame exception updates; see above. The old behaviour is no longer available and passing new_exceptions when calling the Frame() constructor or the Frame.pack_len() method will issue a warning.
• The dali.address classes for gear and devices have been separated. dali.address.Short() has been split into dali.address.GearShort() and dali.address.DeviceShort(); similar changes have been made to Group(), Broadcast() and BroadcastUnaddressed(). The old names are still present and usable for gear, and there is no plan to remove them. [sl-wallace]
• The 24-bit command support in dali.device.general has been improved: commands now have appropriate Response types. This code has now been tested against real hardware. [sl-wallace]
• The memory subsystem now supports access to the memory banks of 24-bit control devices as well as 16-bit control gear. [sl-wallace]
• 24-bit event messages are supported. [sl-wallace]
• Support has been added for pushbutton devices (IEC 62386 part 301). [sl-wallace]
• 24-bit frame support has been added to the async Tridonic driver. [sde1000]
• A driver has been added for Lunatone LUBA serial DALI interfaces. [sl-wallace]
• Support for colour devices (device type 8) has been added. [sl-wallace / Petr Ilgner]
• Support for occupancy sensors (IEC 62386 part 303). [sl-wallace]
• Support for light sensors (IEC 62386 part 304). [sl-wallace]

0.9 (2022-04-21)

• Command._devicetype, Command.is_config and Command._response have been removed. (They were deprecated in release 0.7.)
• Frame exception updates; see above. The new behaviour is now the default, and the old behaviour can be accessed by passing new_exceptions=False when calling the Frame() constructor and the Frame.pack_len() method.
• Updated the Hasseb driver to use a more generally available HID library [dgomes]

0.8 (2021-12-02)

• Memory bank subsystem: command sequences to access and interpret the contents of memory banks [ferdinandkeil, sde1000]
• Frame exception updates; see above. The new behaviour can be accessed in this release by passing new_exceptions=True when calling the Frame() constructor and the Frame.pack_len() method.
• Driver updates [jbaptperez, awahlig, rousveiga, rnixx]

0.7.1 (2020-09-02)

• Remove unused problematic imports from dali.driver.hasseb [dgomes]

0.7 (2020-08-10)

• Frame improvements: add pack_len() method and simplify str(BackwardFrame()) output
• Add Response.raw_value attribute to Response objects to give access to the underlying BackwardFrame of the response (or None if no response was received)
• Add NumericResponse and NumericResponseMask classes and make use of them where appropriate
• Rename some Command class attributes, removing the initial _ to indicate that they are public. The API now supports Command.response, Command.devicetype, Command.uses_dtr{0,1,2}, Command.inputdev and Command.appctrl attributes.
• Add support for "sequences" of commands that implement higher-level operations. Initial sequences include commisioning of control gear (discovering bus units and assigning short addresses), reading the list of device types, querying and setting group membership.
• Remove the obsolete dali.bus module; all of the useful code from it is now implemented as sequences
• 4–5× performance improvement of the command.from_frame() function
• Remove support for Python 2
• Some driver additions and changes [sde1000, hasseb, mhemeryck]

0.6 (2018-11-11)

• Python 3 fix in async Tridonic driver [jjonek]
• Updated Hasseb driver [dgomes]

0.5 (2017-05-15)

• Move tests to dedicated package. [rnix]
• Rename dali.device.Device._addressobj to dali.device.Device.address_obj since it is used as API in dali.command.Command. [rnix]
• Move dali.device.Device class to dali.bus, dali.device module has been removed which conflicted with dali.device package. [rnix]
• Add dali.exceptions module and move all DALI related exceptions to it. [rnix]
• Move dali.interfaces to dali.drivers.daliserver. [rnix]
• Update Package structure documentation. [rnix]

0.4 (2017-03-19)

• PyPI support [dgomes]

0.3

• Python 3 support [sde1000]

0.2

• Introduce basic sync and async drivers. [rnix]
• Basic implementation of LUNATONE Dali USB driver. [rnix]

0.1

• Initial release. [sde1000]
