    systems it seems that it reports uptime nanoseconds, not epoch nanoseconds. Fixes
    #86. #88

• Fixed

  • Math error in GPIO debounce calculation, multiplied when I should have divided. Also
    corrects cast error in CDev interrupt where epoch nanoseconds (1.6×10¹⁵)
    is cast to a 32-bit integer (max 2.15×10⁹). Fixes #85. #87

v0.12.1

• Changed

  • Config parser no long converts selection keys to strings before matching. #82

• Added

  • Config parser now considers required sections with defaults for all options to be

  • Config parser was reporting valid configuration for optional conditional sections
    containing invalid values. Fixes problem 1 in #80. #81
  • YAML returning booleans for unquoted on or off strings, booleans have been
    added as accepted values where applicable to avoid confusion. Fixes #80. #82

v0.12.0

Major Core Rewrite

This release is a big one! The core functionality has been almost completely rewritten
in order to make things a lot simplier for modules. There is now a standardized message
bus that modules use, instead of calling functions directly in other modules. This
abstraction also paves the way for adding other communication modules. However, as with
anything, there was a price; a lot of things have changed and a few features were dropped.

One of the major goals of this rewrite is to bring Homie support to MQTTany (Homie support
itself is not yet added). In order to do that it was necessary to abstract the way interface
modules connect to communication modules. This means that interface modules must now
provide more details on the data they export, but can no longer directly specify topics.

Internally the new message bus largely resembles the Homie convention in order to have all
details required for it. This means that topics must now have a minumum depth of 2 (ex.
{node}/{property}, gpio/1) and absolute topics are no longer supported.

Due to the number of changes, you will need to go over the documentation for each module
you are using and update your configuration file to work with the new options and changes.
If you were using default MQTT topics you will likely not have to change your home
automation setup much in order to interface with this version of MQTTany.

• BREAKING CHANGE

  • Absolute and custom topic support removed. This means all topic options in config
    will now be ignored. See the documentation for each module to see how paths work. #49
  • GPIO - Digital pins now report their state as ON or OFF. #49
  • GPIO - Digital pins no longer support time only or comma separated messages for
    pulse commands, only JSON is supported now. #49
  • I2C - MCP230xx pins now report their state as ON or OFF. #49
  • I2C - MCP230xx pins no longer support time only or comma separated messages for
    pulse commands, only JSON is supported now. #49
  • LED - Options specific to output methods are now in a nested section inside the
    array definition. See the documentation for details. #49
  • LED - Animations can only be called with JSON on path {array_id}/animation/set. #49
  • OneWire - Options specific to devices are now in nested sections inside the device
    definition. See the device documentation for details. #49
  • LED - Move the fps option from module config to array config allowing per-array
    FPS setting. This is now published when the array is setup also. #52
  • GPIO - Change language for direction to pin mode to be less specific and lay
    ground work for additional pin modes. #55
  • GPIO - move interrupt, invert, and initial settings into a digital
    subsection in config. This was done to align with the new counter pin type to
    distinguish which pin type these settings apply to. #78

• Added

  • Colorized log output to terminal.
  • .pylintrc file.
  • GitHub Actions for pylint and black checks.
  • Python version check before importing anything with a minimum version requirement. #49
  • Import checking for the core requirements with log entries for missing packages. #49
  • Template modules and documentation to help with creating new modules. #49
  • Config file version key. This will prevent MQTTany from running with an outdated
    config file that may cause errors or strange behavior. Config version number will
    incriment when incompatible changes occur in the config format. #50
  • Config option flag secret to obfuscate values in the log for passwords, etc. #53
  • I2C - If bus is a number, checks for path /dev/i2c{bus} as well as
    /dev/i2c-{bus} now. #62
  • udev rule files to help with hardware permissions. #63
  • GPIO - support for OrangePi Zero boards. #71
  • GPIO - support for counter pins. #75
  • Config option conditions allows matching a key at the same level to a value.
    Useful for sections or options that are required only for certain modes. #77
  • Update all modules to use config conditions. #78

• Changed

  • Convert all string formatting to use f-strings. This change means you must be using
    a minimum Python version of 3.6. #49
  • Convert all logging to use lazy formatting. This should save some time building log
    messages for disabled log levels. #49
  • Logger get_module_logger now uses entire module name after modules instead of
    only selecting the element after the last period. #49
  • Move mprop requirement up into core, now modules don't need to make sure it is
    installed. #49
  • MQTT - Messages arriving on {node}/{property}/+/# will match and the callback
    for the property will be called. The callback should further inspect the topic before
    taking action. #49
  • LED - Remove the modified version of libsacn that was bundled with the LED module.
    The needed modifications are now available upstream in version 1.4.5. #51
  • Updated Adafruit Platform Detect version from 1.x to 2.x. #54
  • Consolidate get_module_logger and get_logger into single function and remove
    leading mqttany from all logger names. #56
  • log_traceback now formats entire traceback into a single log entry on a new line,
    like a standard stack trace. #66
  • GPIO access has been moved into the core, allowing all modules access to GPIO pins
    as needed. #64
  • GPIO access is now acheived using the periphery library via the new cdev
    interface, with a fallback to the older sysfs access. This moves MQTTany away
    from the now depreciated wiringpi library and opens the door for easy support
    of any SBC that supports cdev or sysfs GPIO access. #64

• Fixed

  • Remove requirements file for old MCP230xx module that was removed in v0.10.0.
  • Fix logger checking if TRACE logging was enabled for WARN messages.
  • Core not exiting correctly if an exception occurred in the core. #49
  • Logging not truncating process name or logger name, this could have resulted in
    misaligned log entries. #56
  • LED - fix error on unload if array animation manager was never started. #67
  • LED - fix permission check for non-SPI outputs on Raspberry Pi arrays. #68

v0.11.0

• Added

  • XSET module to allow sending xset commands to control screensaver,
    screen power options, etc.

• Changed

  • Begin using Python Black code formatter. This has resulted in a massive commit as
    there are changes to most files. All changes made by Black have been reviewed and
    no errors were found.

• Fixed

  • MQTT not handling absolute topics correctly.
  • Incorrect reference to rpiGPIO in ODroid GPIO interface.
