MBusinoLib change log

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[0.9.20] - 2026-04-28

Changed

  • Renamed a_field to address in decodeHeader() JSON output

[0.9.19] - 2026-04-25

Changed

  • Renamed decode() to decodeRecords() for clarity (old name kept as deprecated wrapper)

  • revised Example

[0.9.18] - 2026-04-23

Added

  • New decodeHeaderLong() method: decodes M-Bus Long Frame header (ID, manufacturer, medium, status byte, version, access counter, signature) into a JSON object
  • Example updated to demonstrate header decoding

[0.9.17] - 2026-03-21

Changed

  • Buffer overflow prevention: increased vifBuffer and charBuffer sizes by 1 byte
  • Typo fix: LUMINOUS_IDENSITY_CD → LUMINOUS_INTENSITY_CD
  • UNKNOWN_VIF no longer returns "total" as state_class
  • Formatting: unified indentation to 4 spaces

[0.9.14] - 2025-05-29

Changed

  • fix an issue if CRC is randomly a MDH (0Fh/1Fh)

[0.9.13] - 2025-05-26

Added

  • support of first nibble F marked negative BCDs [outside the standard]
