    • the is_invalid column is now reported as is_valid
  • Changes to LTP:
    • renamed loading and storage columns

  • Changes to JSON:
    • json_v1 and json_v2 has been removed.

Experimental features​

  • Add maximum power limit for compressor models

Breaking changes​

Some breaking changes are needed to keep improving eCalc, remove ambiguity and prepare eCalc for the future:

YAML​

  1. All component names must be unique to avoid ambiguity in reporting
  2. UNITS are required when setting up compressor and pump charts
  3. Restrict allowed characters in component names and emission names
  4. NAME no longer used for LTP reporting, use CATEGORY instead
  5. Not possible to use custom category names, pre-defined categories must be uppercase with hyphen as separator (i.e. FUEL-GAS)

CLI​

  1. Invoking eCalc™ directly is no longer supported, use ecalc run instead.
  2. Log level should be specified as the first argument + log to file
  3. Model yaml-file needs to come last
  4. Extrapolation (correction) is now always used and cannot be disabled
  5. Argument for LTP export has changed from: --centuries-ltp-export to --ltp-export
  6. Simple results are now default for json
