Changelog

All notable changes to this project will be documented in this file.

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

[Unreleased]

[0.2.6] - 2024-09-25

  • Fixed rounding in dynamic_lcia to avoid duplicate entries in dynamic inventory

[0.2.5] - 2024-09-25

  • Added rounding to 3 decimal places for interpolation weights

[0.2.4] - 2024-09-24

  • Added support for passing Node objects to bw_timex.utils.get_exchange and bw_timex.utils.add_temporal_distribution_to_exchange.

[0.2.3] - 2024-09-22

  • Modified the date rounding behavior: Instead of always rounding off the dates in the timeline (using the resolution specified in temporal_grouping), we now round to the nearest year/month/day/hour (depending on temporal_grouping).
  • Fixed interface to dynamic_characterization (see https://github.com/brightway-lca/dynamic_characterization/releases/tag/v1.0.0) and pinned version to >=1.0.0.

[0.2.2] - 2024-09-18

  • Added optional starting_datetime argument to TimexLCA.build_timeline explicitly. Before, it was buried in *args, which were passed to the underlying graph traversal (#93)
  • Allow multiple calls of build_timeline using the same TimexLCA object, e.g., using different starting_datetime (#94)
  • Fixed unintuitive rounding down of timestamps in dynamic characterization. 2024-12-31 would have been rounded to 2024, whereas 2025 makes more sense here. Now we round to the nearest year (https://github.com/brightway-lca/bw_timex/commit/21fa55bbcafee196447840c6518b5fee49fb6660)

[0.2.1] - 2024-09-16

  • Added labels and units to the y-axis in TimexLCA.plot_dynamic_characterized_inventory()
  • Fixed functions for creating labelled matrix representations

[0.2.0] - 2024-09-13

  • Added utility function utils.add_temporal_distribution_to_exchange() for easier temporalization of existing models
  • Added more clarifying docstrings, created a "Getting Started" section in the docs as well as a getting_started.ipynb. Also overhauled existing example notebooks.
  • Changed naming of the different score attributes to be more clear and turned them into a @property:
    • TimexLCA.base_score := TimexLCA.static_lca.score (no time-explicit information)
    • TimexLCA.static_score := TimexLCA.lca.score (time-explicit LCI w/ static characterization)
    • TimexLCA.dynamic_score := TimexLCA.characterized_inventory["amount"].sum() (time-explicit LCI w/ dynamic characterization, summed overall score)
  • Fixed amounts for negative production amounts (#83)

[0.1.9] - 2024-08-09

  • Allow absolute temporal distributions (#81)

[0.1.8] - 2024-07-17

[0.1.7] - 2024-07-11

  • Fixed some dependencies

[0.1.6] - 2024-07-11

  • Performance improvements
  • Added option to calculate the dynamic LCI directly from the timeline without expanding the technosphere matrix

[0.1.5] - 2024-06-28

[0.1.4] - 2024-06-15

  • Handled emissions occurring outside of fixed time horizon in dynamic characterization #46
  • Fix substitution exchanges #53
  • Fix non-unitary production exchanges #55

[0.1.3] - 2024-06-07

  • Renamed repo and package to bw_timex
  • Fixed error in dynamic characterization if IDs were stored as flow identifiers in methods

[0.1.2] - 2024-05-27

  • Update to match Bugfix in bw_temporalis v1.1: static_activity_indices are database IDs instead of matrix IDs

[0.1.1] - 2024-05-05

  • Improved user-friendliness for SETAC

[0.1.0] - 2024-04-29

  • Initial version with core functionalities
