openLCA 2.4.1 tar.gz-archive: openLCA_Linux_x64.tar.gz

2.4.1:

• Remove libraries from database (experimental).
• ILCD export: global parameters are only written to a process, when they are used in formulas of that process.
• Fix: corrected display of the connection state in the connection dialog of the graphical editor.
• Fix: flow editor page with regionalized characterization factors crashed sometimes.
• Fix: reference data no longer shows errors during database validation.
• Fix: copy datasets from the library.

2.4.0:

• Fixed allocation factors applied to avoided flows.
• Improved number generation for log-normal distributions.
• Fixed stack overflow in JSON export when providers are included.
• Fixed selection errors in export dialogues.
• Enabled support for longer formulas in dependent parameters.
• Fixed negative results for waste processes in libraries.
• Ensured encrypted libraries can now be used in projects.
• Added support for analysis groups and library fields in the IPC API.
• Introduced analysis groups functionality.
• Updated to Java 21 and Eclipse 4.34.
• Refreshed and updated reference data.

2.3.1:

• Bugfix: Corrected conflict identification when merging commits containing changes to datasets that were also changed locally

2.3:

• Support for the newest CS version & improvements of the CS repository view in openLCA,
• A new tool: Parameter analysis (e.g. time modelling), to run calculations over specific parameter ranges,
• More EPD meta-data for better compatibility with ILCD+EPD,
• Better SimaPro CSV import,
• Three new graphical editors’ themes (Nord Light, Nord Dark and Poimandres).

2.2:

• An updated documentation tab in the process editor, now featuring many more fields for ILCD compatibility, including multiple reviews, compliance declarations, and flow completeness.
• An improved ILCD import (also for EPDs),
• A soda4LCA tool for searching and downloading datasets from soda4LCA online databases (see Tools → soda4LCA andKnown hoststhen for pre-configured database connections),
• Enhanced internationalization of messages, popups, and labels, increasing coverage by 70%. More translations and additional languages will be added soon.
• Bug fixes: the system should no longer crash due to 0-values in product outputs and waste inputs (e.g., in LCA commons). The validation process will now also detect these flows.

2.1.1:

• LCA Collaboration Server:
  • commit empty category,
  • bug fixes.

2.1:

• added a new way to calculate and show social indicators,
• bug fixes in model graph for big process systems,
• several UI improvements (dark mode, …),
• ILCD export for GaBi improved, selection of a pre-filled ILCD template to meet GaBi folder requirements in the import,
• CS bug fix: rename of folders error is now corrected.

2.0.4:

• fix and dark mode design for data quality,
• simplified Chinese translation,
• fix number format preferences,
• faster supply chain deletion in the model graph,
• calculation of regionalized LCIA factors:
  • validation & automatic correction of geometries,
  • testing intersections with locations from the database,
  • merge strategies for calculated factors: replace or keep existing factors,
  • visualization of generated factors per flow,
• database grouping.

2.0.3:

• integration of the Intel Math Kernel Library (MKL),
• convert error to warning when opening a Model Graph due to CSS parsing,
• fix text overlapping on the welcome page,
• display the name of the active DB,
• bug fixes.

2.0.2:

• handling & support for library links in JSON packages,
• Excel export of results: configuration + upstream results,
• export option with providers for JSON packages,
• advanced export configuration for SimaPro CSV,
• better handling of negative characterization factors when impact direction is set,
• impact analysis of processes: show location codes for regionalized system processes,
• rename global parameters: rename them also in cost-formulas,
• parameter usage: show usage in cost formulas in usage tree,
• ILCD import: internal-ids must start with 1,
• library export without inversion (useful for library based databases in cloud services),
• show out-of-memory error when editor crashes for lazy calculations,
• added a function WeightedMeanProvider.of(ResultProvider) for PSILCA raw-value calculation (script will come soon),
• improved dark mode icons.

2.0.1:

• fix on the Sankey diagram (loops),
• fixed a memory leak in the calculation (mainly affects the Monte Carlo simulation),
• “AND” combines words in the search bar,
• remove the process contribution from the report for now as they are available in the project result display,
• fix on the JSON export (multiple global parameters with the same name),
• display direct contributions in the upstream tree,
• updates of the IPC API,
• bug fixes.
