• Only list each coordinate once (per category) in pgfplots scatter plots (Paul Höft).

v8.4 (2025-02-11)

Lab

• Allow fetching from compressed properties files (Jendrik Seipp).
• Use absolute paths in Slurm scripts to safeguard against .bashrc changing directories (Jendrik Seipp).
• Use 9 GiB memory limit for Slurm jobs on Tetralith by default (Jendrik Seipp).
• Revise documentation about memory limits (Jendrik Seipp).
• Remove soft memory limit from Slurm jobs that used to guard against an old problem of the cgroup mechanism failing (Jendrik Seipp).
• Remove documentation about obsolete infai_1 partition in Basel (Florian Pommerening).

• Raise minimum supported Python version to 3.8 (Jendrik Seipp).

Downward Lab

• Add add_compress_exp_dir_step() to example Fast Downward experiment (Jendrik Seipp).

v8.3 (2024-10-22)

Lab

• Add support for Python 3.12 and 3.13 (Jendrik Seipp).
• Run parser functions in run directories (Jendrik Seipp).

Downward Lab

• Gracefully handle missing planner exit codes in driver.log (Jendrik Seipp).

v8.2 (2024-05-06)

Lab

• Gracefully handle programs that write garbled output by replacing problematic characters (Jendrik Seipp).
• Add parsing errors to properties file directly instead of writing them to stderr (Jendrik Seipp).
• Remove special treatment of Slurm "memory cg" errors, since they don't seem to occur anymore (Jendrik Seipp).
• Raise an error if a run command calls a global Python interpreter directly, because this would bypass the virtual environment (Jendrik Seipp).

Downward Lab

• Group rows in unexplained errors table by error message (Jendrik Seipp).

v8.1 (2024-02-28)

Lab

• Allow passing properties files to fetchers directly (Jendrik Seipp).
• Let fetch and report steps log only the total number of unexplained errors instead of printing all of them to stderr (Jendrik Seipp).
• Let parsers print an error if the file for a required pattern is missing. Call parser functions with empty string for missing files (Silvan Sievers).
• Raise an error if a run command calls a Python script directly, because this would bypass the virtual environment (Jendrik Seipp).
• Make HTML table headers sticky (Jendrik Seipp).

Downward Lab
