0.133.1

Highlights

1

This release doubles down on Polars' capabilities, as we now, as a matter of policy track the latest polars upstream. If you think qsv has a torrid release schedule, you should see Polars. They're constantly fixing bugs, adding new features and optimizations! To keep up, we've added Polars revision info to the --version output, and the --envlist option now includes Polars relevant env vars. We've also added support for the POLARS_BACKTRACE_IN_ERR env var to control whether Polars backtraces are included in error messages. We also removed the to parquet subcommand as its redundant with the Polars-powered sqlp's ability to create parquet files. This removes the HUGE duckdb dependency, which should markedly make compile times shorter and binaries smaller.

Other highlights include:

• New edit command that allows you to edit CSV files.
• The count command's --width option now includes record width stats beyond max length (avg, median, min, variance, stddev & MAD).
• The fixlengths command now has --quote and --escape options.
• The stats command adds a sort_order streaming statistic.

NOTE: 0.133.0 was skipped because of a dev dependency conflict with the csvs_convert crate, preventing us from publishing 0.133.0 to crates.io. This has been resolved in 0.133.1.
