Full Changelog: 0.89.0...0.90.0

0.89.0

Added

• cat: added new rowskey subcommand. Unlike the existing rows subcommand, it allows far more flexible concatenation of CSV files by row, even if the files have different number of columns and column order. #795
• added jemalloc support. As the current default mimalloc allocator is not supported in some platforms. Also, for certain workloads, jemalloc may be faster. See Memory Allocator for more info #796
• added --no-memcheck and related QSV_NO_MEMORY_CHECK env var. This relaxes the conservative Out-of-Memory prevention heuristic of qsv. See Memory Management for more info #792

Changed

Fixed

• dedup: refactored to use iterators to avoid out of bounds errors. f5e547b

• py: col, not row #793

New Contributors

• @tmtmtmtm made their first contribution in #783

Full Changelog: 0.88.2...0.89.0
