Release 0.89.0 · jqnatividad/qsv

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

--version now returns "non-streaming" mode max input file size and detailed memory info. See Version details for more info #780
exclude: expanded usage text and added 'input parameters' help by @tmtmtmtm in #783
stats: performance tweaks in 96e8168, 634d42a and 7e148cf
Use simdutf8 to do SIMD accelerated utf8 validation, replacing problematic utf8 screening. Together with #782, completes utf8 validation revamp. #784
Bump sysinfo from 0.27.7 to 0.28.0 by @dependabot in #786
cargo update bump several indirect dependencies
pin Rust nightly to 2023-02-18

Removed patched versions of csv crate optimized for performance. With the release of csv 1.2, switched back to csv crate upstream. #794
removed utf8 first 8k screening. It was increasing code complexity and not very reliable. #782

dedup: refactored to use iterators to avoid out of bounds errors. f5e547b
exclude: don't screen for utf8. This bugfix spurred the utf8 validation revamp, where I realized, I just needed to pull out utf8 screening #781
py: col, not row #793
