v1.2.0 (2023-12-11)#

  • #124: Added support for chunking FASTA reads to read_paired_chunks. Previously, only FASTQ was supported.

v1.1.0 (2023-11-20)#

  • #116: Added experimental support for reading unaligned BAM files (single-end only at the moment). This uses a custom, highly efficient BAM parser, making dnaio faster than htslib in this particular case.

v1.0.1 (2023-10-06)#

  • #120: Improved type annotations.

  • Dropped support for Python 3.7

  • Added support for Python 3.12

v1.0.0 (2023-09-06)#

  • #110: Added id and comment properties to SequenceRecord.

v0.10.0 (2022-12-05)#

  • #99: SequenceRecord initialization is now faster, which also provides a speed boost to FASTQ iteration. SequenceRecord.__new__ cannot be used anymore to initialize SequenceRecord objects.

  • #96: open_threads and compression_level are now added to open as arguments. By default dnaio now uses compression level 1 and does not utilize external programs to speed up gzip (de)compression.

  • #87: open can now open more than two files. The file1 and file2 arguments are now deprecated.

v0.9.1 (2022-08-01)#

  • #85: macOS wheels are now also built as part of the release procedure.

  • #81: API documentation improvements and minor code refactors for readability.

v0.9.0 (2022-05-17)#

  • #79: Added a records_are_mates function to be used for checking whether three or more records are mates of each other (by checking the ID).

  • #74, #68: Made FASTQ parsing faster by implementing the check for ASCII using SSE vector instructions.

  • #72: Added a tutorial.

v0.8.0 (2022-03-26)#

  • Preliminary documentation is available at <>.

  • #53: Renamed Sequence to SequenceRecord. The previous name is still available as an alias so that existing code will continue to work.

  • When reading a FASTQ file, there is now a check that ensures that all characters are ASCII.

  • Function record_names_match is deprecated, use is_mate instead.

  • Added reverse_complement.

  • Dropped Python 3.6 support as it is end-of-life.

v0.7.1 (2022-01-26)#

  • #34: Fix parsing of FASTA files that just contain a comment and no reads

v0.7.0 (2022-01-17)#

  • @rhpvorderman contributed many performance improvements in #15, #17, #18, #20, #21, #22, #23. Reading and writing FASTQ files and reading of paired-end FASTQ files was sped up significantly. For example, reading uncompressed FASTQ is 50% faster (!) than before.

  • #28: Windows support added

v0.6.0 (2021-09-28)#

  • #12: Improve FASTQ writing speed twofold (thanks to @rhpvorderman)

v0.5.2 (2021-09-07)#

  • #7: Ignore a trailing “3” in the read id
