Changes in version 0.4.0.9000                      

                 Changes in version 0.4.0 (2025-12-06)                  

This release updates feather to depend on the arrow package, which is
where Feather format development has moved. This resolves many bug
reports and missing features from the previous implementation of Feather
in R, and it brings the R package in line with the Python feather
package, which has depended on pyarrow since 2017.

For compatibility, feather::write_feather() uses V1 of the Feather
specification: it is a wrapper around arrow::write_feather(version = 1).
Feather V2 is just the Arrow format on disk and has support for a much
richer set of data types. To switch to V2, we recommend just using
arrow::write_feather().

With these changes, most of feather's APIs are preserved in spirit, but
there are some noteworthy changes:

  - The feather class, which allowed for accessing data in a Feather
    file without reading it all into R, has been replaced by an
    arrow::Table backed by the memory-mapped Feather file. This should
    preserve the intent of the original implementation but with much
    richer functionality. One behavior change that results though is
    that slicing/extracting from the Table results in another arrow
    Table, so the data aren't pulled into a data.frame until you
    as.data.frame() them.

  - feather_metadata also now does the same.

                 Changes in version 0.3.5 (2019-09-14)                  

  - Fixes for CRAN

                 Changes in version 0.3.4 (2019-09-03)                  

  - Fixes for CRAN

                 Changes in version 0.3.3 (2019-03-27)                  

  - feather_metadata() now handles paths with ~ in them.

  - Fix warnings on CRAN due to (unused) GNU Makefiles.

  - Use tibble::tibble() in place of the deprecated dplyr::data_frame().

                 Changes in version 0.3.2 (2019-01-07)                  

  - Fixes for PROTECT error found by rchk.

  - Use native routine registration

  - Fix test failure due to UTF-8 encoded paths on Windows.

                 Changes in version 0.3.1 (2016-11-09)                  

Bug fixes and minor features

  - Fixes for gcc-4.4 compilation.

                 Changes in version 0.3.0 (2016-08-25)                  

Underlying feather library changes

  - Feather files are now padded to 64-bit alignment. Feather 0.3 will
    read feather files created by the previous version, but this will
    not be true for future versions of feather.

  - Support for > 2 Gb files on 32-bit windows.

  - Now works with earlier version of C++.

Bug fixes and minor features

  - Automatically close open file handles making it possible to read in
    hundreds of feather files in the same session (@krlmlr, #178)

  - Added a NEWS.md file to track changes to the package.

  - Fixed protection bugs that lead to unpredictable crashes (#150,
    #204).

  - Time fields are now imported as class hms/difftime (#119).

  - Timestamp (POSIXct) fields now correctly restore missing values
    (#157).

  - UTF-8 field names are correctly imported (#198)
