Improvements:
- Increased CHUNK size as per miniz instructions
- Added tests for very large arrays in NPZ files
- Added some CI tests to catch issues across platforms
- Removed the internal IO streams in favor of just using stringstream
- NPZs can now be read from and written to memory
Bugfixes:
- Fixed an issue where very large arrays in NPZ files would throw an error
- Fixed a bug with mac builds due to deprecated APIs
Removing using namespace std to simplify library use
Improvements:
- CMake build now uses the highest compiler warning/error setting
Bugfixes:
- Fixed some bugs exposed by heightened compiler warnings
Improvements:
- Added a
keysmember toinpzstreamso it is possible to query the keys of the tensors
Bug fixes:
- Fixed a bug with integer shifting
Improvements:
- Further minor CMake changes to improve ease of use
- NPZ streams now have
is_openmethods to check for successful file opening - Minor code style changes
Bug fixes:
- NPZ files will now correctly handle PKZIP versions after 2.0, both for reading and writing
Improvements:
- Updated CMake integration to make the library easier to use via
FetchContent
New Features:
- Support for Unicode string tensors (npy type 'U')
Breaking change:
CopyFrominterface for C# Tensors has been changed to use *Buffer objects
Improvements:
- Bug fix for a missing comma on 1d shape
Improvements:
- Bug fix for scalar tensor reading
- Bug fix with memstream buffer size at initialization
- ".npy" will be added to tensor names in NPZ writing if not already present
New Features:
- Easier indexing (variable argument index method + negative indexes)
- Easier access to shape
Improvements:
- Cmake upgraded to "modern" usage, i.e. you use the library by adding
npy::npyas a link library
Improvements:
- Minor cmake change
New Features:
- Zip64 compatibility
Improvements:
- Can use
numpystyle lookup for tensors (i.e. dropping the.npyfrom the name) - Added a crc32 test
New Features:
- There is no longer a dependency on
zlib
Improvements:
- Better packaging (NuGet packages are now produced for C++ and C#)
Breaking changes:
- Renamed
endian=>endian_t - Renamed
data_type=>data_type_t - Renamed
compression_method=>compression_method_t
New Features:
- Cleaned up exception handling. There are now tests for exceptions being correctly thrown, and the exceptions are properly wrapped for .NET-
- Added peeking for NPY files to get the header information, and contains/peek functionality for
inpzstream.
Improvements:
- Removed the unnecessary copies in the compression/decompression process
