zipstream-ng changelog
======================

### [v1.9.0]
- Add support for Zstandard compression where available (Python 3.14+)

### [v1.8.0]
- Support adding directory contents at the top level of the `ZipStream` by specifying an arcname of `/`
- Fix issue where leading path separators could cause an incorrect size to be calculated.

### [v1.7.1]
- Fix issue where it was possible to add paths with arcnames that didn't match the path contents
  (file ending with "/", directory not ending with "/")

### [v1.7.0]
- Add the ability to get information on added files using `ZipStream.info_list`. This function
  replaces `ZipStream.get_info` which would only provide information on files that had already been
  streamed.
- Deprecate `ZipStream.get_info`. It will continue to work until the next major version but
  will now emit a warning when used.
- Reduce memory usage for sized `ZipStream` objects by updating the final size of the stream as
  files are added instead of storing the required information so the size could be calculated later.

### [v1.6.0]
- Add the ability to provide a custom "walk" function to `ZipStream.add_path` for more control
  over how directories are walked.
- Change the exception raised when trying to add a file that doesn't exist from a `ValueError` to a
  more appropriate `FileNotFoundError`.
- Optimize the number of `os.stat` calls required to add a file.
- Fix issue where adding data with an arcname that contained a null byte would lead to an incorrect
  size being calculated.
- When `ZipStream.add` is provided a size alongside an iterable, the size will now be used to
  determine if Zip64 extensions are needed.

### [v1.5.0]
- Add `ZipStream.mkdir` method to make an empty directory inside the stream.
- Fix an issue where `ZipStream.get_info` would return incorrect values for `compress_level` in
  cases where the compression level was specified, but had no effect (ie. when using
  `ZIP_STORED`/`ZIP_LZMA`).
- Fix an edge case where top-level paths like `/` could be added with an empty arcname.
- Improve error messages for adding data as a directory and adding nonexistent paths.

### [v1.4.0]
- The expected size of data added to a `ZipStream` is now validated as it's generated. For unsized
  `ZipStream`s a mismatch in expected vs. actual size emits a warning, for sized `ZipStream`s a
  `RuntimeError` is raised.
- For sized `ZipStream`s, add the option to provide the total size of an iterable when adding it.
  When the size is provided, the iterable will no longer have to immediately be read into memory to
  compute it.

### [v1.3.5]
- Fix issue where adding data via an iterable to an unsized `ZipStream` wouldn't fully implement
  Zip64 extensions. This caused some versions of `7z` to emit warnings (but still properly extract
  the data).

### [v1.3.4]
- Fix issue where adding files with multibyte characters in the filename would lead to an incorrect
  zip size being calculated.

### [v1.3.3]
- Fix issue where directly adding an empty folder would give it the wrong name in the archive and
  lead to an incorrect zip size being calculated.

### [v1.3.2]
- Fix documentation issue caused by the import shuffling in v1.3.1
- Set external attributes (permissions, directory flag, etc) on data added to the `ZipStream` via `add()`

### [v1.3.1]
- Allow importing functionality from `zipstream.ng` as well as `zipstream` to avoid namespace
  collisions with other projects that provide a `zipstream` module.

### [v1.3.0]
- Add a `last_modified` property to `ZipStream` objects that returns a `datetime` of the most recent
  modified date of all the files in the stream.

### [v1.2.1]
- Fix issue where adding empty directories would lead to an incorrect zip size being calculated.
- Fix issue where asking for the `ZipStream`'s size multiple times while adding data wouldn't
  properly check if Zip64 extensions were being used, causing an incorrect size to be calculated.

### [v1.2.0]
- Add a `sized` property to `ZipStream` objects that checks if the size can be calculated for it
- Change `ZipStream.from_path` to generate a sized `ZipStream` if no compression is used

### [v1.1.0]
- Add support for Python 3.5 and 3.6
