# X.X.X (Next)

-

# 2.0.0 (2019-09-25)

Security

- Default the `validate_entry_sizes` option to `true`, so that callers can trust an entry's reported size when using `extract` [#403](https://github.com/rubyzip/rubyzip/pull/403)
   - This option defaulted to `false` in 1.3.0 for backward compatibility, but it now defaults to `true`. If you are using an older version of ruby and can't yet upgrade to 2.x, you can still use 1.3.0 and set the option to `true`.

Tooling / Documentation

- Remove test files from the gem to avoid problems with antivirus detections on the test files [#405](https://github.com/rubyzip/rubyzip/pull/405) / [#384](https://github.com/rubyzip/rubyzip/issues/384)
- Drop support for unsupported ruby versions [#406](https://github.com/rubyzip/rubyzip/pull/406)

# 1.3.0 (2019-09-25)

Security

- Add `validate_entry_sizes` option so that callers can trust an entry's reported size when using `extract` [#403](https://github.com/rubyzip/rubyzip/pull/403)
   - This option defaults to `false` for backward compatibility in this release, but you are strongly encouraged to set it to `true`. It will default to `true` in rubyzip 2.0.

New Feature

- Add `add_stored` method to simplify adding entries without compression [#366](https://github.com/rubyzip/rubyzip/pull/366)

Tooling / Documentation

- Add more gem metadata links [#402](https://github.com/rubyzip/rubyzip/pull/402)

- Allow tilde in zip entry names [#391](https://github.com/rubyzip/rubyzip/pull/391) (fixes regression in 1.2.2 from [#376](https://github.com/rubyzip/rubyzip/pull/376))

# 0.9.8

- Fixed: "Unitialized constant NullInputStream" error

# 0.9.5

- Removed support for loading ruby in zip files (ziprequire.rb).

# 0.5.11

- Fixed name clash file method copy_stream from fileutils.rb. Fixed problem with references to constant CHUNK_SIZE.
- ZipInputStream/AbstractInputStream read is now buffered like ruby IO's read method, which means that read and gets etc can be mixed. The unbuffered read method has been renamed to sysread.

# 0.5.10

- Fixed method name resolution problem with FileUtils::copy_stream and IOExtras::copy_stream.

# 0.5.9

- Fixed serious memory consumption issue

# 0.5.8

- Added ZipFile.directory and ZipFile.file - each method return an
  object that can be used like Dir and File only for the contents of the
  zip file.

  Zip::ZipFind.find traverses into zip archives too.
- FIX: AbstractInputStream.each_line with non-default separator

# 0.5.0a

Source reorganized. Added ziprequire, which can be used to load ruby modules from a zip file, in a fashion similar to jar files in Java. Added gtk_ruby_zip, another sample application. Implemented ZipInputStream.lineno and ZipInputStream.rewind

Bug fixes:

- Read and write date and time information correctly for zip entries.

# 0.4.2

- Performance optimizations. Test suite runs in half the time.

# 0.4.1

- Windows compatibility fixes.

# 0.4.0

- Zip::ZipFile is now mutable and provides a more convenient way of modifying zip archives than Zip::ZipOutputStream. Operations for adding, extracting, renaming, replacing and removing entries to zip archives are now available.
- Runs without warnings with -w switch.
- Install script install.rb added.

# 0.3.1

- Rudimentary support for writing zip archives.

# 0.2.2

# 0.1.0

- First working version of ZipInputStream.
