# 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)

# 1.2.4 (2019-09-06)

- Do not rewrite zip files opened with `open_buffer` that have not changed [#360](https://github.com/rubyzip/rubyzip/pull/360)

Tooling / Documentation

- Update `example_recursive.rb` in README [#397](https://github.com/rubyzip/rubyzip/pull/397)
- Hold CI at `trusty` for now, automatically pick the latest ruby patch version, use rbx-4 and hold jruby at 9.1 [#399](https://github.com/rubyzip/rubyzip/pull/399)

# 1.2.3

- 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))
- Support frozen string literals in more files [#390](https://github.com/rubyzip/rubyzip/pull/390)
- Require `pathname` explicitly [#388](https://github.com/rubyzip/rubyzip/pull/388) (fixes regression in 1.2.2 from [#376](https://github.com/rubyzip/rubyzip/pull/376))

Tooling / Documentation:

- CI updates [#392](https://github.com/rubyzip/rubyzip/pull/392), [#394](https://github.com/rubyzip/rubyzip/pull/394)
  - Bump supported ruby versions and add 2.6
  - JRuby failures are no longer ignored (reverts [#375](https://github.com/rubyzip/rubyzip/pull/375) / part of [#371](https://github.com/rubyzip/rubyzip/pull/371))
- Add changelog entry that was missing for last release [#387](https://github.com/rubyzip/rubyzip/pull/387)
- Comment cleanup [#385](https://github.com/rubyzip/rubyzip/pull/385)

# 1.2.2

NB: This release drops support for extracting symlinks, because there was no clear way to support this securely. See https://github.com/rubyzip/rubyzip/pull/376#issue-210954555 for details.

- Fix CVE-2018-1000544 [#376](https://github.com/rubyzip/rubyzip/pull/376) / [#371](https://github.com/rubyzip/rubyzip/pull/371)
- Fix NoMethodError: undefined method `glob' [#363](https://github.com/rubyzip/rubyzip/pull/363)
- Fix handling of stored files (i.e. files not using compression) with general purpose bit 3 set [#358](https://github.com/rubyzip/rubyzip/pull/358)
- Fix `close` on StringIO-backed zip file [#353](https://github.com/rubyzip/rubyzip/pull/353)
- Add `Zip.force_entry_names_encoding` option [#340](https://github.com/rubyzip/rubyzip/pull/340)
- Update rubocop, apply auto-fixes, and fix regressions caused by said auto-fixes [#332](https://github.com/rubyzip/rubyzip/pull/332), [#355](https://github.com/rubyzip/rubyzip/pull/355)
- Save temporary files to temporary directory (rather than current directory) [#325](https://github.com/rubyzip/rubyzip/pull/325)

Tooling / Documentation:

- Several README improvements [#345](https://github.com/rubyzip/rubyzip/pull/345), [#326](https://github.com/rubyzip/rubyzip/pull/326), [#321](https://github.com/rubyzip/rubyzip/pull/321)

- Added read-only support for Zip64 files.
- Added support for setting Unicode file names.

# 0.9.9

# 0.9.8

- Fixed: "Unitialized constant NullInputStream" error

# 0.9.5

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

# 0.9.4

- Changed ZipOutputStream.put_next_entry signature (API CHANGE!). Now allows comment, extra field and compression method to be specified.

# 0.9.3

- Fixed: Added ZipEntry::name_encoding which retrieves the character encoding of the name and comment of the entry.
- Added convenience methods ZipEntry::name_in(enc) and ZipEntry::comment_in(enc) for getting zip entry names and comments in a specified character encoding.

# 0.9.2

- Fixed: Renaming an entry failed if the entry's new name was a different length than its old name. (Diego Barros)

# 0.9.1

- Added symlink support and support for unix file permissions. Reduced memory usage during decompression.
- New methods ZipFile::[follow_symlinks, restore_times, restore_permissions, restore_ownership].
- New methods ZipEntry::unix_perms, ZipInputStream::eof?.

# 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

- Fixed install script.

# 0.5.7

- install.rb no longer assumes it is being run from the toplevel source dir. Directory structure changed to reflect common ruby library project structure. Migrated from RubyUnit to Test::Unit format. Now uses Rake to build source packages and gems and run unit tests.

# 0.5.6

# 0.5.4

- Significantly reduced memory footprint when modifying zip files.

- Changed method names from camelCase to rubys underscore style.
- Installs to zip/ subdir instead of directly to site_ruby
- 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.
- Added sample application zipfind which works like Find.find, only
  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.
- Fixed read() using separate buffer, causing mix of gets/readline/read to cause problems.

# 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

- Fixed and extended unit test suite. Updated to work with ruby/zlib 0.5. It doesn't work with earlier versions of ruby/zlib.

# 0.2.0

- Class ZipFile added. Where ZipInputStream is used to read the individual entries in a zip file, ZipFile reads the central directory in the zip archive, so you can get to any entry in the zip archive without having to skipping through all the preceeding entries.

# 0.1.0

- First working version of ZipInputStream.
