## 0.3.0 - 2017-01-25

### Added

* TrueType font subsetting support
* Image extraction ability to CLI via `hexapdf images` command
* [HexaPDF::Type::Image#write] for writing an image XObject to an IO stream or
  file
* [HexaPDF::Type::Image#info] for getting image properties of an image XObject
* CLI option `--[no-]force` to force overwriting existing files

### Changed

* Refactor `hexapdf modify` command into three individual commands `modify`,
  `merge` and `optimize`
* Rename `hexapdf extract` to `hexapdf files` and the option `--indices` to
  `--extract`
* Show PDF trailer by default with `hexapdf inspect`
* Refactor CLI command classes to use specialized superclass
  [HexaPDF::CLI::Command]
* Optimize parsing of PDF files for better performance and memory efficiency

### Fixed

* Writing of hybrid-reference PDF files - they are written as standard PDF files
  since all current applications should be able to handle PDF 1.5
* Serialization of self-referential, indirect PDF objects
* Performance problem for `hexapdf inspect --pages` when inspecting huge files
* TrueType compound glyph component offset calculation
* Parsing of TrueType data type 'fixed'
* Updating a PDF trailer's ID field when it isn't an array

## 0.2.0 - 2016-11-28

### Added

* PDF file merge ability to `hexapdf modify`, i.e. adding pages from other PDFs

* Validation for [HexaPDF::Rectangle] objects
* [HexaPDF::Font::Type1::FontMetrics#weight_class] for returning the numeric
  weight

### Changed

* Refactor document utilities into own classes with a more Ruby-like interface;
  concern fonts, images and files, now accessible through
  [HexaPDF::Document#fonts], [HexaPDF::Document#images] and
  [HexaPDF::Document#files]
* Validate nested collection values in [HexaPDF::Object]
* Allow [HexaPDF::Dictionary#[]] to always unwrap nil values
* Update [HexaPDF::Task::Optimize] to delete unused objects on `:compact`
