Pre-Release 3.0.0a2

• Removed Parser2 and related infrastructure. It was already replaced by Parser in
  previous release, but I didn't have time to make sure all of dependencies were gone.
• Removed most of the old documentation.
• Moved pygerber.gerberx3 to pygerber.gerber. I acknowledge this is a breaking
  change, but using gerberx3 as a package name when it in fact contained code mostly
  compatible with more than just X3 was misleading.
• Moved pygerber.gerber.ast.builder to pygerber.builder.gerber.
• Moved pygerber.vm.builder to pygerber.builder.rvmc.
• Added new documentation layout.
• Added documentation for GerberX3Builder from pygerber.builder.gerber module.
• Added Quick start guide to documentation.
• Added pygerber.gerber.pygments, a Pygments lexer for Gerber files. To use it you
  have to install pygments extras package (or just have pygments installed from other
  source).
• Added support for deprecated syntax construct of D01 with code omitted.
• Changed pygerber.gerber.formatter API and structure. Formatter options are no longer
  directly passed to Formatter class, they are stored in dedicated Options class.
• Added 2 high level formatter API functions available in pygerber.gerber.formatter:
  format, formats.
• Improved docstrings in pygerber.builder.gerber
• Improved pygerber.gerber.formatter docstrings, especially ones related to formatter
  options.
• Changed pygerber.gerber.api to use pygerber.builder.gerber. This is a major change
  in how this API works. I am planning to create some guide on how to migrate code from
  PyGerber 2.4.x to 3.x.x, there is placeholder docs page for that.
• Deleted implementation of command line interface. Unfortunately, command line
  interface is not functional right now.

Pre-Release 3.0.0a0

• Added pygerber.gerberx3.formatter for formatting Gerber files.
• Added GerberX3Builder class for building Gerber code from scratch.
• Redesigned PyGerber Parser implementation and AST classes.
• Added intermediate step between parsing and rendering done by
  pygerber.gerberx3.compiler.
• Redesigned rendering principles, now implemented in pygerber.vm, supports only
  rendering raster images with Pillow. SVG rendering is planned to be included in 3.0.0
  release.
• Ported language server to new parser.

Release 2.4.1

• Added support for comment based attributes (#217)
• Fixed incorrect rotation of rectangle flashes (#243)
• Removed PyYAML dependency (#221)
• Added tests for language server (#227)
• Added tests for console interface (#223)

Release 2.4.0

• Added command line interface utilizing API V2 for rendering Gerber files to images.
  This includes interface for rendering PNG, JPEG and SVG images and multi-file projects
  to single PNG/JPEG image.
• Added support for inferring file type from file extension or .FileFunction file
  attribute. This mechanism is used by default by API V2 based command line interface.
• Refactored test suite and dropped testing of code related to Parser class originally
  included in PyGerber 2.0.0. Currently only Parser2 related code is actively
  tested.

Release 2.3.2

• Fixed clockwise arc rendering in raster renderer. Reported by @tgbl-mk (#203). Fixed
  by @Argmaster in #205.
• Fixed empty comment parsing. Reported by @lookme2 (#198). Fixed by @Argmaster in #201.
• Disabled MacOS test suite due to consistent failures during Python installation on
  macos-latest GitHub hosted machines.

Release 2.3.1

• Added support for rotation of code 21 center line macro primitive in SVG and Raster
  renderers. Support is not exhaustive, it will be extended whenever extension is
  requested by users.
• Fixed bug causing macro flashes to be partially cut off in images rendered with SVG
  renderer.
• Fixed incorrect version string in pygerber.__version__ and reported by
  pygerber --version.

Release 2.3.0

• Added full support for transforms (LP, LM, LR, LS commands) in Parser2.
• Fixed titles in Parser2 and Parser feature support documentation. They were swapped.
• Fixed bug causing SvgRenderer2 to incorrectly render masks in some cases.
• Optimized SvgRenderer2 group and mask usage to reduce file size and memory usage of
  software displaying output SVGs.
• Fixed parsing of attributes without value.
• Updated documentation to mention deprecation of API V1 elements and changed order of
  pages to better expose API V2.
• Added example files shipped with PyGerber for testing and demonstration purposes. They
  can be accessed via pygerber.examples module.
• Added new pygerber.gerberx3.api.v2 module with new high level utilizing API V2
  capabilities. This module is mend to replace API V1 in future releases.
• Added new API for rendering multiple Gerber files at once into single image. Available
  as part of pygerber.gerberx3.api.v2 module with use of Project class.
