v4.6.0

• Fix Image#exif raising an error when an exif value contains a "=" chracter
• Fix Image#exif raising an error when an exif value spans on multiple lines
• Introduced Image#data as an alternative to Image#details, which uses ImageMagick's ability to retrieve identify -verbose output in JSON format. This eliminates possibility of any parsing errors. It is available on ImageMagick 6.8.8-3 or above.
• Allow Image#format to accept a hash of options as a third argument, which will be added to the convert command before original path is added
• Support Pathname in Image.new, as we already supported Pathname in Image.open
• Added Tool#stdout which adds - to the command (the same as Tool#stdin does)

v4.5.1

• Fixed MiniMagick logging commands by default

v4.5.0

New features

• Added the ability for ImageMagick commands to accept standard input:

  identify = MiniMagick::Tool::Identify.new
  identify.stdin # adds "-"
  identify.call(stdin: image_content)

• Added ability to capture stdout, stderr and exist status by passing a block to MiniMagick::Tool#call:

  compare = MiniMagick::Tool::Compare.new
  # build the command
  compare.call do |stdout, stderr, status|
    # ...
  end

• Added ability to assign MiniMagick.logger to Rails.logger

Bug fixes

• The value of MiniMagick.whiny configuration option is now respected
• The new filename when calling #format is now generated better when calling on a layer
• Delete *.cache files generated by .mpc files when deleting MiniMagick::Image

Deprecations

• Whiny option should now be passed as a keyword argument:

  MiniMagick::Tool::Identify.new(false) # deprecated
  MiniMagick::Tool::Identify.new(whiny: false) # good

• Passing the whiny argument to MiniMagick::Tool#call is deprecated, it should now always be passed to MiniMagick::Tool.new

v4.4.0

• Using MiniMagick::Image#format now works when the image instance is a layer/frame/page.
• Calling MiniMagick::Tool#clone as a way of adding the -clone CLI option now works properly (before it would call Object#clone).
• Badly encoded lines in identify -verbose don't cause an error anymore in MiniMagick::Image#details.
• MiniMagick::Image#details doesn't hang anymore when clipping paths are present
• Added MiniMagick::Image#tempfile for accessing the underlying temporary file.

v4.3.6

• Restore the old behaviour of MiniMagick::Image#respond_to? by looking at mogrify -help and finding the method. This restores compatibilty with CarrierWave.

v4.3.5

• mini_magick/version.rb is now properly required in the main file (previously MiniMagick.version was throwing a NoMethodError unless you explicitly required mini_magick/version.rb)

v4.3.4

• Fix MiniMagick::Tool#tile method being applied as a creation operator (tile:) instead of an option (-tile)

v4.3.3

• Fixed a bug where, if you would reference any image info inside Image#format {} or Image#combine_options {}, this info would be cached even after these methods were executed, leaving the MiniMagick::Image instance with stale data.

v4.3.2

• Fixed MiniMagick::Image.new("...").format("<ext>") not working if the image didn't have an extension.

v4.3.1

• Reverted making MiniMagick configuration thread safe, until we figure out what caused #328.
