New cli_env configuration was added for setting extra environment variables for every CLI command:

MiniMagick.configure do |config|
  config.cli_env = { "MAGICK_MEMORY_LIMIT" => "128MiB" }
end

New graphicsmagick configuration was added for telling MiniMagick to use GraphicsMagick instead of MiniMagick:
```
MiniMagick.configure do |config|
  config.graphicsmagick = true # prepend all commands with "gm"
end
```
Previously, the recommended approach was setting MiniMagick.cli_prefix = "gm", but that doesn't work when ImageMagick 7 is installed, as in that case MiniMagick will try to prepend magick on top of gm.

MiniMagick::Image#write doesn't delete the internal tempfile anymore, which restores use cases like:

image = MiniMagick::Image.open("...")
image.resize("500x500")
image.write("foo.jpg")
image.blur
image.write("bar.png")

Prevented MiniMagick::Image#to_ary being called by ruby in certain cases, such as [image].flatten(1).

Improvements

New class method shorthands were added for the tool API:

# BEFORE
MiniMagick::Tool::Convert.new { |convert| ... }
MiniMagick::Tool::Identify.new { |convert| ... }
# ...

# AFTER
MiniMagick.convert { |convert| ... }
MiniMagick.identify { |identify| ... }
# ...

Image#write now deletes the underlying tempfile if Image.open was used, instead of relying on the tempfile to eventually be garbage collected.

Backwards compatibility

Removed official GraphicsMagick support. GraphicsMagick can be used by setting cli_prefix:
```
MiniMagick.configure do |config|
  config.cli_prefix = "gm"
end
```
Some features won't be supported, such as MiniMagick.timeout (GraphicsMagick doesn't support time limits), Image#data (GraphicsMagick doesn't support JSON image details) and Image#exif (returns different format).

As a result, MiniMagick.cli and MiniMagick.processor configuration has been removed as well.
MiniMagick::Image and MiniMagick.convert now use magick instead of the deprecated magick convert on ImageMagick 7. This should be backwards compatible, but there might be small differences in options and behavior.
Removed deprecated posix-spawn shell backend, along with MiniMagick.shell_api configuration.

Ruby 2.x has long used vfork, so there is no performance advantage of using posix-spawn. Additionally, Ruby 3.x has switched to non-blocking pipes, which should resolve deadlocks people experienced with Open3. See https://github.com/minimagick/minimagick/pull/558 for more details.
Removed obsolete Image#run_command.
Removed deprecated Image#mime_type, as it wasn't accurate.

MIME type from file content should be determined either using Marcel or MimeMagic, or mime-types or MiniMime using Image#type.
The MiniMagick::Tool::* classes have been deprecated in favor of the class-level interface.
The MiniMagick.timeout configuration now uses the native ImageMagick timeout environment variable $MAGICK_TIME_LIMIT. This variable doesn't support timeouts lower than 1 second.
The MiniMagick.whiny configuration has been renamed to MiniMagick.errors.
Images are no longer automatically validated on Image.open, Image.read or Image.create.
The deprecated Image#details method has been removed in favor of the more reliable Image#data.
The Image#respond_to_missing? method has been removed, meaning that Image#respond_to? will return false for ImageMagick option methods.

As a result, the undocumented MiniMagick::Tool.option_methods method has been removed as well, along with the no-op MiniMagick.reload_tools.
Removed the obsolete MiniMagick.processor_path configuration, which as mostly an alias for MiniMagick.cli_path.
Removed the deprecated MiniMagick.debug configuration in favor of MiniMagick.logger.level = Logger::DEBUG.
Removed the unused MiniMagick.validate_on_write configuration.
Additional Pathname#open or URI#open options for Image.open need to be passed in as keyword arguments instead of a hash.

Warnings about convert command being deprecated on ImageMagick 7 are now ignored.

The next major version of MiniMagick will switch to using magick on IM7, as it might not be fully compatible with magick convert.
If processing images is returning warnings (e.g. TIFF images tend to do that), but they're otherwise fine, you can prevent MiniMagick from forwarding warnings to standard error:
```
MiniMagick.configure do |config|
  config.warnings = false
end
```
When the ImageMagick subprocess has been abruptly killed by the operating system (e.g. OOM kill), in which case the exit status will be unknown, MiniMagick will now handle this gracefully.
When validating the image, the cheap info will now be automatically stored on the MiniMagick::Image object, so a subsequent call to #type, #width, #height, #dimensions, #size or #human_size will not call identify again.
The posix-spawn shell backend has been deprecated (see https://github.com/minimagick/minimagick/pull/558).

Ruby uses vfork since Ruby 2.2, so posix-spawn doesn't provide performance benefits on relevant Ruby versions anymore. Additionally, Ruby 3 switched to non-blocking pipes by default, which should hopefully resolve deadlocks with open3 (see https://github.com/minimagick/minimagick/issues/347 and https://github.com/minimagick/minimagick/pull/437). Due to this change, posix-spawn is currently incompatible with Ruby 3.
MiniMagick::Image#mime_type has been deprecated, due to returning incorrect MIME type for formats not starting with image/*.

ImageMagick does have a way to return the MIME type, but it requires reading the whole image, which is significantly slower. It's recommended to use Marcel or MimeMagic for determining MIME type from magic header. Alternatively, you can use mime-types or MiniMime for obtaining MIME type from file extension or from MiniMagick::Image#type.
Ruby 2.3+ is now required.

New features

Support ImageMagick 7
- MiniMagick::Tool::Convert will now generate magick convert commands (and the same for others)
- MiniMagick::Tool::Magick was added for generating magick commands

MiniMagick.cli_prefix was added to configure a prefix for commands

MiniMagick.cli_prefix = "firejail"

MiniMagick::Tool::Magick.new { |magick| ... } # executes `firejail magick ...`

Other Improvements

Fix deadlocks when using posix-spawn as a shell backend
Fix Errno::ESRCH sometimes being raised when the ImageMagick command would time out

#label and #caption will now generate regular options

  convert.label("foo")   # label:foo    -label foo

Added MiniMagick::Image#get_pixels, which returns a matrix where each member is a 3-element array of numbers between 0 and 255, one for each of the RGB channels.
When MiniMagick.timeout is set and the command times out, previously the command would still continue running in the background. Now when Timeout::Error is raised, we also kill the subprocess running the command with SIGTERM.
Implementation of posix-spawn has been improved, where now both stdout and stderr are read from at the same time, stdin pipe is closed immediately after writing the input, and stdout and stderr pipes are closed once the command finishes. This now has essentially the same behaivour as Open3.popen3 with a block.

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
