+ * added `CommandLoaderInterface`, `FactoryCommandLoader` and PSR-11
+   `ContainerCommandLoader` for commands lazy-loading
+ * added a case-insensitive command name matching fallback
+ * added static `Command::$defaultName/getDefaultName()`, allowing for
+   commands to be registered at compile time in the application command loader.
+   Setting the `$defaultName` property avoids the need for filling the `command`
+   attribute on the `console.command` tag when using `AddConsoleCommandPass`.
+
+3.3.0
+-----
+
+* added `ExceptionListener`
+* added `AddConsoleCommandPass` (originally in FrameworkBundle)
+* [BC BREAK] `Input::getOption()` no longer returns the default value for options
+  with value optional explicitly passed empty
+* added console.error event to catch exceptions thrown by other listeners
+* deprecated console.exception event in favor of console.error
+* added ability to handle `CommandNotFoundException` through the 
+ `console.error` event
+* deprecated default validation in `SymfonyQuestionHelper::ask`
+
+3.2.0
+------
+
+* added `setInputs()` method to CommandTester for ease testing of commands expecting inputs
+* added `setStream()` and `getStream()` methods to Input (implement StreamableInputInterface)
+* added StreamableInputInterface
+* added LockableTrait
+
+3.1.0
+-----
+
+ * added truncate method to FormatterHelper
+ * added setColumnWidth(s) method to Table 
+
+2.8.3
+-----
+
+ * remove readline support from the question helper as it caused issues
+
+2.8.0
+-----
+
+ * use readline for user input in the question helper when available to allow
+   the use of arrow keys
+
+2.6.0
+-----
+
+ * added a Process helper
+ * added a DebugFormatter helper
+
+2.5.0
+-----
+
+ * deprecated the dialog helper (use the question helper instead)
+ * deprecated TableHelper in favor of Table
+ * deprecated ProgressHelper in favor of ProgressBar
+ * added ConsoleLogger
+ * added a question helper
+ * added a way to set the process name of a command
+ * added a way to set a default command instead of `ListCommand`
+
+2.4.0
+-----
+
+ * added a way to force terminal dimensions
+ * added a convenient method to detect verbosity level
+ * [BC BREAK] made descriptors use output instead of returning a string
+
+2.3.0
+-----
+
+ * added multiselect support to the select dialog helper
+ * added Table Helper for tabular data rendering
+ * added support for events in `Application`
+ * added a way to normalize EOLs in `ApplicationTester::getDisplay()` and `CommandTester::getDisplay()`
+ * added a way to set the progress bar progress via the `setCurrent` method
+ * added support for multiple InputOption shortcuts, written as `'-a|-b|-c'`
+ * added two additional verbosity levels, VERBOSITY_VERY_VERBOSE and VERBOSITY_DEBUG
+
+2.2.0
+-----
+
+ * added support for colorization on Windows via ConEmu
+ * add a method to Dialog Helper to ask for a question and hide the response
+ * added support for interactive selections in console (DialogHelper::select())
+ * added support for autocompletion as you type in Dialog Helper
+
+2.1.0
+-----
+
+ * added ConsoleOutputInterface
+ * added the possibility to disable a command (Command::isEnabled())
+ * added suggestions when a command does not exist
+ * added a --raw option to the list command
+ * added support for STDERR in the console output class (errors are now sent
+   to STDERR)
+ * made the defaults (helper set, commands, input definition) in Application
+   more easily customizable
+ * added support for the shell even if readline is not available
+ * added support for process isolation in Symfony shell via
+   `--process-isolation` switch
+ * added support for `--`, which disables options parsing after that point
+   (tokens will be parsed as arguments)
