* Add support for `use` statement groups.

* Don't throw fatal errors when conditionally redefining classes and functions.
* Fix `parse` command for older PHP Parser versions.
* Add `bin/package`, to hopefully make our automatic releases go a bit smoother.

Our biggest release notes yet!

New:

* Add a Hoa\Console-based pure PHP readline fallback, for PHP installs compiled without readline or libedit (Thanks @zonuexe)
* Automatically check for updates (Thanks @eeree!)
* Add an `updateCheck` frequency configuration. It defaults to `weekly`, but you can set it to `always`, `daily`, `weekly`, `monthly` or `never`.
* Update to PHP Parser v3.0, with better PHP 7.1 support (Thanks @GrahamCampbell!)
* Add support for language constructs (`isset`, `unset`, `empty`, etc) in the `doc` command.
* Build a `psysh-compat` as well as `psysh` Phar. The second Phar contains polyfills for intl and readline. It's quite a bit bigger, but also quite a bit more useful for PHP installs without all the bells and whistles.

Improved:

* Fix "uninitialized string offset" in autocomplete matchers.
* Prevent PHP's built-in webserver from hanging after debugging (Thanks @5tevan!)
* Allow recursive static calls when defining classes.
* Shrink compiled Phar size by ~10%.
* Fix VarDumper truncating null bytes in output.
* Add support for multiline comment input.
* Catch invalid pass by reference arguments.
* Better handling for Error in newer PHPs.
* Better formatting for error output.
* Build Phar with `detect_unicode=Off` if compiled under PHP 5.3, because PHP 5.3.
* Various fixes for HHVM tests.

And a couple of things I'm prolly more excited about than you:

* Test the lowest versions of all dependencies in CI. They're all currently failing, but it's a start :)
* Speed up CI builds by disabling xcode.
* Build GitHub releases on CI for great justice.

 * Fix class not found exception when defining a class which refers t…

…o itself.

 * Fix a regression when defining custom commands.
 * Add support for `declare(strict_types=1)`.

 * A few tweaks to play nicer with HHVM.

 * Fix a bug with self::, parent:: and static:: calls.
 * Fix incorrectly suppressed `echo '0'` output.

 * More correct "return value" for things like use statements.

 * Initialize tab completion later, so that added commands get completion (Thanks @damiankloip!)
 * Add a CodeCleaner pass to make `exit;` act like the `exit` command (Thanks @damiankloip!)
 * Don't assume the presence of `argv` in `$_SERVER`.
 * Add color mode overrides, via `colorMode` configuration and `--color` or `--no-color` flags (Thanks @toddmazierski!)
 * Add a `useUnicode` config option. Set this to false to avoid non-ascii characters in PsySH output, for example if you're on Windows and don't want to fight with code page configuration.
 * Update README, documentation, etc (Thanks @dereckson and @ReadmeCritic!)

 * Fix Windows config directory logic bug (Thanks @mix5003!)

 * Support for PHP Parser v2.0, with better PHP 7 support (Thanks @al…

…exeyshockov, et al!)

 * Add `errorLoggingLevel` and `warnOnMultipleConfigs` configuration options.
 * Support for local config files (Thanks @shadowhand!)
 * Compatibility with Symfony v3.0 (Thanks @nicolas-grekas!)
 * Configuration path cleanup, bugfixes, etc. Windows users, things are much more robust for you now.
 * Change a bunch of old deprecation warnings to exceptions.
 * Fix all but one HHVM test failure!
 * Fix for `class` magic constants (Thanks @lvht!)
 * Stop throwing errors on interface contstants.
 * Improved phar build process and dependency compilation.
 * Tons of CS fixes. And some CS fixer configuration fixes (Thanks @GrahamCampbell!)

* Fix recursion in ValidFunctionNamePass.

 * Fix php-parser dependency version.

New:

 * Support PHP 7 (Thanks @GrahamCampbell, etc!)
 * Switch to VarDumper for `dump` and return values (Thanks @nicolas-grekas!)
 * Add framework and project integrations to the README.
 * Add `\Psy\info()` function for help filing and debugging issues.
 * Add a bin launcher so that global and local PsySH installs Just Work (See bobthecow#172)

Improved:

 * Update to latest dependency versions.
 * Update minimum PHP version to 5.3.9 (required by VarDumper).
 * Improved error messages, dependency installation prompts.
 * Config fixes for newest php-cs-fixer and StyleCI, various CS fixes (Thanks @GrahamCampbell!)
 * Fix a bug when trying to continue unclosed single quoted strings on a new line.
