PsySH v0.8.2

New:

• Add a startupMessage config option (Thanks @gitetsu!)
• Reflecting commands (dump, ls, show, doc) now add magic variables so you can do fun things with them: $__class, $__file, $__method, etc.

Improved:

• Fix some mistyped annotations and add a phan config (Thanks @zonuexe!)
• Handle file permissions errors for update checks and history files more gracefully (Thanks @zonuexe!)
• Handle PHP 7.x \Errors thrown while serializing the shell return value (Thanks @damiankloip!)
• Deal with variables named $this (like if you started your shell session from inside a class method) without exploding in PHP 7.1+.
• Improve the accuracy of info returned by Psy\info().
• Fix an error preventing Psy\info() from doing anything at all in the last release :-(
• Don't let local configuration interfere with config unit tests.
• Make reflecting commands superglobals-aware. dump is the only one that actually does anything useful with a superglobal, but now the others have reasonable output.
• Fix fatal error when trying to extend final classes.
• Make a few things reference static instead of self to make extension easier (Thanks @castarco!)
• Fix a handful of bugs around escaping special characters (and <) while dumping values.

PsySH v0.8.1

• 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.

PsySH v0.8.0

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 xdebug.
• Build GitHub releases on CI for great justice.

PsySH v0.7.2

• Fix class not found exception when defining a class which refers to itself.
• Fix a regression when defining custom commands.
• Add support for declare(strict_types=1).

PsySH v0.7.1

• A few tweaks to play nicer with HHVM.
• Fix a bug with self::, parent:: and static:: calls.
• Fix incorrectly suppressed echo '0' output.

PsySH v0.7.0

• 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!)

PsySH v0.6.1

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

PsySH v0.6.0

• Support for PHP Parser v2.0, with better PHP 7 support (Thanks @alexeyshockov, 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!)

PsySH v0.5.2
