Version 1.0.0

 X make permissions in the lowest bits of flags to simplify using them [Greg]
 X implement ini handler for phar.readonly and phar.require_hash that allows
   enabling it on PHP_INI_ALL if it is disabled in the system, but does not
   allow disabling it if it is enabled in the system [Greg]
 X implement reading in metadata in manifest as <len32><metadata...> [Marcus]
 X implement writing out of metadata to new manifest [Marcus]
 X if SPL is disabled, enable only static methods of class Phar and disable
   class PharFileInfo completely [Marcus]
 X implement in-phar locking, so that a file that is opened for reading can't
   have a handle opened for writing [Marcus/Greg]
 X docs on file format/manifest description [Greg]
 X docs on uses [Greg]
 X stream context for specifying compression of a file [Marcus]
 X stream context for specifying meta-data [Greg]
 X Phar->begin()/Phar->commit() for specifying a new stub to the phar,
   and deferring flush until all modifications are complete [Greg]
 X Phar->getStub() for retrieving the stub of the phar [Marcus]
 X add setUncompressed(), setCompressedGZ() and setCompressedBZ2() to
   PharFileInfo class [Greg]
 X add uncompressAllFiles(), compressAllFilesGZ() and compressAllFilesBZ2()
   to Phar class [Greg]
 X add PharFileInfo::setMetaData($metadata) [Marcus]
 X add PharFileInfo::getMetaData() [Marcus]
 X always throw exceptions from the Phar object, and E_RECOVERABLE_ERROR from
   streams interface [Greg]
 X Phar archive metadata Phar::setMetaData($metadata) Phar::getMetaData()
   [Greg]
 X support rename() in stream wrapper [Greg]
 X update docs to reflect changes in error handling [Greg]
 X fix 011.phpt, 029.phpt for uncaught exceptions causing bad cleanup
   [Marcus/Greg]

Version 1.1.0

 X Ability to connect a phar file 'phar://whatever' to a directory. That way
   all access to that phar archive are directed to the extracted directory.
   This allows to have the installed files and the archive keep the same
   includes. [Marcus]
 X add SHA-2 (256, 512) support [Marcus]
 X setSignatureAlgorithm() and Phar::MD5 Phar::SHA1 Phar::SHA256 Phar::SHA512
   Phar::PGP to choose the kind of signature to use (PGP falls back to SHA1)
   [Greg]

Version 1.2.0

 X add PharFileInfo::hasMetadata(), PharFileInfo::delMetadata() [Marcus]
 X add Phar::hasMetadata(), Phar::delMetadata() [Marcus]
 X fix Phar::CanWrite() [Marcus]
 X add preliminary phar command (phar.php) [Marcus] 
 X add phar command (phar.phar) [Marcus]
 X list all available compression methods using
   Phar::getSupportedCompression() [Marcus]
 X Remove RINIT [Marcus]

Version 1.2.1

 X Add Phar::getAlias() [Marcus]
 X Add Phar::setAlias() [Greg]
 X Make -a optional in pack subcommand of phar.phar [Marcus]
 X Make Phar::loadPhar() and Phar::mapPhar() ignore extracted archives

Version 2.0.0

 X implement webPhar() rewrite as a callback that returns FALSE to deny
   access, or a string representing a file within the archive to access. If
   unknown, the callback should return the original request uri [Greg]
 X rework filename detection so that alias is always checked first [Greg]
 X make aliases containing '/' or '\' invalid [Greg]
 X implement manual mounting of external phar archives to locations inside a
   phar path, $phar->mount('/path/to/external.phar', 'internal/path');
   this would traverse external.phar's manifest, and add each entry as a
   virtual entry just like automatic mounting of internal phars [Greg]
 X implement manual mounting of external paths to a directory inside a phar
   path.  Because the mapping would be to an external directory, write access
   would be allowed always.  This allows storing sqlite databases, cache, or
   template files in a location external to the phar.  Copy of the files
   would need to be performed in an installation step, phar would not attempt
   to do this for performance and security reasons. [Greg]
 X implement opendir support for mounted paths [Greg]
 X make convertToZip/convertToTar rename files [Steph]
 X make convertTo*() with full file compression rename to append .gz or .bz2
   [Steph]
 X don't automatically add a stub to .zip or .tar files [Steph]
 X don't allow a stub or alias to be added to a .zip/.tar that does not have
   ".phar" in the filename (or already have stub/alias) [Steph]
 X allow read/write on .tar/.zip files that do not contain a stub or alias [Steph/Greg]
 X prevent manual addition of stub via $a['.phar/stub.php'] = '<?php my stub'; [Greg]
 X investigate potential collision between SPL's DirectoryIterator flags and
   those in phar_archive_data [Steph]
 X compression should work for non-phar archives [Steph]
 X implement initial support for simple zip/tar archives (PharData) [Steph]
 X make createDefaultStub() setDefaultStub() and have it file format-specific
   [Steph]
 X convertTo*() should always use the default stub [Steph]
 X ability to store empty directories [Greg]
 X tar support [Greg]
 X zip support [Greg]
 X Phar::copy($from, $to); [Greg]
 X Phar::delete($what) [Greg]
 X Phar::buildFromIterator(Iterator $it[, string $base_directory]) [Greg]
 X Layout: Option to compress all content rather than single files. (tar/phar
   only) [Greg]
 X clean crap paths like phar://blah.phar/file//../to\\here.php [Greg]

Version 2.1.0
 * implement write support for mounted files even if phar.readonly=1
 * implement automatic "mounting" of internal phar archives so that
   phar:///path/to/archive.phar/internal.phar/file opens internal.phar and
   maps its manifest inside archive.phar. The manifest entry inside
   archive.phar would be named "internal.phar/file". Write access to internal
   files inside an internal phar would be denied, as the entire archive must
   be added or removed at the same time.
