4.0.2

Fixed

• Lock 4.0.x to ~8.0.0 to indicate it does not support PHP 8.1.

3.9.5

Fixed

• Indicate support for PHP 8.1, using ~8.1.0 to prevent installations on 8.2 until the library is ready.

4.2.1

Fixed

• Fix soft BC break with Uuid::fromString() signature. The change from string to non-empty-string on the parameter annotation introduced a BC break for those using static analysis tools. This release reverts this change and provides an assertion to guard against empty strings. See ramsey/uuid#383.

4.2.0

Added

• Add Ramsey\Uuid\Exception\UuidExceptionInterface for all ramsey/uuid exceptions to implement. See ramsey/uuid#340.

Fixed

• Fix serialization of UUIDs. See ramsey/uuid#361.

3.9.4

Fixed

• Allow installation of paragonie/random_compat v9.99.100 (for PHP 8 compatibility).

4.1.1

Fixed

• Allow use of brick/math version 0.9

4.1.0

Changed

• Improve performance of Uuid::fromString(), Uuid::fromBytes(), UuidInterface#toString(), and UuidInterface#getBytes(). See PR #324 for more information.

4.0.1

Fixed

• Fix collection deserialization errors due to upstream allowed_classes being
  set to false. For details, see ramsey/uuid#303
  and ramsey/collection#47.

4.0.0

---

Added

• Add support for version 6 UUIDs, as defined by http://gh.peabody.io/uuidv6/,
  including the static method Uuid::uuid6(), which returns a
  Nonstandard\UuidV6 instance.
• Add ability to generate version 2 (DCE Security) UUIDs, including the static
  method Uuid::uuid2(), which returns an Rfc4122\UuidV2 instance.
• Add classes to represent each version of RFC 4122 UUID. When generating new
  UUIDs or creating UUIDs from existing strings, bytes, or integers, if the UUID
  is an RFC 4122 variant, one of these instances will be returned:
  • Rfc4122\UuidV1
  • Rfc4122\UuidV2
  • Rfc4122\UuidV3
  • Rfc4122\UuidV4
  • Rfc4122\UuidV5
  • Rfc4122\NilUuid
• Add classes to represent version 6 UUIDs, GUIDs, and nonstandard
  (non-RFC 4122 variant) UUIDs:
  • Nonstandard\UuidV6
  • Guid\Guid
  • Nonstandard\Uuid
• Add Uuid::fromDateTime() to create version 1 UUIDs from instances of
  \DateTimeInterface.
• The \DateTimeInterface instance returned by UuidInterface::getDateTime()
  (and now Rfc4122\UuidV1::getDateTime()) now includes microseconds, as
  specified by the version 1 UUID.
• Add Validator\ValidatorInterface and Validator\GenericValidator to allow
  flexibility in validating UUIDs/GUIDs.
  • The default validator continues to validate UUID strings using the same
    relaxed validation pattern found in the 3.x series of ramsey/uuid.
  • Introduce Rfc4122\Validator that may be used for strict validation of
    RFC 4122 UUID strings.
  • Add ability to change the default validator used by Uuid through
    FeatureSet::setValidator().
  • Add getValidator() and setValidator() to UuidFactory.
• Add Provider\Node\StaticNodeProvider to assist in setting a custom static
  node value with the multicast bit set for version 1 UUIDs.
• Add the following new exceptions:
  • Exception\BuilderNotFoundException -
    Thrown to indicate that no suitable UUID builder could be found.
  • Exception\DateTimeException -
    Thrown to indicate that the PHP DateTime extension encountered an
    exception/error.
  • Exception\DceSecurityException -
    Thrown to indicate an exception occurred while dealing with DCE Security
    (version 2) UUIDs.
  • Exception\InvalidArgumentException -
    Thrown to indicate that the argument received is not valid. This extends the
    built-in PHP \InvalidArgumentException, so there should be no BC breaks
    with ramsey/uuid throwing this exception, if you are catching the PHP
    exception.
  • Exception\InvalidBytesException -
    Thrown to indicate that the bytes being operated on are invalid in some way.
  • Exception\NameException -
    Thrown to indicate that an error occurred while attempting to hash a
    namespace and name.
  • Exception\NodeException -
    Throw to indicate that attempting to fetch or create a node ID encountered
    an error.
  • Exception\RandomSourceException -
    Thrown to indicate that the source of random data encountered an error.
  • Exception\TimeSourceException -
    Thrown to indicate that the source of time encountered an error.
  • Exception\UnableToBuildUuidException -
    Thrown to indicate a builder is unable to build a UUID.
• Introduce a Builder\FallbackBuilder, used by FeatureSet to help decide
  whether to return a Uuid or Nonstandard\Uuid when decoding a
  UUID string or bytes.
• Add Rfc4122\UuidInterface to specifically represent RFC 4122 variant UUIDs.
• Add Rfc4122\UuidBuilder to build RFC 4122 variant UUIDs. This replaces the
  existing Builder\DefaultUuidBuilder, which is now deprecated.
• Introduce Math\CalculatorInterface for representing calculators to perform
  arithmetic operations on integers.
• Depend on brick/math for the
  Math\BrickMathCalculator, which is the default calculator used by this
  library when math cannot be performed in native PHP due to integer size
  limitations. The calculator is configurable and may be changed, if desired.
• Add Converter\Number\GenericNumberConverter and
  Converter\Time\GenericTimeConverter which will use the calculator provided
  to convert numbers and time to values for UUIDs.
• Introduce Type\Hexadecimal, Type\Integer, Type\Decimal, and Type\Time
  for improved type-safety when dealing with arbitrary string values.
• Add a Type\TypeInterface that each of the ramsey/uuid types implements.
• Add Fields\FieldsInterface and Rfc4122\FieldsInterface to define
  field layouts for UUID variants. The implementations Rfc4122\Fields,
  Guid\Fields, and Nonstandard\Fields store the 16-byte,
  binary string representation of the UUID internally, and these manage
  conversion of the binary string into the hexadecimal field values.
• Introduce Builder\BuilderCollection and Provider\Node\NodeProviderCollection.
  These are typed collections for providing builders and node providers to
  Builder\FallbackBuilder and Provider\Node\FallbackNodeProvider, respectively.
• Add Generator\NameGeneratorInterface to support alternate methods of
  generating bytes for version 3 and version 5 name-based UUID. By default,
  ramsey/uuid uses the Generator\DefaultNameGenerator, which uses the standard
  algorithm this library has used since the beginning. You may choose to use the
  new Generator\PeclUuidNameGenerator to make use of the new
  uuid_generate_md5() and uuid_generate_sha1() functions in
  ext-uuid version 1.1.0.

Changed

• Set minimum required PHP version to 7.2.
• This library now works on 32-bit and 64-bit systems, with no degradation in
  functionality.
• By default, the following static methods will now return specific instance
  types. This should not cause any BC breaks if typehints target UuidInterface:
  • Uuid::uuid1 returns Rfc4122\UuidV1
  • Uuid::uuid3 returns Rfc4122\UuidV3
  • Uuid::uuid4 returns Rfc4122\UuidV4
  • Uuid::uuid5 returns Rfc4122\UuidV5
• Accept Type\Hexadecimal for the $node parameter for
  UuidFactoryInterface::uuid1(). This is in addition to the int|string types
  already accepted, so there are no BC breaks. Type\Hexadecimal is now the
  recommended type to pass for $node.
• Out of the box, Uuid::fromString(), Uuid::fromBytes(), and
  Uuid::fromInteger() will now return either an Rfc4122\UuidInterface
  instance or an instance of Nonstandard\Uuid, depending on whether the input
  contains an RFC 4122 variant UUID with a valid version identifier. Both
  implement UuidInterface, so BC breaks should not occur if typehints use the
  interface.
• Change Uuid::getFields() to return an instance of Fields\FieldsInterface.
  Previously, it returned an array of integer values (on 64-bit systems only).
• Uuid::getDateTime() now returns an instance of \DateTimeImmutable instead
  of \DateTime.
• Make the following changes to UuidInterface:
  • getHex() now returns a Type\Hexadecimal instance.
  • getInteger() now returns a Type\Integer instance. The Type\Integer
    instance holds a string representation of a 128-bit integer. You may then
    use a math library of your choice (bcmath, gmp, etc.) to operate on the
    string integer.
  • getDateTime() now returns \DateTimeInterface instead of \DateTime.
  • Add __toString() method.
  • Add getFields() method. It returns an instance of Fields\FieldsInterface.
• Add the following new methods to UuidFactoryInterface:
  • uuid2()
  • uuid6()
  • fromDateTime()
  • fromInteger()
  • getValidator()
• This library no longer throws generic exceptions. However, this should not
  result in BC breaks, since the new exceptions extend from built-in PHP
  exceptions that this library previously threw.
  • Exception\UnsupportedOperationException is now descended from
    \LogicException. Previously, it descended from \RuntimeException.
• Change required constructor parameters for Uuid:
  • Change the first required constructor parameter for Uuid from
    array $fields to Rfc4122\FieldsInterface $fields.
  • Add Converter\TimeConverterInterface $timeConverter as the fourth
    required constructor parameter for Uuid.
• Change the second required parameter of Builder\UuidBuilderInterface::build()
  from array $fields to string $bytes. Rather than accepting an array of
  hexadecimal strings as UUID fields, the build() method now expects a byte
  string.
• Add Converter\TimeConverterInterface $timeConverter as the second required
  constructor parameter for Rfc4122\UuidBuilder. This also affects the
  now-deprecated Builder\DefaultUuidBuilder, since this class now inherits
  from Rfc4122\UuidBuilder.
• Add convertTime() method to Converter\TimeConverterInterface.
• Add getTime() method to Provider\TimeProviderInterface. It replaces the
  currentTime() method.
• Provider\Node\FallbackNodeProvider now accepts only a
  Provider\Node\NodeProviderCollection as its constructor parameter.
• Provider\Time\FixedTimeProvider no longer accepts an array but accepts only
  Type\Time instances.
• Provider\NodeProviderInterface::getNode() now returns Type\Hexadecimal
  instead of string|false|null.
• Converter/TimeConverterInterface::calculateTime() now returns
  Type\Hexadecimal instead of array. The value is the full UUID timestamp
  value (count of 100-nanosecond intervals since the Gregorian calendar epoch)
  in hexadecimal format.
• Change methods in NumberConverterInterface to accept and return string values
  instead of mixed; this simplifies ...

4.0.0-beta2

Added

• Add missing convenience methods for Rfc4122\UuidV2.
• Add Provider\Node\StaticNodeProvider to assist in setting a custom static
  node value with the multicast bit set for version 1 UUIDs.

Changed

• Provider\NodeProviderInterface::getNode() now returns Type\Hexadecimal
  instead of string|false|null.
