3.9.3 - 2020-02-20

Fixed

  • For v1 UUIDs, round down for timestamps so that microseconds do not bump the timestamp to the next second.

As an example, consider the case of timestamp 1 with 600000 microseconds (1.600000). This is the first second after midnight on January 1, 1970, UTC. Previous versions of this library had a bug that would round this to 2, so the rendered time was 1970-01-01 00:00:02. This was incorrect. Despite having 600000 microseconds, the time should not round up to the next second. Rather, the time should be 1970-01-01 00:00:01.600000. Since this version of ramsey/uuid does not support microseconds, the microseconds are dropped, and the time is 1970-01-01 00:00:01. No rounding should occur.

3.9.2 - 2019-12-17

Fixed

  • Check whether files returned by /sys/class/net/*/address are readable before attempting to read them. This avoids a PHP warning that was being emitted on hosts that do not grant permission to read these files.

3.9.1 - 2019-12-01

Fixed

  • Fix RandomNodeProvider behavior on 32-bit systems. The RandomNodeProvider was converting a 6-byte string to a decimal number, which is a 48-bit, unsigned integer. This caused problems on 32-bit systems and has now been resolved.

3.9.0 - 2019-11-30

Added

  • Add function API as convenience. The functions are available in the Ramsey\Uuid namespace.
    • v1(int|string|null $node = null, int|null $clockSeq = null): string
    • v3(string|UuidInterface $ns, string $name): string
    • v4(): string
    • v5(string|UuidInterface $ns, string $name): string

Changed

  • Use paragonie/random-lib instead of ircmaxell/random-lib. This is a non-breaking change.
  • Use a high-strength generator by default, when using RandomLibAdapter. This is a non-breaking change.

Deprecated

These will be removed in ramsey/uuid version 4.0.0:

  • MtRandGenerator, OpenSslGenerator, and SodiumRandomGenerator are deprecated in favor of using the default RandomBytesGenerator.

Fixed

  • Set ext-json as a required dependency in composer.json.
  • Use PHP_OS instead of php_uname() when determining the system OS, for cases when php_uname() is disabled for security reasons.

3.8.0 - 2018-07-19

Added

  • Support discovery of MAC addresses on FreeBSD systems
  • Use a polyfill to provide PHP ctype functions when running on systems where the ctype functions are not part of the PHP build
  • Disallow a trailing newline character when validating UUIDs
  • Annotate thrown exceptions for improved IDE hinting

3.7.3 - 2018-01-19

Fixed

  • Gracefully handle cases where glob() returns false when searching /sys/class/net/*/address files on Linux
  • Fix off-by-one error in DefaultTimeGenerator

Security

  • Switch to random_int() from mt_rand() for better random numbers

3.7.2 - 2018-01-13

Fixed

  • Check sysfs on Linux to determine the node identifier; this provides a reliable way to identify the node on Docker images, etc.

3.7.1 - 2017-09-22

Fixed

  • Set the multicast bit for random nodes, according to RFC 4122, §4.5

Security

  • Use random_bytes() when generating random nodes

3.7.0 - 2017-08-04

Added

  • Add the following UUID version constants:
    • Uuid::UUID_TYPE_TIME
    • Uuid::UUID_TYPE_IDENTIFIER
    • Uuid::UUID_TYPE_HASH_MD5
    • Uuid::UUID_TYPE_RANDOM
    • Uuid::UUID_TYPE_HASH_SHA1

3.6.1 - 2017-03-26

Fixed

  • Optimize UUID string decoding by using str_pad() instead of sprintf()

3.6.0 - 2017-03-18

Added

  • Add InvalidUuidStringException, which is thrown when attempting to decode an invalid string UUID; this does not introduce any BC issues, since the new exception inherits from the previously used InvalidArgumentException

Fixed

  • Improve memory usage when generating large quantities of UUIDs (use str_pad() and dechex() instead of sprintf())

3.5.2 - 2016-11-22

Fixed

  • Improve test coverage

3.5.1 - 2016-10-02

Fixed

  • Fix issue where the same UUIDs were not being treated as equal when using mixed cases

3.5.0 - 2016-08-02

Added

  • Add OrderedTimeCodec to store UUID in an optimized way for InnoDB

Fixed

  • Fix invalid node generation in RandomNodeProvider
  • Avoid multiple unnecessary system calls by caching failed attempt to retrieve system node

3.4.1 - 2016-04-23

Fixed

  • Fix test that violated a PHP CodeSniffer rule, breaking the build

3.4.0 - 2016-04-23

Added

  • Add TimestampFirstCombCodec and TimestampLastCombCodec codecs to provide the ability to generate COMB sequential UUIDs with the timestamp encoded as either the first 48 bits or the last 48 bits
  • Improve logic of CombGenerator for COMB sequential UUIDs

3.3.0 - 2016-03-22

Security

3.2.0 - 2016-02-17

Added

  • Add SodiumRandomGenerator to allow use of the PECL libsodium extension as a random bytes generator when creating UUIDs

3.1.0 - 2015-12-17

Added

  • Implement the PHP Serializable interface to provide the ability to serialize/unserialize UUID objects

3.0.1 - 2015-10-21

Added

3.0.0 - 2015-09-28

The 3.0.0 release represents a significant step for the ramsey/uuid library. While the simple and familiar API used in previous versions remains intact, this release provides greater flexibility to integrators, including the ability to inject your own number generators, UUID codecs, node and time providers, and more.

Please note: The changelog for 3.0.0 includes all notes from the alpha and beta versions leading up to this release.

Added

  • Add a number of generators that may be used to override the library defaults for generating random bytes (version 4) or time-based (version 1) UUIDs
    • CombGenerator to allow generation of sequential UUIDs
    • OpenSslGenerator to generate random bytes on systems where openssql_random_pseudo_bytes() is present
    • MtRandGenerator to provide a fallback in the event other random generators are not present
    • RandomLibAdapter to allow use of ircmaxell/random-lib
    • RandomBytesGenerator for use with PHP 7; ramsey/uuid will default to use this generator when running on PHP 7
    • Refactor time-based (version 1) UUIDs into a TimeGeneratorInterface to allow for other sources to generate version 1 UUIDs in this library
    • PeclUuidTimeGenerator and PeclUuidRandomGenerator for creating version 1 or version 4 UUIDs using the pecl-uuid extension
  • Add a setTimeGenerator method on UuidFactory to override the default time generator
  • Add option to enable PeclUuidTimeGenerator via FeatureSet
  • Support GUID generation by configuring a FeatureSet to use GUIDs
  • Allow UUIDs to be serialized as JSON through JsonSerializable

Changed

  • Change root namespace from "Rhumsaa" to "Ramsey;" in most cases, simply making this change in your applications is the only upgrade path you will need—everything else should work as expected
  • No longer consider Uuid class as final; everything is now based around interfaces and factories, allowing you to use this package as a base to implement other kinds of UUIDs with different dependencies
  • Return an object of type DegradedUuid on 32-bit systems to indicate that certain features are not available
  • Default RandomLibAdapter to a medium-strength generator with ircmaxell/random-lib; this is configurable, so other generator strengths may be used

Removed

  • Remove PeclUuidFactory in favor of using pecl-uuid with generators
  • Remove timeConverter and timeProvider properties, setters, and getters in both FeatureSet and UuidFactory as those are now exclusively used by the default TimeGenerator

Fixed

  • Improve GUID support to ensure that:
    • On little endian (LE) architectures, the byte order of the first three fields is LE
