🐛 Bug fixes

• Fix LocalDateTime::plusNanos() and minusNanos() within the same second (#136 by @gnutix)

🐛 Bug fixes

• ZonedDateTime::of() and LocalDateTime::atTimeZone() failed for years beyond 9999 (#135 by @gnutix)
• toNativeDateTime() and toNativeDateTimeImmutable() on LocalDateTime and ZonedDateTime failed for years beyond 9999 and negative years (#135 by @gnutix)
• ZonedDateTime::toNativeDateTime() and toNativeDateTimeImmutable() returned the wrong offset during a DST overlap (#135 by @gnutix)

⚡️ Performance optimizations

• Faster ZonedDateTime::of(), ofInstant() and toNativeDateTime(), and TimeZoneOffset::toNativeDateTimeZone() for UTC (#135 by @gnutix)

⚡️ Performance optimizations

• Object-identity short-circuit in isEqualTo() and compareTo() (#130 by @gnutix)

✨ New features

• LocalDate::getMonthDay() returns the month-day of the date (#134 by @joelbutcher)

💥 Breaking changes

• Instant::toISOString() and ZonedDateTime::toISOString() now always include seconds, to be RFC 3339 compliant (#131 by @dualfroz)

💥 Breaking changes

• Minimum PHP version is now 8.2
• The following classes are now final:
  • YearMonthRange
  • ZonedDateTime
  • Parser\DateTimeParseException

✨ Compatibility improvements

• The following parser and parse methods now accept hours only in timezone offsets, such as +01 equivalent to +01:00 (#123 by @antonkomarev):
  • IsoParsers:timeZoneOffset()
  • TimeZoneOffset::parse()
  • ZonedDateTime::parse()

💥 Breaking changes

• Duration::toISOString() and __toString() now output negative durations as -P... (#122 by @BastienClement)
  Example: -PT2H21M instead of PT-2H-21M.
  This aligns with ISO 8601-2:2019 and improves compatibility with the JavaScript Temporal API.

🐛 Bug fixes

• ZoneDateTime incorrectly handled DST Transitions with relative time addition (#115)

✨ New features

• LocalDate::getQuarter() and getQuarterValue() return the quarter of the year (#114 by @pscheit)

💥 Breaking changes

• DayOfWeek:
  • deprecated method of() has been removed, use DayOfWeek::from() instead
  • the following deprecated methods have been removed, use enum values instead:

    • DayOfWeek::wednesday() → DayOfWeek::WEDNESDAY
    • DayOfWeek::thursday() → DayOfWeek::THURSDAY
    • DayOfWeek::friday() → DayOfWeek::FRIDAY

    • DayOfWeek::sunday() → DayOfWeek::SUNDAY
  • deprecated method getValue() has been removed, use $dayOfWeek->value instead
  • deprecated method is() has been removed, compare values with $dayOfWeek or $dayOfWeek->value instead

• DefaultClock:
  • deprecated method travel() has been removed, use travelTo() instead
• LocalDate:
  • deprecated method getDay() has been removed, use getDayOfMonth() instead

🔧 Improvements

• Methods returning int are now type-annotated with int ranges
