Release Notes

Kotlin/kotlinx-datetime (org.jetbrains.kotlinx:kotlinx-datetime)

v0.7.1

• Add kotlinx.datetime.Instant and kotlinx.datetime.Clock type aliases to, respectively, kotlin.time.Instant and kotlin.time.Clock to make migration more convenient.
• Add a fallback timezone database implementation for Darwin that uses the Foundation framework if the timezone database is unavailable on the filesystem (#​485).
• Restore binary compatibility in string format definitions utilizing dates on the JVM (#​545).

v0.7.0

Breaking changes:

• Remove kotlinx.datetime.Instant and kotlinx.datetime.Clock in favor of kotlin.time.Instant (#​506). See https://github.com/Kotlin/kotlinx-datetime?tab=readme-ov-file#deprecation-of-instant for a description of what to do if this causes problems.
• Unify the range of admissible LocalDate and LocalDateTime values on all platforms (#​432).
• Rename dayOfMonth to day, monthNumber to month (#​84).
• Make DayOfWeek and Month no longer type aliases to java.time.DayOfWeek and java.time.Month (#​96).
• Make "UTC" and not "Z" be the timezone identifier for TimeZone.UTC (#​474).
• Accept "z" in TimeZone.of, with the same meaning as "Z" (#​529).
• Add DateTimeFormat-based KSerializer implementations for datetime entities, and change the default serializers to be based on toString/parse pairs (#​415).

Additions:

• Add java.io.Serializable implementations for most of the entities in the library (#​143). Thanks for spotting and fixing a potential vulnerability, @​lukellmann!
• Add LocalDateRange, a range of LocalDate values (#​190). Thanks, @​PeterAttardo!
• Add YearMonth and YearMonthRange (#​457).

Tweaks and fixes:

• Support obtaining the system timezone on old Debian-based distributions (#​430).
• Fix not being able to parse some valid timezone identifiers using the timeZoneId() directive (#​444).
• Use the grammar defined in RFC 9557 for parsing timezone identifiers in the timeZoneId() directive, allowing parsing values not present in the timezone database (#​531).
• Improved error messages when formatting an invalid DateTimeComponents value (#​471).
• Set the JPMS dependency on kotlinx.serialization.core to be optional (#​496).
