These are the release notes and advice for upgrading Joda-Time from version 2.6 to version 2.7.
Joda-Time version 2.7 --------------------- Joda-Time is a date and time handling library that seeks to replace the JDK Date and Calendar classes. This release contains enhancements, bug fixes and a time zone update. The release runs on JDK 5 or later. Joda-Time is licensed under the business-friendly Apache License Version 2. This is the same license as all of Apache, plus other open source projects such as Spring. The intent is to make the code available to the Java community with the minimum of restrictions. If the license causes you problems please contact the mailing list. ** Please also check out our related projects ** ** https://www.joda.org/joda-time/related.html ** Enhancements since 2.6 ---------------------- - Add DateTime.withDate(LocalDate) and DateTime.withTime(LocalTime) [#213] This was possible using DateTime.withFields(ReadablePartial) but the new methods are clearer - Added new system property for time-zone loading [#37] Added system property "org.joda.time.DateTimeZone.Folder". If set, then it is treated as a file system folder to load time-zone data from. The folder is loaded using ZoneInfoProvider and must be the unzipped output of ZoneInfoCompiler. The default behaviour is unchanged, with default time-zone data included in the jar file. - Produce jar file without time-zone data [#220] A second jar file is now located in Maven Central with the classifier "no-tzdb". This is the same as the main joda-time jar file, except that the tzdb data and ZoneInfoCompiler are omitted. This is intended for use by Android, but could be used in other environments. If using this alternative jar, a time-zone system property must be set, either "org.joda.time.DateTimeZone.Provider" or "org.joda.time.DateTimeZone.Folder". The default behaviour in the standard jar file is unchanged, with time-zone data included in the jar file. Compatibility with 2.6 ---------------------- Build system - Yes Binary compatible - Yes Source compatible - Yes Serialization compatible - Yes Data compatible - Yes - DateTimeZone data still at version 2014j Semantic compatible - Yes Deprecations since 2.6 ---------------------- Bug fixes since 2.6 ------------------- - Fix Asia/Dhaka time-zone [#208] Problem caused by time-zone ending at 24:00 on December 31st Model change as being as 23:59:59.999 - Fix PeriodFormatter.withLocale to operate on word-based formatting [#187, #191] Previously, PeriodFormatter.withLocale() had no effect on word-based formatting Now, the locale used when calling PeriodFormat.wordBased(locale) is passed to the PeriodFormatter. In addition, if PeriodFormatter.withLocale(locale) is called, then the word-based pattern will change to a pattern appropriate for that locale. Scala -------- Joda-Time uses annotations from Joda-Convert. In the Java programming language, this dependency is optional, however in Scala it is not. Scala users must manually add the Joda-Convert v1.2 dependency.
