These are the release notes and advice for upgrading Joda-Time from version 2.8 to version 2.9.

Joda-Time version 2.9

Joda-Time is a date and time handling library that seeks to replace the JDK
Date and Calendar classes. For Java SE 8 and later, please use java.time instead.

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.

Enhancements since 2.8
- Faster parsing of time-zone identifiers [#282]

- Added Interval.parseWithOffset(String) [#299, #296]
  Provides a way to parse the fixed offset in an interval string

- Add DateTimeFormatter methods for StringBuilder [#298]

- Add Russian period translations [#320]

- Add Italian period translations [#312]

- Add Czech period translations [#313]

- Clarify that PeriodFormatterBuilder is in an invalid state once built [#309]

- Allow DateTime and Interval to refer to values at Long.MIN_VALUE and Long.MAX_VALUE [#297, #190]
  A DateTime may be created with any millisecond value, however at the very edges there may be
  some undesirable effects, for example always using UTC instead of the time-zone

- Better error message for malformed tzdb files [#319]

- Better error message for interval constructor [#321]

Compatibility with 2.8
Build system - Yes

Binary compatible - Yes

Source compatible - Yes

Serialization compatible - Yes

Data compatible - Yes

Semantic compatible - Yes

Bug fixes since 2.8
- Fixed to handle JDK 8u60 [#288, #291]
  Without this fix, formatting a time-zone will print "+00:00" instead of "GMT" for the GMT time-zone

- Fix parsing of basic form ISO style where year has unnecessary plus sign [#86]
  For example, +20151030 will now be correctly parsed as year 2015.

- Fix overflow bug in intervals [#315]

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.
