Commons Lang is a set of utility functions and reusable components that should be of use in any Java environment. Commons Lang 3.6 at least requires Java 7.0. Note that this has changed from Commons Lang 3.5, which only required Java 1.6. For the advice on upgrading from 2.x to 3.x, see the following page: http://commons.apache.org/lang/article3_0.html HIGHLIGHTS ========== Some of the highlights in this release include: o The class org.apache.commons.lang3.concurrent.Memoizer is an implementation of the Memoizer pattern as shown in Goetz, Brian et al. (2006) - Java Concurrency in Practice, p. 108. o The class org.apache.commons.lang3.ArchUtils has been added. ArchUtils is a utility class for the "os.arch" system property. DEPRECATIONS ============ The Apache Commons Community has recently set up the Commons Text component as a home for algorithms working on strings. For this reason most of the string focused functionality in Commons Lang has been deprecated and moved to Commons Text. This includes: o All classes in the org.apache.commons.lang3.text and the org.apache.commons.lang3.text.translate packages o org.apache.commons.lang3.StringEscapeUtils o org.apache.commons.lang3.RandomStringUtils o The methods org.apache.commons.lang3.StringUtils.getJaroWinklerDistance and org.apache.commons.lang3.StringUtils.getLevenshteinDistance For more information see the Commons Text website: http://commons.apache.org/text The class org.apache.commons.lang3.CharEncoding has been deprecated in favor of java.nio.charset.StandardCharsets. The following methods have been deprecated in org.apache.commons.lang3.ArrayUtils in favor of the corresponding insert methods. Note that the handling for null inputs differs between add and insert. o add(boolean[], int, boolean) -> insert(int, boolean[], boolean...) o add(byte[], int, boolean) -> insert(int, byte[], byte...) o add(char[], int, boolean) -> insert(int, char[], char...) o add(double[], int, boolean) -> insert(int, double[], double...) o add(float[], int, boolean) -> insert(int, float[], float...) o add(int[], int, boolean) -> insert(int, int[], int...) o add(long[], int, boolean) -> insert(int, long[], long...) o add(short[], int, boolean) -> insert(int, short[], short...) o add(T[], int, boolean) -> insert(int, T[], T...) COMPATIBILITY WITH JAVA 9 ================== The MANIFEST.MF now contains an additional entry: Automatic-Module-Name: org.apache.commons.lang3 This should make it possible to use Commons Lang 3.6 as a module in the Java 9 module system. For more information see the corresponding issue and the referenced mailing list discussions: https://issues.apache.org/jira/browse/LANG-1338 The build problems present in the 3.5 release have been resolved. Building Commons Lang 3.6 should work out of the box with the latest Java 9 EA build. Please report any Java 9 related issues at: https://issues.apache.org/jira/browse/LANG NEW FEATURES ============ o LANG-1336: Add NUL Byte To CharUtils. Thanks to Beluga Behr. o LANG-1304: Add method in StringUtils to determine if string contains both mixed cased characters.

COMPATIBILITY ============= Apache Commons Lang 3.5 is binary compatible with the 3.4 release. Users should not experience any problems when upgrading from 3.4 to 3.5. There has been an addition to the org.apache.commons.lang3.time.DatePrinter interface: o Added method 'public boolean parse(java.lang.String, java.text.ParsePosition, java.util.Calendar)' o Added method 'public java.lang.Appendable format(long, java.lang.Appendable)' o Added method 'public java.lang.Appendable format(java.util.Date, java.lang.Appendable)' o Added method 'public java.lang.Appendable format(java.util.Calendar, java.lang.Appendable)' For this reason 3.5 is not strictly source compatible to 3.4. Since the DatePrinter interface is not meant to be implemented by clients, this change it not considered to cause any problems. JAVA 9 SUPPORT ============== Java 9 introduces a new version-string scheme. Details of this new scheme are documented in JEP-223 (http://openjdk.java.net/jeps/223). In order to support JEP-223 two classes had to be changed: o org.apache.commons.lang3.JavaVersion deprecated enum constant JAVA_1_9 introduced enum constant JAVA_9 o org.apache.commons.lang3.SystemUtils deprecated constant IS_JAVA_1_9 introduced constant IS_JAVA_9 For more information see LANG-1197 (https://issues.apache.org/jira/browse/LANG-1197). All other APIs are expected to work with Java 9. BUILDING ON JAVA 9 ================== Java 8 introduced the Unicode Consortium's Common Locale Data Repository as alternative source for locale data. Java 9 will use the CLDR provider as default provider for locale data (see http://openjdk.java.net/jeps/252). This causes an number of locale-sensitive test in Commons Lang to fail. In order to build Commons Lang 3.5 on Java 9, the locale provider has to be set to 'JRE': mvn -Djava.locale.providers=JRE clean install We are currently investigating ways to support building on Java 9 without further configuration. For more information see: https://issues.apache.org/jira/browse/LANG-1265 NEW FEATURES ============== o LANG-1275: Added a tryAcquire() method to TimedSemaphore. o LANG-1255: Add DateUtils.toCalendar(Date, TimeZone).

Thanks to Bruno P. Kinoshita, Henri Yandell. o LANG-938: Build fails with test failures when building with JDK 8 ============================================================================= Release Notes for version 3.2 COMPATIBILITY WITH 3.1 ======================== This release introduces backwards incompatible changes in org.apache.commons.lang3.time.FastDateFormat: o Method 'protected java.util.List parsePattern()' has been removed o Method 'protected java.lang.String parseToken(java.lang.String, int[])' has been removed o Method 'protected org.apache.commons.lang3.time.FastDateFormat$NumberRule selectNumberRule(int, int)' has been removed These changes were the result of [LANG-462]. It is assumed that this change will not break clients as Charles Honton pointed out on 25/Jan/12: " 1. Methods "FastDateFormat$NumberRule selectNumberRule(int, int)" and "List parsePattern()" couldn't have been overridden because NumberRule and Rule were private to FastDateFormat. 2. Due to the factory pattern used, it's unlikely other two methods would have been overridden. 3. The four methods are highly implementation specific. I consider it a mistake that the methods were exposed. " For more information see https://issues.apache.org/jira/browse/LANG-462.
