+                               Version 3.6
+                              Release Notes
+This document contains the release notes for the 3.6 version of
+Apache Commons Lang as well as a history all changes in the Commons Lang 3.x
+release line. 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
+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.
+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
+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...)
+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.

+                        Release Notes for version 3.5
+Some of the highlights in this release include:
+o Added Java 9 detection to org.apache.commons.lang3.SystemUtils.
+o Support for shifting and swapping elements in
+    org.apache.commons.lang3.ArrayUtils.
+o New methods for generating random strings from different character classes
+    including alphabetic, alpha-numeric and ASCII added to
+    org.apache.commons.lang3.RandomStringUtils.
+o Numerous extensions to org.apache.commons.lang3.StringUtils including
+    null safe compare variants, more remove and replace variants, rotation and
+    truncation.
+o Added org.apache.commons.lang3.ThreadUtils - a utility class to work with
+    instances of java.lang.Thread and java.lang.ThreadGroup.
+o Added annotations @EqualsExclude, @HashCodeExclude and @ToStringEclude to
+    mark fields which should be ignored by the reflective builders in the
+    org.apache.commons.lang3.builder package.
+o Support for various modify and retrieve value use cases added to the classes
+    in org.apache.commons.lang3.mutable.
+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
+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 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.
+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
+    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:
+o LANG-1275: Added a tryAcquire() method to TimedSemaphore.
+o LANG-1255: Add DateUtils.toCalendar(Date, TimeZone). Thanks to Kaiyuan Wang.
+o LANG-1023: Add WordUtils.wrap overload with customizable breakable character.

+             to Gokul Nanthakumar C.

+             Gary Gregory.
+o LANG-1253: Add RandomUtils#nextBoolean() method. Thanks to adilek.
+o LANG-1085: Add a circuit breaker implementation. Thanks to Oliver Heger and

+o LANG-1225: Add RandomStringUtils#randomGraph and #randomPrint which match

+             array. Thanks to Krzysztof Wolny.

+o LANG-938:  Build fails with test failures when building with JDK 8
+                        Release Notes for version 3.2
+This release introduces backwards incompatible changes in
+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<Rule> 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.
