| components that should be of use in any Java environment. Commons Lang 3.3 |
| at least requires Java 6.0. |
| |
| For the advice on upgrading from 2.x to 3.x, see the following page: |

| |
| 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<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. |
| 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. |
