Add items when you fix a bug or add a feature (this makes the 25 release process easy :-). 26 27 2. Do a JIRA search for tickets closed since the previous release. 28 29 3. Use the report generated by the maven-changelog-plugin to see all 30 SVN commits. TBA how to use this with SVN. 31 32 To generate the release notes from this file: 33 34 mvn changes:announcement-generate -Prelease-notes [-Dchanges.version=nnn] 35 36 then tweak the formatting if necessary 37 and commit 38 39 The <action> type attribute can be add,update,fix,remove. 40 --> 41 42 <document> 43 <properties> 44 <title>Changes</title> 45 <author email="dev (a] commons.apache.org">Apache Commons developers</author> 46 </properties> 47 48 <!-- NOTE: 49 The description below is specially formatted so as to improve the layout of the generated release notes: 50 The parsing process removes all line feeds, replacing them with a single space. 51 The Velocity template in resources/templates has been enhanced to replace pairs of adjacent spaces 52 with a new-line in the release notes. (These spaces are ignored when displaying HTML). 53 If the output is not quite correct, check for invisible trailing spaces! 54 55 N.B. The release notes template groups actions by type, and only extracts data for the current release. 56 The changes report outputs actions in the order they appear in this file. 57 58 To regenerate the release notes: 59 mvn changes:announcement-generate -Prelease-notes [-Dchanges.version=nnn] 60 61 Defining changes.version allows one to create the RN without first removing the SNAPSHOT suffix. 62 --> 63 64 <body> 65 <release version="6.2" date="2017-12-DD" description="Experimental Java 9 Support"> 66 <action issue="BCEL-294" type="fix" dev="britter" due-to="Mark Roberts">Incorrect comment in StackMap.java</action> 67 <action issue="BCEL-296" type="fix" dev="ggregory" due-to="Mark Roberts">Incorrect comment in several classes.</action> 68 <action issue="BCEL-295" type="fix" dev="ggregory" due-to="Mark Roberts">Fix local variable live range length; add test case.</action> 69 <action issue="BCEL-300" type="fix" dev="ggregory">org.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 19.</action> 70 <action issue="BCEL-301" type="fix" dev="ggregory">org.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 20.</action> 71 </release> 72 73 <release version="6.1" date="2017-09-14" description="Experimental Java 9 Support"> 74 <action issue="BCEL-293" type="add" dev="britter">Add Automatic-Module-Name MANIFEST entry for Java 9 compatibility</action> 75 <action issue="BCEL-292" type="add" dev="markt">Add minimal Java 9 support</action> 76 <action issue="BCEL-286" type="fix" dev="britter" due-to="Mark Roberts">Utility.signatureToString fails if a method has multiple type arguments</action> 77 <action issue="BCEL-287" type="fix" dev="britter" due-to="Mark Roberts">IINC does not handle -128 properly</action> 78 <action issue="BCEL-283" type="fix" dev="britter" due-to="Mark Roberts">Support for StackMap should be different from StackMapTable</action> 79 <action issue="BCEL-289" type="fix" dev="kinow">Crash when parsing constructor of inner classes with parameters annotated</action> 80 <action issue="BCEL-276" type="fix" dev="britter" due-to="Sam Yoon, Mark Roberts">LocalVariableTypeTable is not updated.</action> 81 <action issue="BCEL-277" type="fix" dev="britter" due-to="Sam Yoon">Resolving the String representation of a constant throws NoSuchElementException in case of CONSTANT_NameAndType constant.</action> 82 </release> 83 84 <release version="6.0" date="2016-07-10" description="Apache Commons BCEL 6.0 is a major release supporting the new features 85 introduced in Java 6, 7 and 8. 86 87 88 It requires Java 7 or higher to run. 89 90 91 COMPATIBILITY with 5.2 92 ====================== 93 94 95 Binary compatible - not strictly compatible 96 - The constant interface org.apache.bcel.Constants has been deprecated. Classes 97 which implemented this interface in 5.2 now use the constants defined in the 98 org.apache.bcel.Const class. 99 - The constant interface org.apache.bcel.generic.InstructionConstants has been 100 deprecated. Classes which implemented this interface in 5.2 now use the 101 constants defined in the org.apache.bcel.generic.InstructionConsts class. 102 - Return type of method 'public java.lang.Object getElementAt(int)' in 103 org.apache.bcel.verifier.VerifierFactoryListModel has been changed to 104 java.lang.String. 105 - The BCEL classes do no longer implement java.io.Serializable. 106 107 108 109 Source compatible - Yes, sort of; 110 - The org.apache.bcel.classfile.Visitor interface has been enhanced with 111 additional methods. If you implemented it directly instead of extending 112 the EmptyVisitor class you'll have to implement the new methods. 113 - The org.apache.bcel.generic.Visitor interface has been enhanced with an 114 additional method. If you implemented it directly instead of extending 115 the EmptyVisitor class you'll have to implement the new methods. 116 117 118 Semantic compatible - Yes, except: 119 - BCEL 6.0 handles new attributes such as code annotations that could only 120 be processed by implementing a custom AttributeReader in the previous 121 versions. Code relying on this behavior will have to be adjusted since 122 the AttributeReader will no longer be called in these cases. 123 124 125 126 For full information about API changes please see the
