All notable changes to this project will be documented in this file.

The format is based onKeep a Changelog.This project uses a custom versioning scheme (and notSemantic Versioning).

• API change: due to Issue #159: the author of the algorithm is Eugene Myers, therefore classes and methods were renamed accordingly

• bugfixing new UnifiedDiff reader
  • header for each file
  • skip empty lines
• introduction of Meyers Diff Algorithm with Linear Space improvment (until matured this will not be the default diff algorithm)
• introduction of DiffAlgorithmFactory to set the default diff algorithm DiffUtils use (DiffUtils.withDefaultDiffAlgorithmFactory(MeyersDiffWithLinearSpace.factory());)

• bugfixing on new UnifiedDiff reader / writer for multifile usage
• bugfix for wrong DiffRow type while transforming from a patch that removed a line in one changeset
• introduced change position into UnifiedDiff reader
• introduced first version of conflict output possibility (like GIT merge conflict)
  • moved verification toAbstractDelta
  • introducedConflictOutput toPatch to add optional behaviour to patch conflicts

• make patch serializable

• some bugfixes regarding unified diff writer
• UnifiedDiffReader improved fordeleted file mode and better timestamp recognition
• UnifiedDiffReader improved fornew file mode and better timestamp recognition

• minor bug fixes
• optional include equal parts of original and revised data
• API change: removed DiffException completely
• added possibility toprocess diffs to for instance show whitespace characters

• java-diff-utils is now a multi module project. The main project java-diff-utils now comes without any dependencies.
• started reimplementation of unified diff tools
• Exchange0 += 1 for0 = 1 in UnifiedDiffUtils
• preview of new Unified Diff Reader / Writer. This is not yet feature complete but passes the tests of the old version.
  • feel free to issue some change requests for the api.
• introduces lineNormalizer extension point to e.g. change html code encoding. (issue #41)

• moved to organisationjava-diff-utils
• changed groupid toio.github.java-diff-utils and artifact id tojava-diff-utils

• Introduced a process listener to diff algorithms. For long runningdiffs one could implement some progress information.
• automatic module name for JDK 9 and higher usage

• changed generation of inline diffes, if there are different linefeeds within one diff, then these are excluded from the diff block.

• Due to licensing issues Delta.java and DiffAlgorithm.java were removed.

• released at maven central
• included checkstyle source code conventions
• allow configurable splitting of lines to define the blocks to compare (words, characters, phrases).

• groupid changed tocom.github.wumpz, due to maven central releasing

• support for inline merge
• integrated JGit (Eclipse Licensed) to provide HistogramDiff to gain speed for large datasets

• switch to maven and removed other artifacts
• changed groupid tocom.github.java-diff-utils due to different forks at github
• updated maven plugins
• JDK 1.8 compatibility, sorry if you have to stick with older versions
• restructured packages heavily
• changed API
• changed Algorithm to provide only cursor positions

• removed all kinds of helper classes in favour of new JDK 8 function classes like Predicate

• JDK 1.5 compatibility
• Ant build script
• Generate output in unified diff format (thanks for Bill James)
