3.0.13

This is the last release that RefactoringMiner supports only the Java programming language.
For the next release, we are migrating the project to a multi-language support infrastructure.

3.0.12

Core Improvements

1. Improve precision and recall in Benchmark 2 [current precision is ~99% and recall ~98%]
2. Support Parameterize Test detection with @MethodSource (in addition to @CsvSource and @ValueSource)
3. Infer the detection of moved code between files (without the presence of calls) based on other moved methods between the two files #1010
4. Further improve the matching of statements with assert-related migrations in tests (AssertJ fluent assertions)

UI Improvements

1. Added tooltips for the following scenarios:

• References to type declarations being renamed or moved
• References to method declarations being renamed
• References to variable/field declarations being renamed or moved

2. Improved diff visualization for overlapping refactorings within moved code

3. Support matching string arguments in Parameterize Test refactorings

4. Support renames in module-info diff

3.0.11

UI Improvements

1. Show Pull Request Code Review Comments #930

2. Tooltips for moved code with links to move diffs #912 + refactoring-aware tooltips for moved code #886

3. Show detected refactorings with link to the corresponding AST diff page #893

4. Synchronized expansion/collapse based on mappings #881 #888

5. Support Java-reserved keywords permits, implements, throws, extends in the diff #887

Core Improvements

1. Support package-info.java and module-info.java files.
2. Support Extract/Inline Method for small expressions being part of larger statements.
3. Multi-threaded fetch of files in commits and pull requests is paused to avoid HTTP errors.
4. New Java language features supported: Pattern Matching for instanceof
5. Improved support for matching statements with assert-related migrations in tests (AssertJ fluent assertions).
6. Support assertThatThrownBy migration in tests.
7. Support refactoring detection and AST diff for a commit range.
8. Support Perforce P4 centralized version control system. Thanks to @dmazinanian

Benchmarks

New benchmark from the paper titled "An Automated Approach to Discovering Software Refactorings by Comparing Successive Versions" is added. The validation is still in progress.
