This release has been quickly released to cover some immediate regressions from v2.8.0 as well as patching a new LTS Java feature that affected parsing malformed zip headers. A part of me expected that refactoring \~50% of the codebase would lead to some regressions, but not the ones or quantity we had. Turns out we had no test coverage for the exact format of the `apktool.yml` meta file. Since the test suite decodes and assembles - they were generating a `apktool.yml` on the fly. So the only way this regression was noticed if you were using older `apktool.yml` files against the newest release. We do have [tests](https://github.com/iBotPeaches/Apktool/commit/ca07a0a56cd0ce3418151c8ddc296625f7200026?ref=connortumbleson.com) now to prevent this from happening again. Next we had wide spread build failures on JDK 11 & 17 shortly after the release of v2.8.0 which became apparent with this crash. ``` java.util.zip.ZipException: Invalid CEN header (invalid zip64 extra data field size) ``` Turns out thanks to the research by [evowizz](https://github.com/iBotPeaches/Apktool/issues/3174?ref=connortumbleson.com#issuecomment-1642697602) \- a recent Java update affected some types of applications. > Improved ZIP64 Extra Field Validation (JDK-8302483 (not public)) > java.util.zip.ZipFile has been updated to provide additional validation of ZIP64 extra fields when opening a ZIP file. This validation may be disabled by setting the system property `jdk.util.zip.disableZip64ExtraFieldValidation` to true. So we set some system properties to opt out of this protection. --- **This release had 17 commits by 4 people and 1 robot** - Connor Tumbleson (iBotPeaches) - 11 commits - Igor Eisberg - 3 commits - ArjunaKumarMohanta - 1 commit - Dependabot (BOT) - 1 commit - sv99 - 1 commit --- # Changes since 2.8.0 - \[[#3177](https://github.com/iBotPeaches/Apktool/pull/3177?ref=connortumbleson.com)\] Add JDK 20 to test suite. - \[[#3179](https://github.com/iBotPeaches/Apktool/pull/3179?ref=connortumbleson.com)\] Add `run` command for Gradle inline execution.
