v1.2.1 Changes
January 04, 2021🚀 This is a bug release to correct defects found in the previous release. This version should add no additional functionality, though certain bug fixes will correct previous behaviors or add files which were incorrectly excluded due to packaging issues.
🏗 JPype scans jar files and rebuilding missing directories to allow imports from stripped and obfuscated jar files. Previously certain build patterns for jars excluded directories which prevented the import system from functioning properly. This change should increase the number of jar files which can be imported successfully. This was the intended behavior for imports, but certain defects in the process prevented proper function.
🚀 Missing stub files added to packaging. These were added in the last release, but the packaging system incorrectly excluded them from the build.
🏁 Python 3.9 issues are resolved on Windows. A change in Python 3.9 made is so that the GIL is not held during library loading, thus static variables created are not valid. These variables have been moved to module initialization.
🚀 aarch64 has been added to the build patterns for publication in this and future releases.
