Angular Compiler version 12.2.6 brings subtle enhancements over its predecessor, 12.2.5, primarily focusing on refining existing features and stability rather than introducing groundbreaking changes. Both versions, essential for Angular developers, share core functionalities, including compiling Angular templates and components, translating Angular code into efficient JavaScript, and providing critical error diagnostics during the development process. Both depend in the same tslib version. The licensing remains MIT.
The most notable difference lies in the unpackedSize attribute within the dist object. Version 12.2.6 presents a slight increase in size (19497027 bytes) compared to 12.2.5 (19496825 bytes), suggesting minor additions or adjustments to the codebase. The new version was released approximately a week after the older one. While the file count remains the same at 484, the change in unpacked size hints at code optimizations, bug fixes, or possibly even small feature enhancements bundled in the newer release. Developers should always check de official changelog of the library for a more precise description of the changes, but if the difference is so small, normally there aren't big breaking changes between versions. Given the minimal nature of the changes, upgrading from 12.2.5 to 12.2.6 should be relatively straightforward, but always check compatibility with other parts of the Angular project.
