Angular Common library version 4.4.5 represents a subtle but important iteration over its predecessor, version 4.4.4, focusing on stability and compatibility within the Angular ecosystem. Both versions provide essential directives and services crucial for building Angular applications, sharing the same core functionality described as "commonly needed directives and services." The key difference lies in the peer dependency: v4.4.5 requires @angular/core version 4.4.5, while v4.4.4 depends on @angular/core version 4.4.4. This signifies that the newer version is specifically built and tested to work seamlessly with the corresponding @angular/core release, ensuring better synchronization and potentially addressing bug fixes or performance improvements introduced in the core framework.
For developers considering an upgrade, this peer dependency is the most critical factor. Using @angular/common 4.4.5 necessitates also upgrading to @angular/core 4.4.5 to maintain compatibility and prevent potential runtime errors. Conversely, if your project relies on @angular/core 4.4.4, sticking with @angular/common 4.4.4 is the safer option. The release dates also give an indication: version 4.4.5 was released on October 12, 2017, roughly two weeks after version 4.4.4's release on September 28, 2017, indicating a relatively quick patch release. Both versions rely on tslib version ^1.7.1, suggesting no significant changes were needed in terms of Typescript library dependencies.
