The final version of Angular 9 was released in February 2020, which means the road to Angular 10 has begun. We are keeping close tabs on the new releases. After three release candidates, Angular 9.1.0 has arrived, and it will be the last v9.x release before work on Angular 10 begins.

Updated 26 March, 2020

The speed of Angular releases is picking up! Just yesterday, we wrote about the third release candidate for Angular 9.1.0, and now the final version has arrived. Angular 9.1.0 adds new features including support for TypeScript 3.8, performance improvements, and a long list of bug fixes.

On the Angular Blog, Stephen Fluin shared the future plans for Angular:

This is the last planned minor release for 9.x. As we start work towards 10.0, you should expect to see 10.0 prereleases usually once per week, even though they will contain only minimal changes at first.

Here’s what’s new in the latest minor version:

Updated 25 March, 2020

Three new release candidates for Angular 9.1.0 have arrived. These release candidates mostly fix some bugs, preparing for the update.

9.1.0-rc.2 includes a new feature for the compiler and adds dependency info and ng-content selectors to metadata. From the pull request:

This commit augments the FactoryDef declaration of Angular decorated classes to contain information about the parameter decorators used in the constructor. If no constructor is present, or none of the parameters have any Angular decorators, then this will be represented using the null type. Otherwise, a tuple type is used where the entry at index i corresponds with parameter i.

9.1.0-rc.0 updates TypeScript to version 3.8 and fixes some issues with Ivy compatibility. It also optimizes ngcc performance and reliability and i18n now supports RTL locale info.

From the changelog, below are all the new bug fixes that 9.1.0-rc.2, rc.1, and rc.0 include:

  • common: let KeyValuePipe accept type unions with null (#36093) (407fa42), closes #35743
  • elements: correctly handle setting inputs to undefined (#36140) (e066bdd)
  • elements: correctly set SimpleChange#firstChange for pre-existing inputs (#36140) (447a600), closes #36130
  • ngcc: use path-mappings from tsconfig in dependency resolution (#36180) (6defe96), closes #36119
  • ngcc: use preserve whitespaces from tsconfig if provided (#36189) (aef4323), closes #35871

  • ngcc: do not crash on entry-point that fails to compile (#36083) (ff665b9)
  • ngcc: do not crash on overlapping entry-points (#36083) (c9f554c)

Updated 19 March, 2020

No rest for Angular. One week after the most recent update, Angular 9.1.0-next.5 is here.

Between all of the usual bug fixes, this update also increases performance and speed with some new tweaks. Source map flattening has been sped up (see the original pull request) and modifies the `generatedSegment` properties in mappings so that they link directly to the following segment. The position of SegmentMarkers will also now be stored in order to avoid further unnecessary computation.

The previously time-consuming task of the DirectoryWalkerEntryPointFinder traversing the entire node_modules library has also been changed to save time. It now stores and re-uses the path to entry-points.

From the changelog, here’s the full list:

Updated 11 March, 2020

Just days after Angular 9.1.0-next.3, Angular updated with 9.1.0-next.4. This update mostly focuses on fixes bugs, providing a more stable release. Included in the bug fixes is a new LockFile implementation, using a child-process and some issues with fixed flaky test cases.

In addition, TypeScript 3.8 is now supported. This is currently the latest edition of TypeScript, so be sure to check out what new breaking changes and improvements it adds. Among the list of new features, TypeScript 3.8 includes support for ECMAScript private fields, type-only imports and exports, and top-level await.

9.1.0-next.4 reduces directory traversing, which will reduce the amount of time that findEntryPoints takes 9701.143ms to 4177.278ms.

Here are all the changes in this edition:

Features

Performance Improvements

Updated 9 March, 2020

Hot on the heels of the most recent update comes Angular 9.1.0-next.3. This update includes a long list of bug fixes and performance improvements. Among these improvements includes added micro benchmarks for both destroy hook invocation and host bindings. This improvement closes several pull requests on the topic.

Meanwhile, two new features have been added. Modularization of the Language Service’s diagnostic messages will help centralize error messages and prepares Angular for potential additional features such as annotating diagnostics. (View the original pull request for more information.) In addition to this, now Angular adds zone configuration to TypeScript interfaces.

Let’s have a look at all the newest bug fixes in this release:

Features

Performance Improvements

Updated 2 March, 2020

Angular 10 is scheduled to arrive in May 2020. On the way to the new major version, Angular 9.1.0-next.2 has been released. This beta adds several bug fixes for different areas, including animations, core, language-service and ngcc. For example, in animations, a false positive is no longer returned when detecting Node in Webpack builds and the ɵAnimationDriver has been removed from private exports.

New features have been added for ngcc, bazel and zone.js, whereas the core and Ivy have received performance improvements. Take a look at all that has happened in the beta release as well as in the two previous betas:
