igorski/bitmappery is a non-destructive image editor for editing images in the browser. The repository information lists the latest release as 1.2.0. However, the provided information does not say what changed in this version. So instead of pinning down the changes in 1.2.0, it is worth reviewing the features and scope described in the repository.
The editor supports layers and masks, and provides an animation timeline and a sprite sheet editor. Custom brushes and cloud storage integration are also introduced as features. According to the README description, a document is composed of multiple layers, and each layer has content, transformations, and filters. The implementation uses Vue and Vuex, and rendering uses the author's zCanvas. The primary language is TypeScript and the license is MIT. The repository shows 347 stars. This shows the scope of a project that aims to offer several image editing capabilities in one place, but the feature list alone cannot tell you how each feature behaves or how good the editing quality is.
There are clear limits to what can be confirmed. The provided information contains no changelog for 1.2.0, so the improvements or the direction of change in this release cannot be known. Which service the cloud storage integration targets is not stated either. No data backing performance comparisons or editing quality is given as well. So what can be confirmed is limited to the feature composition and the repository metadata, and beyond that there is not enough ground to evaluate the completeness.
