🎉 Perseus v0.4.0 Goes Stable! 🎉

[arctic-hen7]

Today, after one year of beta versions, I am very happy to announce the stable release of Perseus v0.4.0, the latest major version of the Perseus framework! This version comes not only with a slew of new features and bug fixes, but also a full rewrite of the entire Perseus core, streamlining it to improve speed and reliability. Here are a few of the new features you might like:

• Capsules, which allow you to split your pages into multiple widgets, all with access to Perseus' state generation platform, letting you delay loading parts of your pages trivially to improve load times, while encouraging code reuse and more idiomatic UI development
• An overhauled error management system, now with an intelligent distinction between different types of errors to make sure you never replace working content from the server with an error again
• Improved inbuilt optimizations through the CLI, making sure your app is fast from the second you run perseus deploy
• All state is now cached at the application-level, meaning users who go back to a page they've already visited will get there instantly, with no connection required (this works for capsules too, meaning pages that use the same widgets will load even faster)
• Upgraded to Sycamore v0.8 for faster reactive primitives and greatly improved developer ergonomics
• Added support for custom API routes
• Removed a ton of unnnecessary macros, and greatly improved the developer experience
• Made the CLI automatically install the tools it needs to build and optimize your app: cargo install perseus-cli && perseus new my-app && cd my-app && perseus serve just works, no dependencies needed (except Rust, we're not that good...yet)
• Added a more lightweight translator for inbuilt internationalization to trim down your app's bundle size, improving performance
• Added a panic handling system that lets you do crash analytics and handle critical failures gracefully in your app
• Removed old UI quirks to make styling much easier
• Improved hydration support to make your apps even faster, while fixing untold numbers of bugs
• Added perseus check to let your validate your app more quickly
• Added inbuilt minification of HTML/CSS/JS assets
• Made testing your app literally 2x more ergonomic
• Added server integrations for Axum and Rocket
• Fixed a heck of a lot of bugs!

Finally, I just want to thank the entire Perseus community, for helping us reach 1,300 stars (🤯), and for being so supportive and helpful during this (very long) development period, and throughout the life of the project. This release has a ton of features I've always wanted to see in a web framework, and we couldn't have built it without all your support. Thank you so much!
