New features

• Universal URLs. These new URLs of Moera pages use a central redirector at moera.page host and include a node name. Read the details in the documentation.

Improvements

• Browser add-on support removed.
• Node now requires Java 17 for running.
• Developers' naming server is now used in development environments.
• Converted all React components to be functional and use React hooks.
• Generation of Node API classes, JSON schemas and routines in TypeScript and Python from Node API definition in YAML.
• Improved the Node API documentation.
• Improved debug logging of Redux actions, making possible to see actions that caused them.
• Made WebSockets connection more reliable.
• Improved accessibility of buttons that have no text on them.
• Set correct dimensions of image placeholders in the text of posts/comments to avoid layout shifts when loading images.
• Use more convenient wording: "create a blog" instead of "sign up", and "log in/out" instead of "connect/disconnect".
• A lot of refactoring in the client.
• Pass node name in X-Moera header.
• Less punctuation and mathematical characters are now allowed in node names (thanks to Eliyahu Duvidzon for proposal).

Speed improvements

• Improved Redux selectors to avoid unnecessary re-rendering of React components.
• Made client initialization process faster.
• Do not request information about the same node many times.
• Migrated from create-react-app scripts.
• Updated all dependencies that had security issues.
• Replaced some minor dependencies with our own code.
• Reduced size of the main bundle of the client by lazy-loading parts of the code that are not needed on the start.
• Moved WebSockets events processing code to a web worker.
• Precompile JSON schemas and perform validation in a web worker.
• Do not build FontAwesome icon library on the start, because it blocks the main thread for a while.
• Avoid duplicate requests to the naming server. Cache names for several naming servers and do not clean the cache after switching user.
• Do not show a loading indicator if loading is fast enough.

Bugfixes

• Remove escaping backslash only when it prepends a smiley (thanks to Tigra for reporting).
• Allow <strike> tag. Use <s> for strikeout in the editor in HTML mode (thanks to Igor Braginsky for reporting).
