@ -19,6 +19,17 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
- The [`segments`](./admin/configuration/expressions.mdx#segments) function was added for splitting a path into its slash-separated segments.
- When issuing a challenge, Anubis stores information about that challenge into the store. That stored information is later used to validate challenge responses. This works around nondeterminism in bot rules. ([#917](https://github.com/TecharoHQ/anubis/issues/917))
- When parsing [Open Graph tags](./admin/configuration/open-graph.mdx), add any URLs found in the responses to a temporary "allow cache" so that social preview images work.
- Proof of work solving has had a complete overhaul and rethink based on feedback from browser engine developers, frontend experts, and overall performance profiling.
- One of the biggest sources of lag in Firefox has been eliminated: the use of WebCrypto. Now whenever Anubis detects the client is using Firefox (or Pale Moon), it will swap over to a pure-JS implementation of SHA-256 for speed.
- Web Workers are stored as dedicated JavaScript files in `static/js/workers/*.mjs`.
- Pave the way for non-SHA256 solver methods and eventually one that uses WebAssembly (or WebAssembly code compiled to JS for those that disable WebAssembly).
- Legacy JavaScript code has been eliminated.
- The contact email in the LibreJS header has been changed.
- The hard dependency on WebCrypto has been removed, allowing a proof of work challenge to work over plain (unencrypted) HTTP.
### Breaking changes
- The "slow" frontend solver has been removed in order to reduce maintenance burden. Any existing uses of it will still work, but issue a warning upon startup asking administrators to upgrade to the "fast" frontend solver.
