2.12.1

• Security: the filesystem API refuses access to dot-prefixed files and directories, consistent with space listings.
• Fix: HTTP file validators respect If-None-Match precedence, and file reads and conditional writes tolerate proxies that weaken or transform ETags.
• Fix: YAML data blocks split only on standalone --- lines; X-Ray includes attributes added during indexing.
• Fix: system.reboot() preserves external edits and clears cached widgets. Reopening a page restores a remembered scroll position of zero.
• Fix: the [[Runtime API]] returns JSON for query rows, null values, dates and other Lua values without serialization crashes, and remains usable after the client reloads its UI.
• SLIQ errors offer more specific explanations for common mistakes.
• Public spaces expose robots.txt and a sitemap of content pages, with canonical URLs and descriptions in the initial HTML. Metadata pages are excluded from the sitemap and marked noindex; encoded page names render correctly, frontmatter is hidden, and missing pages return HTTP 404. Read-only spaces show a “Page not found” view with a link home.
• Client builds remove stale bundle chunks and omit source maps from release binaries.
