  "contentHtml": "<p>Improvements to math, tables, and diagrams in chat, plus Claude prompt caching for agents.</p><ul><li><p><strong>Math rendering:</strong> Math formulas in chat now render more accurately. Added support for <code>\\underbracket</code> and <code>\\overbracket</code>. Also fixed layout issues with fractions, delimiters, and accents.</p></li><li><p>LaTeX math such as <code>\\[ ... \\]</code> and <code>\\( ... \\)</code> sometimes showed up as raw text when the AI response also included code (code blocks or inline code). Those expressions now render properly.</p></li></ul><figure><img src=\"/changelog/media/2026/claude-prompt-cache-sharing-math-rendering-and-more/fc2b1b84a5.webp\" alt=\"A chat proof rendered as formatted equations, with fractions and a greater-than-or-equal comparison\" width=\"1382\" height=\"1492\" loading=\"lazy\" decoding=\"async\"></figure><ul><li><p><strong>Claude prompt cache sharing across agent chats:</strong> Claude prompt caching now reuses an AI agent’s instructions and training files across all chats with that agent. Starting a new chat, or reopening an old one, no longer re-caches the agent’s full context. You are not paying to cache the same agent context again every time you open a chat.</p></li><li><p><strong>Copy and expand tables:</strong> Tables in AI responses now have <strong>Copy table</strong> and <strong>Expand table</strong> buttons. These replace the width toggle. Copy table pastes a formatted table into documents, spreadsheets, and email. In a plain-text editor, it pastes as tab-separated values. Expand table opens the table full screen, with a copy button, so wide tables are easier to read.</p></li><li><p><strong>Mermaid diagrams:</strong> TypingMind can now natively display Mermaid diagrams in the AI’s response without needing a plugin.</p></li></ul><figure><img src=\"/changelog/media/2026/claude-prompt-cache-sharing-math-rendering-and-more/494001d163.webp\" alt=\"A chat response showing a Mermaid bar chart titled Monthly Sales, with bars for January through June\" width=\"2042\" height=\"1572\" loading=\"lazy\" decoding=\"async\"></figure>"
