_The release that makes Trilium lighter, more visual and easier to organise: images shrink themselves, attributes get a home of their own, and your backups can finally be restored._

<details>
    <summary>🚨 For ARM64 Docker users</summary>
    <p>The <code spellcheck="false">arm64</code> image is now based on Debian 13 "trixie", as Debian 11 reaches end of life on 2026-08-31. Your host needs a <code spellcheck="false">libseccomp</code> new enough to know the <code spellcheck="false">clone3</code> syscall (roughly 2.5+), or the container will fail to start. If it does, add:</p>
    <pre><code class="language-text-x-yaml">services:
  trilium:
    security_opt:
      - seccomp:unconfined</code></pre>
    <p>Updating Docker itself will not help since <code spellcheck="false">runc</code> links the host's <code spellcheck="false">libseccomp</code>. The 32-bit <code spellcheck="false">linux/arm/v7</code> and <code spellcheck="false">linux/arm/v8</code> images and the native ARM builds are unaffected.</p>
</details>

> [!WARNING]
> **Before you upgrade.** This release contains changes that can break an existing setup.
> 
> 1.  **MCP now requires authentication** and can optionally be accessed over the network. → _Reconfigure your existing MCP clients with credentials._
> 2.  **General HTML support in text notes is now disabled by default.** This makes copy-paste from websites behave well, without grabbing unwanted tags such as input boxes. → _Re-enable via Options → Text notes → Preserve unsupported HTML tags._
> 3.  `**<div>**`**s in text notes are now unwrapped** instead of being preserved as-is, regardless of settings. This prevents broken behaviour when entering new paragraphs, and bugs such as being unable to exit a code block.

##### ✨ Highlights

###### Know what's in your database — and take it back

Two new tools answer the same question from opposite ends: what is actually taking up all that room?

*   **Space Usage** draws it as a treemap — notes, revisions and attachments sized by how much space they take — so the thing quietly eating your disk is visible at a glance instead of guessed at. The **cleanup tool** then acts on what you find: erase deleted notes, trim old revisions, drop unused attachments and compact the database.
*   **Compress images** goes after the usual culprit, resizing oversized pictures and re-saving them smaller — from a note, the tree, the attachments list, the image viewer or the cleanup run itself. It tells you what it found before it starts and what it saved when it finishes.

Automatic compression on upload, paste and import now keeps PNGs as PNGs, leaves already-compressed pictures alone, and runs off the thread serving the app, so a large import no longer freezes Trilium. _(@adoriandoran)_

###### Attributes finally have a home

A dedicated **Attributes** sidebar tab shows owned, inherited and promoted attributes in one clear list, and lets you edit them in place. System attributes are marked with an icon in the
