 # v0.103.0: Removal of axios
 The `api.axios` library has been removed from the backend scripting API.
 
-Axios was marked as deprecated at least since April 2024 in favor of the native `fetch()` API, which is available in both browser and Node.js environments. After two years of deprecation, the library was removed following the [March 2026 npm supply chain compromise](https://www.malwarebytes.com/blog/news/2026/03/axios-supply-chain-attack-chops-away-at-npm-trust), where attackers published malicious versions that deployed a remote access trojan. The Trilium's main developer almost got compromised, but `pnpm` not trusting unknown post-install scripts successfully avoided that.

 Scripts that attempt to use `api.axios` will now throw an error with migration instructions.

+# v0.103.0: `cheerio` is now deprecated
+The `api.cheerio` library is deprecated and will be removed in a future version.
+
+## Reasoning
+
+Cheerio is only used for the scripting API while the server internally uses `node-html-parser` for HTML parsing. Removing `cheerio` reduces bundle size and maintenance overhead.
+
+## Migration
+
+Before (`cheerio`):
+
+```javascript
+const $ = api.cheerio.load(html);
+const title = $('h1').text();
+const links = $('a').map((i, el) => $(el).attr('href')).get();
+```
+
+After (`htmlParser`):
+
+```javascript
+const root = api.htmlParser.parse(html);
+const title = root.querySelector('h1')?.textContent;
+const links = root.querySelectorAll('a').map(a => a.getAttribute('href'));
+```
