What is new in Swamp Converter 0.1.8

First public release of **Swamp Converter**: a menu-bar app for macOS that converts files from a wheel you open by dragging, with a shortcut, or from the Studio window, and downloads links through yt-dlp.

## Install

1. Download **SwampConverter.zip** below and unzip it.
2. Move **Swamp Converter.app** to *Applications* and open it.
3. macOS will say it cannot check the app. Open **System Settings > Privacy & Security**, scroll to *Security*, click **Open Anyway** and confirm. You only do this once: the app is signed ad hoc, without a paid Apple Developer ID.

Requires **macOS 26 (Tahoe) or newer** on an Apple silicon Mac. The guide is in [docs/GUIDE.md](https://github.com/aansonsa/swamp-converter/blob/main/docs/GUIDE.md).

## Good to know

- Video, document and download operations use optional tools (ffmpeg, yt-dlp, LibreOffice, pandoc). They are not bundled; *Settings > Tools* shows what was found.
- macOS may ask for permissions again after an update, because the app is ad-hoc signed.
- Dia and Firefox do not report the open page; select the link or copy the address first.
