Havre 0.3.0

Havre 0.3.0

FluxCatch is now Havre. This release carries the new name and mark, and the design and site work since 0.2.5.

Highlights

• A new name and mark. Havre is the harbour where Monet painted Impression, soleil levant. The mark is a brush-drawn download arrow over a waterline.
• Files save straight into ~/Downloads. No folder of its own is created there; a folder chosen in Settings still takes precedence.
• Site adapters for YouTube (through the yt-dlp already installed on your Mac), Pornhub, MissAV, Jable and The Economist Insider.
• A calmer interface. A still wash of colour in the margins, progress bars in the colour of their state, and one quiet rule between Settings sections.
• A safer sweep. The engine's weekly clean-up of unfinished files now removes only files it wrote, so a browser's .part files in Downloads are left alone.

Upgrading from FluxCatch 0.2.5

1. Replace your unpacked extension folder with the contents of havre-extension-0.3.0.zip. The extension ID does not change, so settings and download history carry over.
2. Unzip havre-native-host-macos-0.3.0.zip and run ./install-macos.sh. It registers the engine under its new name, removes the old registration and runtime copy, and carries a chosen save folder over.
3. Reload Havre at chrome://extensions.

Files saved earlier into ~/Downloads/FluxCatch stay there and stay reachable from the download history.

Requirements

• Google Chrome 116 or newer
• macOS with Python 3.9 or newer; FFmpeg for merging and conversion; yt-dlp for YouTube

Install

1. Unzip havre-extension-0.3.0.zip and load the folder with Load unpacked at chrome://extensions.
2. Unzip havre-native-host-macos-0.3.0.zip and run ./install-macos.sh.

FluxCatch 0.2.5

This release shipped under the product's former name, FluxCatch. The product is now Havre, and Havre 0.3.0 is the current release; its installer carries a 0.2.5 install over and keeps the save folder you chose.

FluxCatch 0.2.5

Product-finish release on top of the 0.2.4 security-truth foundation.

Highlights

• English and Simplified Chinese manifest catalogs (default zh_CN)
• Bounded Instagram/X SPA response observers for allowlisted progressive MP4 saves, reusing Chrome's network path by default
• Reworked Settings IA with dirty-state validation and explicit permission flows; shared UI tokens across popup, Side Panel and Options
• Reproducible packaging bound to the commit identity; CI runs E2E against the exact shipped extension ZIP

Fixed in the field (The Economist / boomi.net HLS case, #6 #7 #8)

• Masterless rendition playlists now group into one card with a resolution dropdown; audio renditions are labeled 仅音频 and never pose as videos again
• Grouped downloads fetch video + best-bandwidth audio playlists in parallel and merge losslessly through FFmpeg
• Manifest fetching is bounded by a 20-second wall-clock watchdog with an explicit 获取播放列表超时 failure state — no more indefinite "connecting"
• The native engine honors the system HTTP/HTTPS proxy for public targets; loopback/private targets remain direct-pinned (FLUXCATCH_DISABLE_SYSTEM_PROXY=1 restores direct-only)

Requirements

• Extension: Google Chrome 116+
• Native engine: macOS, Python 3.9+, FFmpeg for merge/remux/MP3

Install

1. Unzip fluxcatch-extension-0.2.5.zip, load via chrome://extensions → Load unpacked.
2. Unzip fluxcatch-native-host-macos-0.2.5.zip, run ./install-macos.sh, reload FluxCatch.
