Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

1.2.0 - 2026-06-22

Added

• CORS HTTP headers to example web server configs and the NixOS module.

Changed

• Nix static builds now use the mold linker for faster builds.
• Nix static build is now GMP-free.
• GitHub Pages workflow now runs every six hours instead of daily.

Fixed

• Crash caused by renaming the output file of an existing task.

1.1.0 - 2026-06-13

Added

• Passthrough of new entries from source feed to output feed via passthroughNewEntries config option.
• SSRF protection for source feed URLs — DNS resolution and IP range validation before connecting.
• HTTP 429 (Too Many Requests) detection — treated like 304, falls back to cached feed.
• Source feed deduplication across tasks sharing the same URL.
• Canonicalization of output and cache directory paths.
• ETag and Last-Modified header persistence for conditional feed fetches.
• Configurable User-Agent header via --user-agent CLI option.
• Configurable service username in the NixOS module via the userName option.
• A GitHub Action workflow to generate and host the generated feeds on GitHub Pages.
• devTools parameter throughout the Nix build files for faster Nix shell builds without HLS and other dev tools.

Changed

• Cache files are now per-task instead of per-source, enabling different saveSourceFeedEntries per task for the same source URL. Old cache files are migrated automatically to the new file names.
• Credentials embedded in source feed URLs (e.g., https://token@host/feed) are now redacted from all log output.
• Explicit dependency version bounds.
• Minimum supported GHC version is now 9.10 (Cabal 3.12+), no support for GHC 9.6 and 9.8.

Fixed

• HTTP retry for server errors — retry logic was previously broken because 5xx exceptions bypassed the retry loop. Server errors are now properly retried with exponential backoff.
• Statically-linked build for AArch64 — the Nix GC root was not being created.
• URL credentials in source feed URLs were not being sent with HTTP requests, breaking authentication for feeds that require them. The original URL is now preserved as-is for the request.

Removed

• Legacy cache file migration code.

1.0.0 - 2026-05-22

Added

• Initial release of feed-repeat.
• Feed fetching from RSS, Atom, and RDF source feeds.
• Weighted random selection (A-Res) prioritizing older entries, with per-domain entry limits.
• Per-feed YAML configuration.
• Feed caching to disk.
• Output Atom feeds.
• Conditional fetches via If-Modified-Since header.
• HTTP response body size limit (10 MB), request timeout (30s), and exponential backoff retry.
• URL normalization and relative link resolution in feed entries.
• Tool CLI.
• NixOS module for declarative deployment with nginx reverse proxy.
• systemd service with sandboxing.
• Docker image running as non-root user (UID 1000).
• Example web server configs for nginx, Apache, and Caddy with HSTS and security headers.
