+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Added
+
+- version-aware ffmpeg selection: detect Opera's bundled Chromium version and download the matching nwjs-ffmpeg release instead of always using the latest
+- per-variant Chromium detection via binary inspection (`get_chromium_major`)
+- ffmpeg download caching: skip re-download when multiple Opera variants share the same Chromium version
+
+### Changed
+
+- universal shebang bash interpreter to safely find bash on `$PATH`
+- Widevine CDM is now downloaded once before the main loop instead of redundantly per variant
+- release data is fetched once upfront (`?per_page=50`) and reused for version matching
+
+### Removed
+
+
+### Fixed
+
+- in the preflight check: Prefer our user-friendly error messages while avoiding double error message from the operating system by redirecting also `stderr` to `/dev/null`
+- potential runtime error: prefer `command -v` over `which`-command, which can have different behaviour on different Linux distributions and always use the first result in `PATH` independently of multiple defined commands
+- `grep` error when `CDM_FLAG` starts with `--` by adding explicit end-of-options separator (`grep -qF -- "$CDM_FLAG"`)
