Filter by type:

v0.3.7

2026-08-22
View Release on GitHub
Added
  • Browser Extension Bundling & Packaging (scripts/build-extensions.sh): Added a unified extension build system (make extensions) producing both packed (.zip for Chrome/Chromium, .xpi for Firefox) and unpacked directory trees with path-tailored INSTALL.txt guides. Bundled extensions across all packaging targets: Windows setup, macOS .app bundle, macOS .pkg, Linux .deb/.rpm, and release archives.
  • CRX Signing & Enterprise Policy Packaging: Added Chromium .crx generation and signing (--crx-key, HYDRA_CRX_KEY, --crx) with pinned extension ID (jpnonmbbkjdpeebdhkjoliklfhkdcomj) for enterprise policy deployments (ExtensionSettings / ExtensionInstallForcelist).
  • Rubber-Band Drag Selection (hydra-gui): Added interactive marquee drag selection to the download table, allowing users to click and drag across rows to select multiple downloads simultaneously.
  • ABI Specification (docs/ffi/ABI.md): Added the canonical specification for the libhydra C ABI — FFI design principles, formal ABI 1 stability policy, full ownership/encoding/error/threading contracts, and compatibility matrix.
  • Frozen ABI Baseline (crates/hydra-ffi/abi/abi-1.manifest): Added a machine-checkable record of ABI 1 — enumerator values, field offsets, width, struct size, and exported symbols.
  • ABI Stability Gate (scripts/ffi-abi-compat.sh, make ffi-compat): Added a CI gate that derives layout from the header with a C probe and enforces ABI 1 rules against the frozen baseline.
  • Forward-Compatibility Probe (examples/ffi-c/compat_probe.c): Added old-header/new-library conformance verification program across release tags.
  • Wider ABI CI Matrix: Expanded FFI conformance testing to Clang on Linux, and stability gates across Linux, macOS, and Windows.
Fixed
  • PowerShell Execution Policy in Windows Installer (install.ps1): Fixed native messaging host registration failure on Windows machines with Restricted PowerShell execution policies by invoking install-native-host.ps1 with -ExecutionPolicy Bypass.
  • MSVC Guard Index Cast & MSYS2 Legacy Header Checkout: Fixed unsigned pointer cast in compatibility probe for MSVC and resolved legacy release header checkouts under MSYS2 environments.
Changed & Refactored
  • libhydra as a First-Class Product: Documentation now draws an explicit boundary between hydra (GPL application) and libhydra (permissively licensed embeddable engine with independent compatibility promises).

v0.3.6

2026-08-22
View Release on GitHub
Added
  • hydra compat-link CLI Subcommand (hydra-cli): Added dedicated subcommand to plan, verify, and install wget and curl dialect symlinks/shims into $PATH or custom directories with shadowing checks.
  • macOS Application Bundle In-Place Updates (hydra-updater / hydra-gui): Added full updater support for macOS .app bundles (Hydra Download Manager.app), re-stamping bundle versions and applying ad-hoc signatures.
  • Elevated Self-Updates (hydra-updater / hydra-gui): Added native authentication prompts (osascript on macOS, pkexec/sudo on Linux) for updating root-owned system installations in-place.
  • Windows Apps & Features Integration (install.ps1 / uninstall.ps1): Registered Hydra in Windows Installed apps / Apps & features with display icons, publisher info, and direct uninstaller links.
  • Desktop & Start Menu Shortcuts (install.ps1): Added Start Menu and optional Desktop (-Desktop) shortcut generation with embedded high-res icons.
  • Offline Windows Uninstaller Packaging: Bundled uninstall.ps1 into Windows release archives for complete offline uninstallation of files, shortcuts, PATH entries, and registry items.
Fixed
  • Immediate Transport Failure Range Reclaim (hya-net / hya-core): Fixed long stalls on closed pooled connections or refused sockets by immediately reclaiming pending byte ranges.
  • Stale In-Flight Range Discard (hya-core): Added request start timestamping to prevent discarded or superseded chunks from being credited after a stall.
  • Repeated Boolean Flags in CLI Dialects (hydra-cli): Fixed dialect canonicalizer rejecting repeated flags like curl -s -sS or wget -q -q.
  • Sudo User Directory Resolution (install.sh / uninstall.sh): Resolved $SUDO_USER when executed via sudo to properly place desktop icons and native messaging manifests in the user's home directory.
  • macOS Application Unregistration & Graceful Quit: Added Launch Services unregistration (lsregister -u) and graceful AppleScript quit messaging before removing the bundle.
  • Windows Process Locking During Upgrades: Added graceful window close requests and process termination for running instances before file replacement.
Changed & Refactored
  • FFI Metric Definition Clarity: Clarified stall_count in hydra_progress_t and hydra_metrics_t to account for range reclaims from both timeouts and connection failures.
  • Update Dialog Elevation Guidance (hydra-gui): Added notices in the update dialog when an update will prompt for administrator privileges across 10 supported languages.

v0.3.5

2026-08-21
View Release on GitHub
Added
  • C/C++ Foreign Function Interface (libhydra / hydra-ffi): Added stable C ABI bindings and header (include/hydra.h) to embed Hydra's engine in C, C++, Python, Swift, Go, etc.
  • Self-Update Engine & CLI Command (hydra-updater / hydra-cli): Added hydra update command with automatic GitHub release discovery and direct asset downloads.
  • GUI In-App Updater (hydra-gui): Added automated update checking on launch, interactive update modal dialog with rendered markdown notes, and single-click restart finisher.
  • Periodic Download Quotas & Rollover (hydra-gui): Added configurable data usage limits over rolling periods (hourly, daily, weekly, monthly) with visual progress gauges.
  • Homebrew Formula Support: Added official Homebrew tap distribution for macOS and Linux CLI installations (brew install ja7ad/tap/hydra).
  • Multi-language Localization: Added full localization across 10 locales (ar, en, es, fa, fr, ja, ko, nl, ru, zh).
Fixed
  • Dynamic Live Speed Limiter: Fixed rate limit adjustments so speed throttling takes effect immediately mid-flight without connection teardown.
  • Paired Aggregate & Per-Job Rate Limiting: Enforced both global engine bandwidth ceilings and individual download caps simultaneously.
  • FTP Download Speed Limiting: Integrated Pace rate limiting into FtpFetcher for unshaped FTP transfers.
  • Linux Application ID & Taskbar Icon: Fixed window icon grouping on GNOME/KDE/Wayland desktops by registering dev.ja7ad.hydra AppID.

v0.2.3

Added
  • Baseline Public Release: Core adaptive concurrency retrieval engine, segmented HTTP/HTTPS/FTP download engine, terminal TUI queue manager, native desktop GUI, and browser extension integrations for Chrome, Firefox, Edge, and Safari.
