Full Changelog: v0.5.0...v0.5.1

v0.5.0

[v0.5.0] - 2026-06-23

Security

• Path traversal protection: all file endpoints validate paths against configured log_dirs and log_files via canonicalize() + allowlist check
• Token authentication: optional Bearer token via config.toml, TAILR_TOKEN env var, or Settings UI
• CSRF protection: restricted CORS headers + X-Requested-With check on POST endpoints
• Config write protection: POST /api/config/log-levels requires authentication when token is set
• Error sanitization: generic error messages to client, detailed errors logged server-side
• Search parameter limits: context capped at 50, limit capped at 10000

Features

• Token input dialog: auto-popup on 401, auto-reload file list after authentication
• Token setting in Settings dialog (persisted to localStorage)

Full Changelog: v0.4.0...v0.5.0

v0.4.0

Features

• Settings dialog: modal design (VS Code style) replacing sidebar panel, with left navigation (General, Log Levels, About)
• Configurable log levels: 7 presets (General, Java, Python, PHP, Go, Rust, syslog), web UI for editing levels/keywords/colors with drag-and-drop reorder
• Font customization: font family dropdown (JetBrains Mono, Hack, Cascadia Code, Fira Code, Consolas, Monaco, Menlo, System Monospace) and font size (10–24px)
• Theme modes: Light, Dark, and System (follows OS preference), persisted across sessions
• Page title dynamically shows selected log file name (tailr - <filename>)
• About page with project logo, version, and GitHub link
• Warp-inspired dark theme color palette
• Full i18n support for all settings strings (en-US, zh-CN)

Fixes

• Selection toolbar scoped to log viewer area only (no longer appears on other UI elements)
• Font size input uses @change to avoid fighting user keystrokes during typing
• Theme mode persisted to localStorage, restored on dialog reopen
• setTimeout timers properly cleared on component unmount

Infrastructure

• frontend/dist removed from git tracking, added to .gitignore

New Contributors

• @godwinjavaee made their first contribution in #2
• @wunamesst made their first contribution in #3

Full Changelog: v0.3.1...v0.4.0

v0.3.1

Performance

• Reverse-read tail: LineIndex::tail_start() reads backwards from EOF in 8KB chunks instead of scanning entire file (440MB log: 1.4s → 43ms)
• Wrap blocking tail I/O in spawn_blocking to avoid async executor stalls

Fixes

• Dark mode text selection contrast (yellow → blue)
• Clippy derivable_impls lint: derive Default for DaemonConfig

Infrastructure

• CONTRIBUTING.md, PR/Issue templates, CI workflow

v0.3.0

What's New in v0.3.0

📄 Config File Support

• Add ~/.config/tailr/config.toml config file with auto-initialization
• Priority: CLI args > Config file > Env vars > Defaults
• tailr init — create config file (prompt to confirm if exists)
• tailr config — print config file contents
• Default config includes log = ["/var/log"] and bind = "0.0.0.0:7700"

🔧 CLI Subcommand Refactoring

• tailr init — initialize config file
• tailr config — print config file contents
• tailr stop — stop daemon (was --stop)
• tailr status — show daemon status (was --status)
• tailr systemd — generate systemd service file (was --systemd)
• tailr launchd — generate launchd plist file (was --launchd)
• tailr upgrade — unchanged

🐛 Bug Fixes

• Upgrade now jumps directly to the latest version regardless of version gap (self_update's compatibility check restricted 0.x versions to same-minor patch bumps only)
• Fixed sidebar overlapping statusbar in the grid layout

⚠️ Breaking Changes

CLI flags changed to subcommands:

tailr --stop      → tailr stop
tailr --status    → tailr status
tailr --systemd   → tailr systemd
tailr --launchd   → tailr launchd

v0.1.5

v0.1.5 - File Truncation Fix

Fixes

• Fixed empty entries after file truncation: When a log file is truncated (e.g., via logrotate copytruncate), the cached LineIndex had stale offsets from the larger file. Now detects truncation (file_size < idx.file_size) and rebuilds the index from scratch.

Full Changelog: v0.1.4...v0.1.5

v0.1.4

v0.1.4 - Daemon Mode

Features

• Daemon mode: Run tailr in background with --daemon, replacing nohup approach
• Process management: --stop to stop running daemon, --status to check status
• System service integration: --systemd generates systemd service file (Linux), --launchd generates launchd plist (macOS)
• PID file management: Automatic PID file handling with custom path support via --pid-file
• Log redirection: stdout/stderr redirected to log file in daemon mode, customizable with --log-file
• Signal handling: Graceful shutdown on SIGINT/SIGTERM/SIGHUP
• Version display: Show current version and GitHub link in settings panel footer

Usage

# Start in background
tailr --daemon --log /var/log/app /var/log/nginx

# Check status
tailr --status

# Stop daemon
tailr --stop

# Generate systemd service file
tailr --systemd --log /var/log/app | sudo tee /etc/systemd/system/tailr.service

# Generate launchd plist (macOS)
tailr --launchd --log /var/log/app > ~/Library/LaunchAgents/com.tailr.plist

Dependencies

• Added daemonize = "0.5" - Unix daemonization
• Added dirs = "5.0" - Cross-platform data directories

Fixes

• Fixed empty entries after file truncation: When a log file is truncated (e.g., via logrotate copytruncate), the cached LineIndex had stale offsets from the larger file. Now detects truncation and rebuilds the index.
• Fixed daemon mode failing to serve HTTP (fork must happen before tokio runtime)
• Fixed test_filter_by_pattern_regex test failure (use builder pattern to compile regex)
• Fixed settings footer hidden behind status bar
