DevsFTP v1.0.1 Release Notes 🚀

Welcome to DevsFTP v1.0.1! This release brings major new performance upgrades, parallel transfer worker pools, direct remote-to-remote migrations, visual directory diffing, and comprehensive reliability hardening across Windows and Linux.

🌟 What's New in v1.0.1

⚡ Parallel Transfer Engine & Concurrency Pools

• Configurable Concurrency: Set max parallel transfers (1 to 10 concurrent streams) in the Transfer Queue toolbar.
• Dynamic Worker Pool: Active Promise.race() pipeline keeps transfer queues saturated at maximum throughput.
• Reliable Cancellation: Stop individual transfers or click Cancel All with instant stream unpiping—zero socket crashes and zero server disconnects.
• Queue Management: Added 🗑️ Clear Cancelled toolbar action alongside 🧹 Clear Completed.

🔄 Remote-to-Remote Direct Transfers

• Transfer files directly between two remote servers (e.g. SFTP to S3, or FTP to WebDAV) without downloading them to your local hard drive first.
• Automated buffer cleanup and stream piping ensure ultra-fast, zero-clutter server migrations.

📝 Pending Edits Watcher & Auto-Sync

• External Editor Watcher: Edit remote files in your favorite local IDE (VS Code, Sublime, Notepad++). DevsFTP automatically detects local saves and syncs them back to the remote server.
• Startup Restore Prompt: On launch, DevsFTP detects unsaved cached edits and prompts you with a selective profile checklist—choose exactly which server profiles to sync or dismiss.

📊 Bandwidth Limiter & Live Analytics

• Dynamic Speed Caps: Set custom upload and download speed limits on the fly using high-performance stream throttling (Unlimited down to 256 KB/s).
• Live Transfer Sparklines: Real-time visual graphs displaying instantaneous transfer speeds, queue progress, and network utilization.

🔍 Directory Compare Tool

• Side-by-Side Visual Diffing: Compare local directory structures against remote server folders.
• Color-Coded File States: Instantly spot missing, newer, older, or modified files between local and remote.
• One-Click Batch Sync: Synchronize differing files directly from the comparison view.

🖥️ Integrated SSH Terminal

• Embedded Xterm Shell: Open full SSH terminal sessions directly inside DevsFTP.
• Configurable Scrollback: Native support for customizable scrollback history (default: 5,000 lines).

🛡️ Reliability & Security Fixes

• Fail-Closed Vault Security: Master password verification fails closed on IPC errors, guaranteeing credential vault security.
• SFTP Stream Pipeline: Replaced non-cancelable fastGet/fastPut with streaming pipelines to eliminate cipher auth tag errors on user cancellation.
• Windows File Lock Recovery: Added 3-step async retry handling on .part file renames to prevent EBUSY / EPERM permission locks on Windows.
• SOCKS5 Dynamic Proxy Hardening: Added bounds checking and exception handling to prevent socket parser errors during dynamic tunnel forwarding.
• Unlimited Audio Chimes: Fixed AudioContext hardware limits to ensure transfer completion chimes play reliably across unlimited transfers.
