 ## [Unreleased]
+
 ### Planned
-- Network deployment options or network log storing
+- HTML report export with charts and graphs
+- Baseline comparison mode (compare current vs. previous test run)
+- Skip flags (`-SkipCPU`, `-SkipNetwork`, etc.) for targeted testing
+- CSV export for data analysis
+- Memory leak detection module
+- Audio device testing
+- Intel Arc GPU support
+- Network deployment options / centralized log storage
 - Multi-language support
+
+---
+
+## [2.4.0] - 2026-04-23
+
+### Fixed
+
+**Network — Latency Test**
+- `$targetPort` was never defined, causing `Test-NetConnection` to receive `Port=0` and throw a
+  validation error on every run — latency test now correctly runs as ICMP-only with no port argument
+- `Test-NetConnection -InformationLevel Detailed` removed; it requires a valid port and is
+  unnecessary for basic ping latency measurement
+- `PsPing` was called with `IP:Port` format instead of bare IP for ICMP mode
+- `PsPing` result regex was too strict — minor whitespace variations in output caused results to be
+  silently dropped; regex now uses flexible `\s*` matching
+- Added debug output line showing raw PsPing tail when parsing still fails, making future
+  diagnosis possible without re-running the test
+
+**Network — Speed Test**
+- Single hardcoded Hetzner HTTPS URL failed under VPN/proxy TLS interception (Mullvad, Tailscale,
+  corporate proxies) with no fallback — replaced with a 3-URL chain: Cloudflare, Hetzner HTTP, OVH
+- Added per-attempt SSL certificate validation bypass to handle MITM interception; bypass is
+  scoped to the request and restored immediately after each attempt regardless of success or failure
+- Added minimum file size check (1000 bytes) to prevent a firewall error page from being recorded
+  as a successful download result
+
+**Network — Recommendations**
+- Virtual and VPN adapters (VMware VMnet, Hyper-V vEthernet, Tailscale, Mullvad, WireGuard,
+  TAP-Windows, OpenVPN) were incorrectly flagged as "slow physical NICs" at 100 Mbps
+- Recommendation engine now iterates adapter lines individually and excludes known virtual/VPN
+  adapter name patterns before applying the slow-speed check
+
+**Reports — Output Location**
+- Reports were saving to the script root directory; now saved to a `Reports\` subfolder
+- `Reports\` folder is created automatically on first report generation
+- Energy report (`powercfg /energy`) redirected into `Reports\` alongside text reports
+- Write-access test updated to target `Reports\` folder; error messages now include the specific
+  path that failed
+
+**Reports — Encoding**
+- Report files written as UTF-8 caused Unicode bullets (`•`) and arrows (`→`) to render as
+  mojibake (`• â†'`) in Notepad and legacy text viewers
+- Switched `Out-File` encoding from UTF8 to ASCII throughout report generation
+- Replaced all Unicode bullet (`•`) characters with `*` and arrow (`→`) characters with `->`
+- Removed Unicode box-drawing characters (`└─`) from PowerShell menu display strings
+- Script file is now fully 7-bit ASCII — no encoding surprises in any editor or viewer
+
+**Batch Launcher**
+- Sysinternals Suite auto-download used a single HTTPS URL with no SSL bypass — same VPN/proxy
+  TLS interception issue as the PS1 speed test; same fix applied
+- `VERIFY` section exit-code branching silently swallowed function output, producing misleading
+  success messages regardless of actual result; simplified to direct output display
+- Stale reference to legacy `SystemTester_FIXED.ps1` filename removed from error message
+- EXIT screen updated to show correct `Reports\` subfolder path
+
+---
+
+## [2.21.0] - 2025-09-02
+
+### Added
+- Tool integrity verification with digital signature checking for all Sysinternals executables
+- Dual report system: timestamped Clean Summary and Detailed output saved as separate `.txt` files
+- Batch launcher (`SystemTester.bat`) with reliable admin elevation and interactive menu
+- GPU Tools Manager — batch menu option 6 for managing NVIDIA, AMD, and GPU-Z testing utilities
+- Enhanced GPU testing: multi-GPU support, NVIDIA-SMI integration, AMD driver detection via registry
+- DirectX diagnostics via `dxdiag`, OpenGL registry check, hardware-accelerated GPU scheduling detection
+- Windows Update integration — checks pending updates, lists titles and classifications, reports service status
+- WHEA hardware event log scan covering last 7 days
+- Network speed and latency testing (initial implementation: `Test-NetConnection`, `PsPing`)
+- Launcher awareness detection — script detects if launched via batch file for context-aware messages
+- `Test-OSHealth` — runs DISM `/ScanHealth` and SFC for OS integrity (admin only)
+- `Test-StorageSMART` — collects health status and media type from physical disks
+- `Test-Trim` — checks SSD TRIM enablement status via `fsutil`
+- `Test-NIC` — captures active network adapter details including link speed and MAC address
+- `Test-GPU` — GPU and display configuration with DirectX and OpenGL information
+- `Test-Power` — battery status and `powercfg /energy` report generation (admin only)
+- `Test-HardwareEvents` — WHEA error log scan
+- Support for additional Sysinternals tools: `sigcheck`, `contig`, `diskext`, `listdlls`, `clockres`
+- `-AutoRun` parameter for unattended full-suite execution with automatic report generation
+- Color-coded console output (green/yellow/red) for all test results and recommendations
+- Recommendations engine — dynamically generated findings covering memory, CPU, disk, SMART,
+  TRIM, network, GPU drivers, Windows Update, and WHEA events
+- GPU sub-menu options: `12a` (basic info), `12b` (vendor-specific), `12c` (GPU memory)
+- GPU-Z download assistant with file size validation in batch launcher
+
+### Fixed
+- Memory usage calculation: `FreePhysicalMemory` (reported in KB) was not being converted
+  correctly, causing inflated usage percentages
+
+### Changed
+- Admin elevation method replaced: `net session` check swapped for PowerShell
+  `WindowsPrincipal.IsInRole` with `FLTMC` as fallback — more reliable on systems where the
+  Server service is disabled
+- Interactive menu expanded to 18 options
+- Report executive summary now includes total tests, success/failure counts, success rate, and duration
+- Detailed report output cleaned and limited to first 40 lines per tool to reduce file size
+
+---
+
+## [2.0.0] - 2024-11-01
+
+### Added
+- Complete rewrite with modular function structure
+- Interactive menu system with numbered options
+- Recommendations engine (initial version)
+- Improved report formatting with section headers
+
+### Changed
+- Monolithic script refactored into discrete test functions
+- All WMI calls migrated to CIM instances for better performance and PowerShell 7 compatibility
+
+---
+
+## [1.0.0] - 2024-01-01
+
+### Added
+- Initial release
+- Core Sysinternals tool runner: `psinfo`, `coreinfo`, `pslist`, `handle`, `clockres`, `autorunsc`, `du`
+- Basic system information collection (OS, CPU, RAM, storage)
+- Single text report output
+- Manual Sysinternals installation required
