### Performance
* The custom SMBJ and WebDAV clients achieve 1 Gbps network speeds over Wi-Fi 7, so after v1.11.x the image reader defaults to have image caching disabled.
* Windows 11 JXR HDR screenshots can be displayed in fp16 hdr bitmaps, or transcode to Ultra HDR Jpeg.
* The image loader was tweaked for preloading and decoding 100MB jpg hdr files over network without any OOM crashes, and smaller files should load instantly.
* Accurate HDR presentation of RAW and JXR images (compared with DaVinci Resolve).

| JXL HDR PQ | 16-bit integer | PQ |
| JPEG HDR | 8-bit base + gain map | sRGB base, HDR reconstruction |
| AVIF HDR | 10-bit; 12-bit at Lossless | sRGB base + ISO gain map |
| AVIF HDR PQ | 10-bit; 12-bit at Lossless | PQ |

### To use WebDAV
``openssl req -x509 -newkey rsa:4096 -keyout server.key -out server.crt -days 365 -nodes``
```.\rclone.exe serve webdav "D:\" --addr :8443 --cert .\server.crt --key .\server.key --read-only --user admin --pass password```
### To use SMB3 encryption:
`Get-SmbShare | Select-Object Name, EncryptData`
`Set-SmbShare -Name "Media" -EncryptData $true`
`Set-SmbServerConfiguration -RejectUnencryptedAccess $false -Force`
```
while ($true) {
Clear-Host
$config = Get-SmbServerConfiguration
$sessions = Get-SmbSession
Write-Host "--- SMB SERVER ENCRYPTION STATUS ---" -ForegroundColor Cyan
Write-Host "Global Server Encryption Enabled : $($config.EncryptData)"
Write-Host "Reject Unencrypted Access : $($config.RejectUnencryptedAccess)"
Write-Host "Active Sessions : $(($sessions).Count)"
Write-Host "Timestamp : $(Get-Date -Format 'HH:mm:ss')"
Write-Host "------------------------------------`n"
if ($sessions) {
$sessions | Select-Object ClientComputerName, ClientUserName, Dialect, NumOpens | Format-Table -AutoSize
}
Start-Sleep -Seconds 1
}
