Bugfixes and minor changes:

• Fixed a regression causing the automatic renewal of the Let's Encrypt® certificates to not work properly.
• UI: fixed regression causing the Administration Interface port of the last successful connection to not be properly restored.
• UI: fixed a bug where the TLS key appeared to be lost in the interface if certificate generation failed, even though the key was still retained on the server.

Bugfixes and minor changes:

• Fixed an issue with the update mechanism

Bugfixes and minor changes:

• Fixed a regression introduced in 1.9.0, the "public IP or hostname" field on the passive mode page was not restored when opening the settings dialog

Fixed vulnerabilities:

• MSW: Warn if installing the server outside of Program Files due to custom directories having too lax permissions

Bugfixes and minor changes:

• Fixes to the update check mechanism
• Fixed a regression in the converter for old 0.9.x configurations dealing with placeholders in native paths

New features:

• Private keys used for TLS can now be stored on a PKCS#11-compatible token device; the UI has been updated accordingly.

• Fixed bug causing the most recent log file, rather than the oldest, to be deleted upon rotation, when using dates as suffixes.
• MSW: fixed regression causing socket listener conflicts due to recent libfilezilla changes.
• Added WebUI: an HTTP server providing a REST API and a web app for seamless web access to stored files. WebUI is not included in the default build and must be enabled with the --enable-webui parameter during compilation. This feature is experimental; feedback and bug reports are welcome.

Bugfixes and minor changes:

• MSW: Mount points are now case-insensitive so that restrictions on sub mounts cannot be bypassed by a change of character case

Bugfixes and minor changes:

• Fixed a potential deadlock during transfers
• FTP: Fixed potential crash if the session gets closed

Fixed vulnerabilities:

• SFTP: Fixed PuTTY ECDSA NIST P-521 private key recovery vulnerability (CVE-2024-31497). If you use NIST P-521 keys to connect to SSH/SFTP servers, you should regenerate them and revoke the previous ones.
