The Protocol Update (v0.9.0)

Highlights

• Multi-protocol support: OpenSCP now expands beyond SFTP with protocol-aware support for SCP, FTP, FTPS, and WebDAV, making the app usable across a much wider range of remote servers and workflows.
• Protocol-aware core architecture: the project now includes a protocol model, capability descriptors, and a protocol-specific client factory so connection logic, transfers, and UI behavior can adapt cleanly to each backend.
• First-class SCP support: SCP is now handled as a real transfer mode, including explicit mode selection, transfer-only workflow handling, and path-based operations for environments where remote listing is not available.
• FTP and FTPS integration: dedicated FTP and FTPS backends were added, including remote directory listing with MLSD/LIST fallback, TLS-related settings, and protocol-aware connection handling.
• WebDAV integration: OpenSCP now supports WebDAV through a dedicated backend built around libcurl and tinyxml2, with scheme, TLS, and persistence support wired into the app.
• Protocol-driven connection experience: connection dialogs, saved sites, quick connect, and remote actions now expose only the settings and actions that apply to the selected protocol, making the UI clearer and safer.
• Improved terminal workflow: Open in terminal was expanded with interactive login support, safer launch behavior, and better fallback handling when a direct terminal integration path is unavailable.
• Usability improvements across the UI: this release adds Home navigation, history dialog support, and dedicated shortcut settings to improve day-to-day remote navigation and workflow control.
• Expanded language support: French was added to the application, while Spanish and Portuguese translations were extended to cover the new protocol-aware flows, settings, and validation messages.
• Stronger testing and dependency coverage: CI, tests, and packaging were extended to cover the new protocol stack, including backend factories, capability logic, FTP/FTPS/WebDAV behavior, and required dependency paths.

Fixes

• Safer FTP and FTPS connection handling: FTP probe behavior now fails cleanly on curl errors and reports response codes more reliably, while HTTP CONNECT tunneling and proxy validation were hardened for these transports.
• Cleaner proxy configuration behavior: proxy defaults are now normalized more carefully, and persisted proxy settings are sanitized to reduce invalid or inconsistent runtime states.
• Protocol-aware action safety: UI actions that do not apply to a given protocol, such as remote permissions in unsupported cases, are now hidden instead of remaining exposed incorrectly.
• More reliable SCP auto behavior: SCP auto mode now falls back to SFTP when runtime read or write operations fail, improving resilience in mixed or restricted environments.
• Localization cleanup: obsolete legacy translation entries were removed and Spanish/Portuguese catalogs were synchronized and polished for better consistency.
• Small UI corrections: local toolbar behavior was refined, including the placement of Home and Open folder actions, and backend-coupled helper declarations were restored more safely where needed.

Upgrade Notes

• This release introduces a breaking configuration rename: build flags, runtime environment variables, CI variables, integration test variables, and related documentation now use the OPENSCP_* prefix.
• If you maintain local scripts, CI jobs, packaging automation, or integration tests, update any remaining references to legacy OPEN_SCP_* names.
• FTPS and WebDAV support add dependency considerations around libcurl, tinyxml2, and protocol-specific TLS behavior, so packagers and contributors should review the updated build and packaging requirements.
• Users upgrading existing saved workflows may notice new protocol-specific connection settings, since protocol selection and capability-aware options are now integrated into connection dialogs, saved sites, and global defaults.
• Terminal integration behavior was updated to support interactive login and safer fallback flows, so users relying on previous Open in terminal assumptions should review the updated settings and documentation.
