| ==== General ==== | ==== General ==== | ||
| - | * 5.16: Consider size of linked file when transferring/synchronizing symbolic link. [[bug>1747]] | + | * 6.4: Limiting SFTP version to 3 with non-well-known SFTP servers as a workaround for interoperability issues. [[bug>2247]] |
| - | * 5.16: Installer does not support Windows XP/2003 anymore. WinSCP application itself still runs on Windows XP/2003. Use //Portable executables// download. | + | * 6.4.1: Dropped support for Windows XP and Windows Vista. Minimal supported version is Windows 7. |
| - | ==== GUI ==== | + | ===== In the Last Major Release 6.2/6.3 (after October 2023) ===== |
| - | ··* 5.16: Removed option to create //Quick Launch// icons (Windows Vista and older only). | + | ==== General ==== |
| - | ==== Scripting and .NET Assembly ==== | + | ··* 6.2: SSL (3.0) is no longer supported. TLS 1.0 and 1.1 are disabled by default, to match the OpenSSL 3 defaults. |
| - | * 5.16: TLS/SSL certificate fingerprints in generated URL use dashes (''-'') instead of colons ('':''), while colons are still accepted. Consequently URLs with TLS/SSL certificate fingerprints generated by 5.16 and newer cannot be used for older versions. | ||
| - | * 5.16: SHA-256 fingerprints in generated URL use dashes (''-'') and underscores (''_'') instead of pluses (''+'') and slashes (''/''), while pluses and slashes are still accepted. Consequently URLs with SHA-256 fingerprints generated by 5.16 and newer cannot be used for older versions. | ||
| - | * 5.16: ''RemoteFileInfo.FileType'' now consistently returns ''L'' for symlinks as was always documented. ''RemoteFileInfo.FileType'' now consistently returns uppercase value as was always documented. | ||

| ==== GUI ==== | ==== GUI ==== | ||
| - | * 5.14: Keyboard shortcut for //Download// command in Explorer interface changed to ''Ctrl+T'' (''Ctrl+C'' previously). | + | * 6.2: Drives hidden by Explorer's ''NoDrives'' policy can now be browsed (the same way it is possible in Explorer). Since 6.4, it is be possible to counter that by optionally following ''NoViewOnDrive'' policy. [[bug>2216]] [[bug>2310]] |
| - | * 5.14: Keyboard shortcut for //Open Terminal// command changed to ''Shift+Ctrl+T'' (''Ctrl+T'' previously). | + | |
| - | ==== [[5_14_automation]] Scripting and .NET Assembly ==== | + | ==== .NET Assembly ==== |
| - | * 5.14: URLs in ''open'' command are not matched against stored site name after stripping a protocol. Historically a command like ''%%open sftp://site/%%'' still made WinSCP use stored site ''site'', instead of connecting to host ''site'' using SFTP protocol. Now WinSCP uses stored site only with ''open site''. [[bug>1647]] | + | * 6.2.2: .NET assembly collections are tagged with ''ClassInterfaceType.None'' to avoid warnings from ''regasm''. |
| - | * 5.14: .NET Assembly now targets .NET Framework 4.0. | + | |

| + | * 6.0: Keyboard shortcut for //Command Line// command changed to ''Shift+Ctrl+M'' (''Shift+Ctrl+N'' previously). | ||
| + | * 5.20: Removed support for SSH-1. This should not have any impact, as SSH-1 is not used anymore. | ||
| + | * 5.20: SHA-256 fingerprints are not padded with ''='' anymore. That includes result of .NET assembly ''Session.ScanFingerprint''. WinSCP can still accept padded fingerprints. But new unpadded fingerprints cannot be used with old versions of WinSCP. | ||
| + | * 5.18: Installer needs Windows 7 SP1/2008 R2 SP1. WinSCP application itself still runs on Microsoft Windows XP SP2/Windows Server 2003 SP1 and newer. Use //Portable executables// download. | ||
| + | * 5.16: Consider size of linked file when transferring/synchronizing symbolic link. [[bug>1747]] | ||
| + | * 5.12: When uploading files, ''GetFileAttributes'' is newly used to retrieve file attributes, instead of previous ''FindFirstFile''. With some rare networked drives with broken API, this may cause problems. [[bug>1918]] | ||

| + | * 5.10: All ''5.1*'' versions of WinSCP are incorrectly identified as buggy by OpenSSH 6.9 through 7.4, what may cause connection problems. See [[https://bugzilla.mindrot.org/show_bug.cgi?id=2748|OpenSSH Bug #2748]]. | ||
