| ====== Incompatible Changes Between Versions ====== | ====== Incompatible Changes Between Versions ====== | ||
| - | This is a summary of rare incompatible changes between versions of WinSCP. With some changes, possible remedies are included. | + | This is a summary of rare incompatible changes between versions of WinSCP, since 5.0 (August 2011). |
| - | ===== General ===== | + | With some changes, possible remedies are included. |
| + | The changes that most commonly causes issues are **highlighted**. | ||
| + | |||
| + | ===== In the Last Major Release 6.2/6.3 (after October 2023) ===== | ||
| + | |||
| + | ==== General ==== | ||
| + | |||
| + | * 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. | ||
| + | |||
| + | ==== .NET Assembly ==== | ||
| + | |||
| + | * 6.2.2: .NET assembly collections are tagged with ''ClassInterfaceType.None'' to avoid warnings from ''regasm''. | ||
| + | |||
| + | ===== In Older Releases (August 2011 -- October 2023) ===== | ||
| + | |||
| + | ==== [[older_general]] General ==== | ||
| + | |||
| + | * 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]] | ||
| + | * 5.12: Last access time of downloaded files is no longer preserved. Note that //modification// time is still preserved. | ||
| * 5.10: Invalid [[file_mask#size_time|size constraints in file mask]] will now fail the operation. Previously, invalid size constraints were ignored. | * 5.10: Invalid [[file_mask#size_time|size constraints in file mask]] will now fail the operation. Previously, invalid size constraints were ignored. | ||
| + | * 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]]. | ||
| * 5.9.3: Not updating last access time of uploaded files with SFTP protocol to avoid problems with servers that do not support it. Previously last access time was updated. [[bug>1485]] | * 5.9.3: Not updating last access time of uploaded files with SFTP protocol to avoid problems with servers that do not support it. Previously last access time was updated. [[bug>1485]] | ||
| * 5.8.3: By default, warning is issued when using Diffie-Hellman group 1 [[ui_login_kex|key exchange algorithm]]. If you need this key exchange algorithm, in scripting use ''open ... -rawsetting KEX=ecdh,dh-gex-sha1,dh-group14-sha1,rsa,dh-group1-sha1,WARN'', in .NET assembly use ''%%SessionOptions.AddRawSettings("KEX", "ecdh,dh-gex-sha1,dh-group14-sha1,rsa,dh-group1-sha1,WARN")%%''. See [[rawsettings|raw site settings]]. | * 5.8.3: By default, warning is issued when using Diffie-Hellman group 1 [[ui_login_kex|key exchange algorithm]].

See [[rawsettings|raw site settings]]. | ||
| * 5.8.3: Fallback between [[ui_login_ssh#protocol_options|SSH versions]] is not supported anymore. This should not have any impact, as SSH-1 is not used anymore. | * 5.8.3: Fallback between [[ui_login_ssh#protocol_options|SSH versions]] is not supported anymore. This should not have any impact, as SSH-1 is not used anymore. | ||
| * 5.8.3: Port number is considered for site-specific caches and bookmarks. You will lose bookmarks for sites that use a non-standard port number. [[bug>1411]] | * 5.8.3: Port number is considered for site-specific caches and bookmarks. You will lose bookmarks for sites that use a non-standard port number. [[bug>1411]] | ||
| - | * 5.8: Using UTF-8 for strings (such as password) with SSH protocol. If your %%SSH%% password contains non-%%ASCII%% characters, and you were able to connect with previous versions of WinSCP, it means that your server does not comply with SSH specification (as older versions of WinSCP did not). You will not be able to login with the new version of WinSCP. Change your password to ASCII characters only as a workaround. [[bug>1014]] | + | * **5.8:** Using UTF-8 for strings (such as password) with SSH protocol. If your %%SSH%% password contains non-ASCII characters, and you were able to connect with previous versions of WinSCP, it means that your server does not comply with SSH specification (as older versions of WinSCP did not). You will not be able to login with the new version of WinSCP. Change your password to %%ASCII%% characters only as a workaround. [[bug>1014]] |
| + | * 5.6.4: Considering directories to have zero size, when matching [[file_mask#size_time|file masks]] or sorting by size, even when the server reports size for the directory, to achieve consistent behavior. | ||
| + | * **5.2.5:** Using UTF-8 for strings (such as file names) with SFTP protocol by default even for version 3 and lower. If your server does not use %%UTF-8%%, you can revert to the previous behavior by setting the //[[ui_login_environment#utf|UTF-8 encoding for filenames]]// to //Off//. [[bug>1072]] | ||
| + | * 5.2: Dropped support for Windows 2000. Minimal supported version is Windows XP. | ||
| + | * 5.0.7: Dropped support for Windows 95/98/ME. | ||
| + | * 5.0.7: Blowfish is preferred [[ui_login_ssh|SSH encryption cipher]]. [[bug>1]] | ||
| + | * 5.0.6: File mask that does not end with slash matches only files, not directories anymore. | ||
| + | * 5.0.6: Include directory masks are recursive. | ||
| + | * 5.0.6: Include file mask that does not contain any directory mask matches any directory. | ||
| + | * 5.0.6: Special characters '';,|<>'' in file masks can be used as literals by doubling them. | ||
| + | * 5.0.2: Binary [[transfer_mode|transfer mode]] is default. [[bug>670]] | ||
| + | * 5.0.2: With FTP protocol, [[ftp_modes|passive mode]] is used by default. [[bug>165]] | ||
| - | ===== GUI ===== | + | ==== GUI ==== |
| + | * 5.20: Keyboard shortcut for //Restore Selection// command changed to ''Shift+Ctrl+S'' (''Shift+Ctrl+R'' previously). | ||
| + | * 5.20: Monitoring ''A:'' and ''B:'' drives. | ||
| + | * 5.16: Removed option to create //Quick Launch// icons (Windows Vista and older only). | ||
| + | * 5.14: Keyboard shortcut for //Download// command in Explorer interface changed to ''Ctrl+T'' (''Ctrl+C'' previously). | ||
| + | * 5.14: Keyboard shortcut for //Open Terminal// command changed to ''Shift+Ctrl+T'' (''Ctrl+T'' previously). | ||
| * 5.8.2: Remote custom commands cannot be executed with focus on local panel. Make sure you have the remote panel focused, when executing a remote custom command. | * 5.8.2: Remote custom commands cannot be executed with focus on local panel. Make sure you have the remote panel focused, when executing a remote custom command. | ||
| * 5.8: Interface theme is not configurable anymore. Only single theme is supported. | * 5.8: Interface theme is not configurable anymore. Only single theme is supported. | ||
| * 5.8: Change of language on run-time is not supported anymore. | * 5.8: Change of language on run-time is not supported anymore. | ||
| * 5.8: Shortcut of command //Clear Selection// changed to ''Shift+Ctrl+L''. | * 5.8: Shortcut of command //Clear Selection// changed to ''Shift+Ctrl+L''. | ||
| + | * 5.2: Session from command-line and/or from jump list is opened by default using existing WinSCP instance. To revert to the previous behavior, use the //[[ui_pref_window|Open new externally initiated sessions in existing window]]//. [[bug>769]] | ||
| + | * 5.0.6: //Include/Exclude mask// in transfer settings replaced with //File mask//, what is equivalent of //Include mask// (as supported already previously, it can contain exclude mask after ''|''). | ||
| + | * 5.0.6: Session option //Remember last used directory// is enabled by default. | ||
| + | * 5.0.3: Synchronized browsing state is stored with stored session, not in preferences. [[bug>10]] | ||
| + | * 5.0.3: In mouse-only [[ui_pref_commander|Explorer-style selection mode]], single-file implicit mouse-selection is not preserved, when focus/selection is subsequently changed using keyboard. | ||
| - | ===== Scripting and .NET Assembly ===== | + | ==== Installer ==== |
| - | * 5.10: When executing script file or script commands provided on command-line, default reconnect time is set to 120 seconds, if not limited yet by configuration. Previously, WinSCP tried to reconnect indefinitely by default. To force back the previous behavior, in scripting use ''option reconnecttime 0'', in .NET assembly use ''Session.ReconnectTime = TimeSpan.MaxValue''. | + | * 5.16: Silent installation needs additional ''/ALLUSERS'' or ''/CURRENTUSER'' switches. |
| - | * 5.10: Change: Deprecating ''Session.DisableVersionCheck''. Always use the same version of WinSCP and WinSCP .NET assembly. | + | * 5.16: Installer does not support Windows XP/2003 anymore. WinSCP application itself still runs on Windows XP/2003. Use //Portable executables// download. |
| + | * 5.17.6: Installer does not support Windows Vista/2008 anymore. WinSCP application itself still runs on Windows Vista/2008. Use //Portable executables// download. | ||
| + | |||
| + | ==== [[older_automation]] Scripting and .NET Assembly ==== | ||
| + | |||
| + | * 6.0.1: ''SessionOptions.WebdavSecure'' renamed to ''SessionOptions.Secure'' (and applies to S3 protocol too). | ||
| + | * 5.18: Deprecated [[library_sessionoptions#giveupsecurityandacceptanysshhostkey|''SessionOptions.GiveUpSecurityAndAcceptAnySshHostKey'']] in favour of [[library_sessionoptions#sshhostkeypolicy|''SshHostKeyPolicy.GiveUpSecurityAndAcceptAny'']]. | ||
| + | * 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. | ||
| + | * 5.17.3: ''SHA-1'' fingerprint of TLS/SSL certificate was incorrectly presented as ''MD5'' by ''Session.ScanFingerprint''. | ||
| + | * 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]] | ||
| + | * 5.14: .NET Assembly now targets .NET Framework 4.0. | ||
| + | * 5.12: XML log tags ''<modification>'' and ''<permisssions>'' are absent, if their values are not known. Previously they would have value of ''1899-12-30T01:00:00.000Z'' and ''---------'' respectively. Consequently the .NET assembly ''RemoteFileInfo.LastWriteTime'' and ''RemoteFileInfo.FilePermissions'' have values ''DateTime.MinValue'' and ''null'', respectively. | ||
| + | * 5.12: Scripting command ''mv'' and .NET assembly function ''Session.MoveFile'' tests, if a source file exists, before trying to rename. Consequently, an error message reported has changed significantly, if the source file does not exist. | ||
| + | * 5.12.1: .NET assembly instance methods ''Session.EscapeFileMask'', ''Session.CombinePaths'', ''Session.TranslateLocalPathToRemote'' and ''Session.TranslateRemotePathToLocal'' replaced by static methods of the same name in class ''RemotePath''. | ||
| + | * 5.12.1: ''Session.ScanFingerprint'' has a new mandatory ''algorithm'' parameter. To keep the previous behavior use ''%%MD5%%'' as a parameter value (though for new development, use ''%%SHA-256%%''). | ||
| + | ··* 5.10: When executing script file or script commands provided on command-line, default reconnect time is set to 120 seconds, if not limited yet by configuration. Previously, WinSCP tried to reconnect indefinitely by default. To revert to the previous behavior, in scripting use ''option reconnecttime 0'', in .NET assembly use ''Session.ReconnectTime = TimeSpan.MaxValue''. | ||
| + | * 5.10: XML log EOL has changed from LF to CRLF. | ||
| * 5.9.1: ''[[library_session_enumerateremotefiles|Session.EnumerateRemoteFiles]]'' does not throw when reading subdirectory fails. To capture errors, use the ''[[library_session_failed|Session.Failed]]'' event. | * 5.9.1: ''[[library_session_enumerateremotefiles|Session.EnumerateRemoteFiles]]'' does not throw when reading subdirectory fails. To capture errors, use the ''[[library_session_failed|Session.Failed]]'' event. | ||
| * 5.8.3: A complete remote error message is stored into a single instance of ''SessionRemoteException'', instead of separating error details into an inner exception. This should have any impact only, if your code checks for specific error message in inner exception. This is not recommended though. | * 5.8.3: A complete remote error message is stored into a single instance of ''SessionRemoteException'', instead of separating error details into an inner exception. This should have any impact only, if your code checks for specific error message in inner exception. This is not recommended though. | ||
| * 5.8.1: Deprecating ''Session.IniFilePath'' in favor of ''[[library_session_addrawconfiguration|Session.AddRawConfiguration]]''. You can [[ui_generateurl#code|generate a code template]] with the ''AddRawConfiguration'' calls. | * 5.8.1: Deprecating ''Session.IniFilePath'' in favor of ''[[library_session_addrawconfiguration|Session.AddRawConfiguration]]''. You can [[ui_generateurl#code|generate a code template]] with the ''AddRawConfiguration'' calls. | ||
| - | * 5.8: [[scripting#using_scripting|Script file]] has to be in UTF-8 encoding. This matter only if you use non-ASCII characters in filenames and/or credentials. | + | * **5.8:** [[scripting#using_scripting|Script file]] has to be in UTF-8 encoding. This matter only if you use non-ASCII characters in filenames and/or credentials. If you are you will get error message [[message_no_mapping_for_unicode|No mapping for the Unicode character exists in the target multi-byte code page -- The file must be in UTF-8 or UTF-16 encoding]]. |
| * 5.8. The ''[[library_remotefileinfo#name|RemoteFileInfo.Name]]'' now contains a name only, even for a ''RemoteFileInfo'' instance returned by the ''[[library_session_getfileinfo|Session.GetFileInfo]]''. | * 5.8. The ''[[library_remotefileinfo#name|RemoteFileInfo.Name]]'' now contains a name only, even for a ''RemoteFileInfo'' instance returned by the ''[[library_session_getfileinfo|Session.GetFileInfo]]''. | ||
| * 5.8: Deprecating ''Session.DefaultConfiguration in'' favor of ''[[library_session_addrawconfiguration|Session.AddRawConfiguration]]''. You can [[ui_generateurl#code|generate a code template]] with the ''AddRawConfiguration'' calls. | * 5.8: Deprecating ''Session.DefaultConfiguration in'' favor of ''[[library_session_addrawconfiguration|Session.AddRawConfiguration]]''. You can [[ui_generateurl#code|generate a code template]] with the ''AddRawConfiguration'' calls. | ||
| - | * 5.8: ''SessionOptions.SshPrivateKeyPassphrase'' renamed to ''[[library_sessionoptions#privatekeypassphrase|SessionOptions.PrivateKeyPassphrase]]''. | + | * **5.8:** ''SessionOptions.SshPrivateKeyPassphrase'' renamed to ''[[library_sessionoptions#privatekeypassphrase|SessionOptions.PrivateKeyPassphrase]]''. |
| + | * 5.6.5: ''[[library_session_calculatefilechecksum|Session.CalculateFileChecksum]]'' method returns a byte array instead of a string to match .NET framework cryptography functions. | ||
| + | * 5.6.3: ''[[scriptcommand_lls|lls]]'' by default only displays a notification that no matching file is found, instead of failing. | ||
| + | * **5.6.2:** A .NET assembly method ''[[library_session_executecommand|Session.ExecuteCommand]]'' does not throw an exception on error. Instead a ''CommandExecutionResult'' now descends from a ''OperationResultBase''. Use the ''[[library_operationresultbase#check|OperationResultBase.Check]]'' method to reproduce the previous behavior. | ||
| + | * **5.6:** When executing script file or script commands provided on command-line, default [[scriptcommand_option#batch|batch mode]] is ''abort'' and [[scriptcommand_option#confirm|confirmations]] are turned off. Use ''option batch off'' and ''option confirm on'' at the beginning of your script to revert to the previous defaults. Though the new defaults were always recommended values to be used in the scripts. | ||
| + | * 5.6: Enabling batch mode in scripting automatically limits reconnect time to 120 seconds, if it is not limited yet. To revert to the previous behavior, in scripting use ''option reconnecttime 0'', in .NET assembly use ''Session.ReconnectTime = TimeSpan.MaxValue''. [[bug>1173]] | ||
| + | * 5.6: When host key does not match fingerprint specified on command line or in script, user is not prompted to verify the host key and connection is abandoned with meaningful error message. [[bug>1186]] | ||
| + | * 5.2.5: ==Semicolon== symbol '';'' has special meaning in [[session_url|session URL]] and has to be [[session_url#special|URL-encoded]] to ''%3B'', when used as a literal. | ||
| + | * 5.2.5: UTF-8 encoded characters in [[session_url|session URL]] are supported. If you were using non-ASCII URL-encoded characters in the session URL, you need to [[session_url#special|re-code them to UTF-8]]. [[bug>1062]] | ||
| + | * **5.2.3:** In .NET assembly, ''[[library_sessionoptions|SessionOptions]]'' class properties ''SslHostCertificateFingerprint'' and ''GiveUpSecurityAndAcceptAnySslHostCertificate'' renamed to ''[[library_sessionoptions#tlshostcertificatefingerprint|TlsHostCertificateFingerprint]]'' and ''[[library_sessionoptions#giveupsecurityandacceptanytlshostcertificate|GiveUpSecurityAndAcceptAnyTlsHostCertificate]]'', respectively. | ||
| + | * **5.0.9:** In .NET assembly ''[[library_sessionoptions|SessionOptions]]'' class property ''SshHostKey'' renamed to ''[[library_sessionoptions#sshhostkeyfingerprint|SshHostKeyFingerprint]]'', ''SshPrivateKey'' to ''[[library_sessionoptions#sshprivatekeypath|SshPrivateKeyPath]]'' and ''SslCertificate'' to ''SslHostCertificateFingerprint'' (and later to ''[[library_sessionoptions#tlshostcertificatefingerprint|TlsHostCertificateFingerprint]]''). | ||
| + | * 5.0.8: Scripting command ''[[scriptcommand_rm|rm]]'' and .NET assembly ''[[library_session_removefiles|Session.RemoveFiles]]'' method can remove directories as well. [[bug>887]] | ||
| + | * 5.0.6: Script options ''exclude'' and ''include'' deprecated in favor of ''-filemask=<mask>'' switch of ''get'', ''put'', ''synchronize'' and ''keepuptodate'' commands. | ||
| + | * 5.0.6: Script option ''transfer'' deprecated in favor of ''-transfer'' switch of ''get'', ''put'', ''synchronize'' and ''keepuptodate'' commands. | ||
| + | * 5.0.6: Escaping new lines in attribute values in XML log (particularly useful for attribute ''value'' of ''output'' and ''erroroutput''). | ||
| + | * 5.0.3: All fatal errors (those that cause exit code of WinSCP to be 1) in scripting are recorded in new subtag ''failure'' of root tag ''session'' in [[logging_xml|XML log]]. This includes connection errors, replacing previous recording in ''result'' tag. | ||
| + | * 5.0.3: Value ''both'' of ''[[scriptcommand_synchronize|synchronize]]'' command switch ''criteria'' renamed to ''either'' to avoid confusion (''both'' is still recognized for backward compatibility). [[bug>195]] | ||
| + | * 5.0.3: Silently ignoring, when local file mask in ''[[scriptcommand_put|put]]'' command matches no file. To revert to the previous behavior, use the ''[[scriptcommand_option#failonnomatch|option failonnomatch on]]'' before the ''put'' command. [[bug>746]] | ||
| + | * 5.0.2: Connection error is recorded in XML log in new subtag ''result'' of root tag ''session''. [[bug>545]] | ||
