Version 4.6.0
(26 May, 2014)
  • Set the server supplied long name in SFTP as the raw string in FTPFile rather than constructing it.

  • Improved performance of binary input streams. Implement skip(), mark() and reset() for FTPInputStream and SSHFTPInputStream.
  • Catch tryLock() exceptions and ignore them. Add flag to avoid using tryLock().
  • Fixed setRemotePort order bug for SFTP. If setRemotePort was called before setProtocol(Protocol.SFTP) then the port was reset to 22.

(13 February, 2012)
  • Added resumeNextDownload(long) to SSHFTPClient, SSLFTPClient and FTPClient so that partial downloads can be done.
  • Added isControlSecure() method to SSLFTPClient to determine if the control connection is secure.

(30 November, 2011)
  • Added support for zlib@openssh.com compression (delayed compression).
  • Algorithm settings for SSH now apply only for the particular SSHFTPClient or SecureFileTransferClient instance that they are set on (previously were static properties). WARNING: if you are using the enable/disable methods on SSHFTPAlgorithm explicitly, this is a breaking change!
  • Added support for FTPS servers that require logging in prior to PBSZ/PROT.
  • Added 'type' command to the script engine.
  • Apply timeout to getting a connection from the connection pool.
  • Deprecated SSLFTPClient constructors now use a non-zero default timeout (which is the same as the default constructor timeout).
  • Add setCheckDirReadableForChDir() to SSHFTPClient.
  • Fix so that IBM JVMs support AES encrypted private keys.

  • Added support for GeneralizedTime in ASN.1 certificate parsing (fixes "Not a UTC_TIME" exception).
  • Fixed integer overflow problem in file upload when the SSH remote window size is greater than MAX_INT.
  • Made local channel counter static so channel number doesn't restart at 0.
  • Change obfuscator (now Proguard), and changed obfuscation so that obfuscated class names are different independent of case (as having two names that are the same other than case doesn't work in JBoss, which is buggy)
Version 3.8.1
(24 May, 2011)
  • Added support for using ACCT in SecureFileTransferClient and FileTransferClient.
  • SSHFTPClient.delete() now throws an exception if a directory is supplied.

(7 April 2011)
  • Added support for AES encrypted private keys (would receive an error message like 'Algorithm AES-128-CBC not recognized' previously).
  • Added support for multiple AVAs of each type in SSL/TLS certificates. Resolves exception thrown parsing certificates "Multiple AVAs found in an RDN".
  • SFTP parallel mode fix to eliminate locking.
  • importDefaultKeyStore() now uses "javax.net.ssl.trustStore" property to locate the key store, and if not found tries lib/security/jssecerts and then lib/security/cacerts.
  • FTPFile.getPath() should not include the filename, only the directory, for all protocols. This includes FTPFile objects returned from dirDetails() and fileDetails().
  • Fixed bug in MLST parser. FTPFile path no longer includes the filename to make consistent with dirDetails().
  • If MLST not supported fileDetails() now falls back to SIZE and MDTM.

  • Don't throw an exception if SSH_MSG_IGNORE message body fails to be parsed.
Version 3.1.1
(8 September, 2009)
  • Remove state checks in signature classes (state should be updated and checked in java.security.Signature, and it appears that on some IBM JVMs, the state variable is not correctly updated). If state checks are removed in subclasses it all works fine.

  • Tweaks to retry functionality.
Version 2.1.2
(25 November, 2008)

  • Fixed SFTP problem where client was hanging transfering a file to WinSSHD. This was due to the client trying to send more data than was available in the server's data window. If the server increased the window but it was still less than the size of the data block, the client hung.
  • Fixed problem where server replies had embedded \r chars. This meant it was wrongly thought that the reply was complete, when in fact more was to come (resulting in out of order replies further along).
