Thanks a lot for tintinweb's contributions.
- bugfix: sftp-put may send the garbage data in some rare case.
- bugfix: fixed a deadlock bug in KnownHosts#getHostKey().
- bugfix: SftpProgressMonitor#init() was not invoked in sftp-put
by using the output-stream.
- change: KnownHosts#setKnownHosts() should accept the non-existing file.
- change: excluding the user interaction time from the timeout value.
- change: addressing SFTP slow file transfer speed with Titan FTP.
- change: updating copyright messages; 2015 -> 2016
Changes since version 0.1.52:

- change: Logjam: use ecdh-sha2-nistp* if available,
ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,
diffie-hellman-group14-sha1,
diffie-hellman-group-exchange-sha256,
diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1
- change: Logjam: diffie-hellman-group-exchange-sha256 and
diffie-hellman-group-exchange-sha1 will use 2048-bit key on
Java8's SunJCE, thanks to JDK-6521495 and JDK-7044060.
- change: key words for OpenSSH's config file should be case-insensitive.
- change: there should be the host name in "WARNING: REMOTE HOST
IDENTIFICATION HAS CHANGED" message.
Changes since version 0.1.51:
- bugfix: resource leak: duplicate keys in LocalIdentityRepository.
- feature: added the support for SSH ECC defined in RFC5656,
ecdsa-sha2-nistp256,
ecdsa-sha2-nistp384,
ecdsa-sha2-nistp521,
ecdh-sha2-nistp256,
ecdh-sha2-nistp384,
ecdh-sha2-nistp521
This functionality requires Java7 or later.
- feature: added the support for server host keys in
ecdsa-sha2-nistp256,
ecdsa-sha2-nistp384,
ecdsa-sha2-nistp521
- feature: generating key-pairs in
ecdh-sha2-nistp256,
ecdh-sha2-nistp384,
ecdh-sha2-nistp521
- change: aes192-ctr, aes256-ctr and
diffie-hellman-group-exchange-sha256 have been enabled
by the default.
- change: key exchange methods, ecdh-sha2-nistp256,
ecdh-sha2-nistp384 and ecdh-sha2-nistp521 have been enabled
by the default.
- change: the support for host keys in ecdsa-sha2-nistp256,
ecdsa-sha2-nistp384 and ecdsa-sha2-nistp521 have been enabled
by the default.
- change: 'examples/KeyGen.java' demonstrates how to generate
ecdsa-sha2-* key-pairs.
- change: updating copyright messages; 2014 -> 2015
- TODO: The ECC support is not functional on Java6 with BouncyCastle.
Changes since version 0.1.50:
- bugfix: reproducibility of "verify: false". FIXED.
Hundreds of thousands of connections had caused that exception.
- bugfix: resource leaks at the failure of making local port forwarding. FIXED.
- bugfix: NPE in connecting to the non-standard TCP port. FIXED.
This problem had appeared if a host-key does not exist in
"known_host" file.
- bugfix: TCP connection may not be dropped if error messages from
the remote are too long. FIXED.
- bugfix: SftpATTRS#getAtimeString() returns the wrong string. FIXED.
- bugfix: bytes to be added by SSH_MSG_CHANNEL_WINDOW_ADJUST must be in
unsigned integer. FIXED.
- bugfix: Util#checkTilde() should not convert a tilde in
"C:\PROGRA~1\". FIXED.
- bugfix: A long long command for ChannelExec will cause
an ArrayIndexOutOfBoundsException. FIXED.
- bugfix: ChannelSftp should not send bulk request greedily even if the remote
window has the enough space. FIXED.
- bugfix: Util.createSocket() should throw an exception with 'cause'. FIXED.
- bugfix: failed to parse .ssh/config in the EBCDIC environment. FIXED.
- bugfix: com.jcraft.jsch.jcraft.HMACSHA1(used only for MacOSX) is not
reusable. FIXED.
- bugfix: NPE caused by the delayed response for channel opening
requests. FIXED.
- bugfix: hung-up in uploading huge data to ProFTPd without the config
'SFTPClientMatch "JSCH.*" channelWindowSize 1GB' FIXED.
- bugfix: Cipher#init() may cause an infinite loop with 100% cpu use due to
https://bugs.openjdk.java.net/browse/JDK-8028627 FIXED.
- bugfix: in some case, JSche#setKnowHosts(InputStream stream) may fail
to close the given stream. FIXED
- change: com.jcraft.jsch.jcraft.HMAC* will not be used.
It seems Java6 on Mac OS X has fixed some memory leak bug in JCE,
so there is no reason to use c.j.j.j.HMAC* introduced at 0.1.30.
- change: updating copyright messages; 2013 -> 2014
- change: allowed to create the symbolic/hard link to the relative path by
ChannelSftp#symlink(String oldpath, String newpath)
ChannelSftp#hardlink(String oldpath, String newpath)
- change: the availability of ciphers listed in "CheckCiphers" config will
not be checked if they are not used.
- change: Util#fromBase64() will throw JSchException in stead of
RuntimeException, if the given string is not in base64 format.
- feature: added the support for private keys in PKCS#8 format.

the implementation of Password-Based Key Derivation Function,
and added its implementation com.jcraft.jsch.jce.PBKDF by using JCE.
Changes since version 0.1.49:
- bugfix: "verify: false" error on Java7u6(and later). FIXED.
http://stackoverflow.com/questions/12279836/ssh-using-jschexception-verify-false-sometimes-fails
https://issues.apache.org/jira/browse/IVY-1374
- bugfix: Session#setPortForwardingL(String bind_address,
int lport, String host, int rport)
will not work for the long host name. FIXED.
- change: changed JSch#getIdentityRepository() to be public.
- feature: added the following method to choose a canceled remote
port-forwarding with the specified bind address,
Session#delPortForwardingR(String bind_address, int rport)
- feature: added support for following OpenSSH's sftp extensions,
and some methods and a class to use those functionalities,
ChannelSftp#hardlink(String oldpath, String newpath),
ChannelSftp#statVFS(String path)
SftpStatVFS
- feature: added support for OpenSSH's configuration file,
JSch#setConfigRepository(ConfigRepository configRepository)
JSch#getConfigRepository()
OpenSSHConfig class
Session#getSession(String host)
and added an example to demonstrate how to use it,
examples/OpenSSHConfig.java
OpenSSHConfig class will recognize the following keywords,
Host
User
Hostname
Port
PreferredAuthentications
IdentityFile
NumberOfPasswordPrompts
