PuTTY 歷史版本列表
更新時間：2015-02-28
更新細節：
What's new in this version:
- Security fix: PuTTY no longer retains the private half of users' keys in memory by mistake after authenticating with them. See private-key-not-wiped-2. (Sorry! We thought we'd fixed that in 0.63, but missed one.)
- Support for SSH connection sharing, so that multiple instances of PuTTY to the same host can share a single SSH connection instead of all having to log in independently.
- Command-line and configuration option to specify the expected host key(s).
- Defaults change: PuTTY now defaults to SSH-2 only, instead of its previous default of SSH-2 preferred.
- Local socket errors in port-forwarded connections are now recorded in the PuTTY Event Log.
- Bug fix: repeat key exchanges in the middle of an SSH session now never cause an annoying interactive host key prompt.
- Bug fix: reset the bolded-text default setting back to what it used to be. (0.63 set it to something wrong, as a side effect of refactoring.)
- Bug fix: IPv6 literals are handled sensibly throughout the suite, if you enclose them in square brackets to prevent the colons being mistaken for a :port suffix.
- Bug fix: IPv6 dynamic port forwardings should work again.

What's new in this version:
- Security fix: prevent a nefarious SSH server or network attacker from crashing PuTTY at startup in three different ways by presenting a maliciously constructed public key and signature.
- Security fix: PuTTY no longer retains the private half of users' keys in memory by mistake after authenticating with them.
- Revamped the internal configuration storage system to remove all fixed arbitrary limits on string lengths. In particular, there should now no longer be an unreasonably small limit on the number of port forwardings PuTTY can store.
- Port-forwarded TCP connections which close one direction before the other should now be reliably supported, with EOF propagated independently in the two directions. This also fixes some instances of port-forwarding data corruption (if the corruption consisted of losing data from the very end of the connection) and some instances of PuTTY failing to close when the session is over (because it wrongly thought a forwarding channel was still active when it was not).
- The terminal emulation now supports xterm's bracketed paste mode (allowing aware applications to tell the difference between typed and pasted text, so that e.g. editors need not apply inappropriate auto-indent).
- You can now choose to display bold text by both brightening the foreground colour and changing the font, not just one or the other.
- PuTTYgen will now never generate a 2047-bit key when asked for 2048 (or more generally n−1 bits when asked for n).
- Some updates to default settings: PuTTYgen now generates 2048-bit keys by default (rather than 1024), and PuTTY defaults to UTF-8 encoding and 2000 lines of scrollback (rather than ISO 8859-1 and 200).
- Unix: PSCP and PSFTP now preserve the Unix file permissions, on copies in both directions.
- Unix: dead keys and compose-character sequences are now supported.
- Unix: PuTTY and pterm now permit font fallback (where glyphs not present in your selected font are automatically filled in from other fonts on the system) even if you are using a server-side X11 font rather than a Pango client-side one.
- Bug fixes too numerous to list, mostly resulting from running the code through Coverity Scan which spotted an assortment of memory and resource leaks, logic errors, and crashes in various circumstances.

What's new in this version:
- Pressing Ctrl+Break now sends a serial break signal. (The previous behaviour can still be obtained with Ctrl+C.)
- Serial ports higher than COM9 now no longer need a leading \..
- You can now store a host name in the Default Settings.
- Bug fix: serial connections and local proxies should no longer crash all the time.
- Bug fix: configuring the default connection type to serial should no longer cause the configuration dialog to be skipped on startup.
- Bug fix: "Unable to read from standard input" should now not happen, or if it still does it should produce more detailed diagnostics.
- Bug fix: fixed some malformed SSH-2 packet generation.
- Other minor bug fixes.

What's new in this version:
- PuTTY can now connect to local serial ports as well as making network connections.
- Windows PuTTY now supports "local proxying", where a network connection is replaced by a local command. (Unix PuTTY has supported this since it was first released in 0.54.) Also, Plink has gained a "-nc" mode where the primary channel is replaced by an SSH tunnel, which makes it particularly useful as the local command to run.
- Improved speed of SSH on Windows (particularly SSH-2 key exchange and public-key authentication).
- Improved SFTP throughput.
- Various cryptographic improvements in SSH-2, including SDCTR cipher modes, a workaround for a weakness in CBC cipher modes, and Diffie-Hellman group exchange with SHA-256.
- Support for the Arcfour cipher in SSH-2.
- Support for sending terminal modes in SSH.
- When Pageant is running and an SSH key is specified in the configuration, PuTTY will now only try Pageant authentication with that key. This gets round a problem where some servers would only allow a limited number of keys to be offered before disconnecting.
- Support for SSH-2 password expiry mechanisms, and various other improvements and bugfixes in authentication.
- A change to the SSH-2 password camouflage mechanism in 0.58 upset some Cisco servers, so we have reverted to the old method.
- The Windows version now comes with documentation in HTML Help format. (Windows Vista does not support the older WinHelp format. However, we still provide documentation in that format, since Win95 does not support HTML Help.)
- On Windows, when pasting as RTF, attributes of the selection such as colours and formatting are also pasted.
- Ability to configure font quality on Windows (including antialiasing and ClearType).
- The terminal is now restored to a sensible state when reusing a window to restart a session.
- We now support an escape sequence invented by xterm which lets the server clear the scrollback (CSI 3 J). This is useful for applications such as terminal locking programs.
- Improvements to the Unix port:
- now compiles cleanly with GCC 4
- now has a configure script, and should be portable to more platforms
- Bug fix: 0.58 utterly failed to run on some installations of Windows XP.
- Bug fix: PSCP and PSFTP now support large files (greater than 4 gigabytes), provided the underlying operating system does too.
- Bug fix: PSFTP (and PSCP) sometimes ran slowly and consumed lots of CPU when started directly from Windows Explorer.
- Bug fix: font linking (the automatic use of other fonts on the system to provide Unicode characters not present in the selected one) should now work again on Windows, after being broken in 0.58. (However, it unfortunately still won't work for Arabic and other right-to-left text.)
- Bug fix: if the remote server saturated PuTTY with data, PuTTY could become unresponsive.
- Bug fix: certain large clipboard operations could cause PuTTY to crash.
- Bug fix: SSH-1 connections tended to crash, particularly when using port forwarding.
- Bug fix: SSH Tectia Server would reject SSH-2 tunnels from PuTTY due to a malformed request.
- Bug fix: SSH-2 login banner messages were being dropped silently under some circumstances.
- Bug fix: the cursor could end up in the wrong place when a server-side application used the alternate screen.
- Bug fix: on Windows, PuTTY now tries harder to find a suitable place to store its random seed file PUTTY.RND (previously it was tending to end up in C: or C:WINDOWS).
- Bug fix: IPv6 should now work on Windows Vista.
- Numerous other bugfixes, as usual.

What's new in this version:
- Wildcards (mput/mget) and recursive file transfer in PSFTP.
- You can now save your session details from the Change Settings dialog box, after you've started your session.
- Various improvements to Unicode support, including:
+ support for right-to-left and bidirectional text (Arabic, Hebrew etc). Thanks to arabeyes.org for design and most of the implementation.
+ support for Arabic text shaping, again thanks to arabeyes.org.
+ support for Unicode combining characters.
- Support for the xterm 256-colour control sequences.
- Port forwardings can now be reconfigured in mid-session.
- Support for IPv6. Thanks to unfix.org for having patiently maintained the patch for this until we were finally ready to integrate it.
- More configurability and flexibility in SSH-2 key exchange. In particular, PuTTY can now initiate repeat key exchange during the session, which means that if your server doesn't initiate it (some servers don't bother) you can still have the cryptographic benefits.
- Bug fix: display artefacts caused by characters overflowing their character cell should now all be gone. (This would probably have bothered Windows ClearType users more than anyone else.)
- Bug fix: keepalives are now supported everywhere. (Previously they were supported by Windows GUI PuTTY, but were missing in Plink, PSFTP and the Unix port.)
- Miscellaneous improvements for CJK/IME users; many thanks to Hung-Te Lin for assistance.

What's new in this version:
- Security fixes: two vulnerabilities discovered by iDEFENSE, potentially allowing arbitrary code execution on an SFTP client by a malicious SFTP server (but only after host key verification), have been fixed. See vuln-sftp-readdir, vuln-sftp-string.
- Fixed small bug with X forwarding to local displays.
- Fixed crashing bug with remote port forwarding.
- Fixed handling of SSH-2 debug messages (embarrassingly, a bug introduced when fixing the previous vulnerability - it was more secure but didn't work any more!).

What's new in this version:
- Security fix: a vulnerability discovered by iDEFENSE, potentially allowing arbitrary code execution on the client by a malicious SSH-2 server before host key verification, has been fixed. See vuln-ssh2-debug.
- Ability to restart a session within an inactive window, via a new menu option.
- Minimal support for not running a shell or command at all in SSH protocol 2 (equivalent to OpenSSH's "-N" option). PuTTY/Plink still provide a normal window for interaction, and have to be explicitly killed.
- Transparent support for CHAP cryptographic authentication in the SOCKS 5 proxy protocol. (Not in PuTTYtel.)
- More diagnostics in the Event Log, particularly of SSH port forwarding.
- Ability to request setting of environment variables in SSH (protocol 2 only). (However, we don't know of any servers that support this.)
- Ability to send POSIX signals in SSH (protocol 2 only) via the "Special Commands" menu. (Again, we don't know of any servers supporting this.)
- Bug fix: The PuTTY tools now more consistently support usernames containing "@" signs.
- Support for the Polish character set "Mazovia".
- When logging is enabled, the log file is flushed more frequently, so that its contents can be viewed before it is closed.
- More flexibility in SSH packet logging: known passwords and session data can be omitted from the log file. Passwords are omitted by default. (This option isn't perfect for removing sensitive details; you should still review log files before letting them out of your sight.)
- Unix-specific changes:
+ Ability to set environment variables in pterm.
+ PuTTY and pterm attempt to use a UTF-8 line character set by default if this is indicated by the locale; however, this can be overridden.
