Portable SecureCRT full changelog

Vulnerabilities addressed:
When certain emulation functions received a large negative number as a parameter, it could have allowed the remote system to corrupt memory in the terminal process, potentially causing the execution of arbitrary code or a crash.

New feature:
- Windows: Added an administrative policy that disallows the TFTP
server from being run.

Change:
SSH2: Keyboard-interactive authentication works with a prompt that contains "password" with any combination of upper and lower case letters (e.g., "Password" or "PASSWORD").
Bug fixes:
When an editor (e.g., vi or vim) was used to edit a file on the remote system, the wrong line could have been deleted when the delete line command was sent.
When a session with an authentication banner reconnected, extra newlines were inserted after the banner.
Windows: Sending a session to a new window and then attempting to lock it with the "Hide Output" option checked resulted in a crash.
Windows: If the global transparency setting for active sessions was set to a value less than 255, when a tabbed session was cloned, no output was displayed.

Changes:
Updated the version of Python that ships with SecureCRT to 2.7.16.
Bug Fixes:
Windows: When using both the left and right mouse buttons to simulate a middle-button click, and the "Paste on middle button" option was enabled, the paste operation would not succeed.

Change:
Treat the curve25519-sha256@libssh.org key-exchange algorithm as
Synonymous to the curve25519-sha256 algorithm.

New feature:
Added a new script function FileSaveDialog() that allows saving to
a file that does not exist.
Bug fixes:
If the command line specified a saved session (/S) and overrode the
local listening IP address (/LOCAL), an error was reported and the
session did not connect.
The button bar list was empty if button bars were imported when the
button bar list was not displayed and then the button bar was
displayed.
Windows: On Windows Server 2008 R2, the icons in the Session Manager
and Connect dialog were not drawn correctly.
Windows: On a high-DPI monitor scaled to 125%, the 10-point Lucida
Console font looked larger and bold compared to how that font looked
in other applications.

Bug fix:
When the script recorder was used to generate a Python script, escape characters [chr(92)] were not included in the script.

SecureCRT 8.3 enhances the user interface with built-in
Solarized and other ANSI color schemes and line rewrapping when
the SecureCRT window is resized. Save time with a new Connect
bar auto complete and the ability to drag and drop multiple
sessions in the Session Manager and Connect dialog. A paste
confirmation dialog option helps prevent accidental pastes of
multiple lines of text. Also new is support for ChaCha20/Poly
1305, AES-GCM, and OpenSSH certificates.

Changes:
Added default key mappings to Xterm emulation for CTRL+HOME, CTRL+END, CTRL+SHIFT+END, CTRL+SHIFT+HOME, SHIFT+HOME, SHIFT+END, SHIFT+PGUP, and SHIFT+PGDN.
Bug fixes:
SecureCRT crashed if the pre-defined color scheme "Solarized Light" was deleted.
If a dialog was displayed while attempting to open a log file when connecting to a session and the session attempted to automatically reconnect before the dialog was dismissed, SecureCRT crashed when the dialog was dismissed.
The performance of scrolling large amounts of data with keyword highlighting and the "Minimize drawing" option set was significantly slower than in version 8.1.
In the multi-line paste dialog, the clipboard text was very small on high-DPI monitors.
Windows: SecureCRT could not be installed on Windows Server 2008.
Windows: If the Connect bar was moved to the menu bar using the
Customize dialog, auto complete in the Connect bar no longer worked.
Windows: Many dialogs had display issues on high-DPI monitors when the
