RELEASE NOTES



**IMPORTANT**: If this is the first time you have installed VirtualVP, you should read 

the User Guide or at least the Quick Start Guide before trying to connect. Using 

VirtualVP requires that 3rd party freeware drivers be installed on your computer, and 

that VirtualVP be configured to match the configuration of the driver(s) you choose to 

use. 



VirtualVP is distributed as shareware. A fully functional 30 day trial version is 

available so you can try the software and see if it fits your needs. To use the software

past the trial period, look on the website for information on paying to register. The 

cost to register is $30. When notice of payment has been received, you will be sent a 

personal serial number and registration key. There is a form within VirtualVP for 

entering the registration information. Once you are a registered user, you are entitled 

to free updates. You will not be asked to pay to upgrade to new versions. 



I will fix bugs that are reported as quickly as possible. If you encounter a problem, 

before reporting it, check the website for a new version. If there is one, look at the

release notes to see if your problem has already been identified and fixed. 



IMPORTANT: If you send a bug report, attach the following files to your email: 

archiveCache.dat, virtualvp.ini, console.txt, and log.txt 

These files will greatly assist me in determining the problem quickly.



KNOWN BUGS AND ISSUES



Occasionally a very small memory leak of ApdDataPacket will be reported when VirtualVP

closes. This only happens if VirtualVP had to forceably reset a "stuck" socket connection. 

Other memory leaks should be reported.



VERSION HISTORY


v. 1.2.5
Removed EEBRD debugging messages introduced in v. 1.2.4
Changed VER response to alter the reported console version to v. 1.80 for firmware
	versions 2.1x as well (for Vantage Vue consoles).

v. 1.2.4 (limited release)
Changed VER response to alter the reported console version to v. 1.80 so that connected
	software do not use the as yet undocumented (by Davis) commands that were new to
	firmware versions 1.9x.

v. 1.2.3 Dec 6 2009
Fixed bug that prevented operation on 64-bit versions of Windows.
VirtualVP now uses the user data folder (Users\{username}\AppData\Local\SoftWx\VirtualVp)
	for all files to which data is written instead of the VirtualVP installation folder
	in order to function better on Vista and Windows 7 computers.
Made changes so that VirtualVP only needs to be run as administrator once to to enable
	the initial 30 day trial, and when the registration code is entered. The rest of
	the time, VirtualVP can be run in normal user accounts without administrator
	privileges.
Added pictorial instructions for installation and configuration of VirtualVP and weather
	programs that connect through it, and also for setting up a virtual serial port
	driver on 64-bit Windows 7.
Removed option for mirroring archive data to disk. VirtualVP will now always mirror to disk.

v. 1.2.2 Nov 8 2009
Fixed bug in DMPAFT handling (archive download) that started with the archive record for the
	time given, not the record following that, per the Davis spec (dump AFTER the given time)
Added support for the NVER command (firmware version number)
Added code to fix imcompatibility between VirtualVP and WeatherLink, introduced with 
	WeatherLink v. 5.9.0

v. 1.2.1 July 15 2009
Fixed bug causing the about box to show the incorrect registration status


v. 1.2.0 July 13 2009
Added support for connecting to TCP/IP data logger. This feature also allows connecting
on VirtualVP to another, allowing "daisy-chaining".


v. 1.1.4 Beta Nov 24 2006
Fixed bug that sometimes caused virtual ports to not get reopened if console connection
	was lost and then quickly re-established.

v. 1.1.3 Beta Nov 19 2006
Added code that will continue attempting to reconnect to the console after an
	interrupted connection.
Added option to reset the Davis USB driver (in case you have the USB data logger) 
	if the connection is interrupted. This can recover connections lost because
	of driver failure.
Fixed bug in the code that detects broken connections.

v. 1.1.2 Beta Nov 5 2006
You can now double click on the tray icon to show the VirtualVP main window when it's
	minimized to the tray.
Fixed a bug in the shared timer dispatcher code.
Updated support email and website links in the About VirtualVP window.
VirtualVP now remembers the sort order preference for the Alerts page.
Fixed bug in minimeze at startup option (it didn't work at all before).
Fixed memory leak displayed when closed by StartWatch.

v. 1.1.1 Beta Sep 24 2006
Fixed bug where "Protect Console" settings for TCP/IP connections weren't being saved.

v. 1.1.0 Beta Sep 24 2006
 Bug Fixes
Fixed some bugs and inefficencies in the low level timer code.
Fixed bug that caused excessive numbers of registrations reminder message boxes.
 Features
Made the main form use a tabbed display with multiple display pages.
Added the Status display page, and made it the default page. 
Added the Alerts display page. Alerts will be used to display messages that would 
	have been displayed in message boxes in previous versions.
Added blinking red dot in tray icon to indicate there are alerts to read.
Added the date to the time display on the Activity page.
Added Settings menu item to control the update frequency of the Status page. Less 
	frequent updates use less CPU.
Added Settings menu item to turn off animation of the console traffic arrows between the
	console and VirtualVP on the Status page. Turning animation off uses less CPU.
Optimized the code so it releases most windows display resources and skips the display
	update code when the program is minimized to the tray. This reduces the resource
	and CPU footprint of the program while minimized.
Removed the reception display from the status bar. The purpose of VirtualVP is
	communications, not the display of console or weather data. Avoiding expansion
	outside this focus improves the robustness of the program, and will also make 
	the eventual migration of VirtualVP to a Windows service application easier.
Added 4 more virtual console slots. The first four are dedicated to serial communications
	via virtual COM ports, and the second 4 are dedicated to TCP/IP communications.
	This is part of the eventual migration of the TCP/IP communications to a normal
	server architecture where a single port can serve multiple connection requests.
Changed the Communications Settings dialog to support the 4 + 4 virtual console change,
	and also attempted to simplify the dialog. Also added configuration tips.

v. 1.0.3 Apr 30 2006
Fixed bug in virtual console command parameter parsing and forwarding

v. 1.0.2 Apr 16 2006
Extended the trial period from 15 to 30 days
Added an option to control Fast Looping (fast gets loop data every second, normal gets loop data every 2 seconds)

v. 1.0.1 Apr 7 2006
Made improvements to opening and closing of socket connections
Added code to detect some permanent error states in socket connections and restart the connection when that happens
Added menu to main form to allow manually restarting virtual console connections
Fixed a bug in reception percentage calculation when there are no stations connected to the console
Fixed a bug that allowed redundant commands to get queued up when the console is being particularly slow to respond
The time period used for the displayed reception was 1 minute instead of the 2 minutes stated in the manual. 
	It's now 2 minutes.
Fixed bug in shared timer that sometimes prevented the very first timer set from firing (i.e. the splash box would 
	stay up)
Fixed bug that didn't include the virtual console name in log entries if the console was connected via TCP
The log.txt error log will now include warnings as well
Added code to clear the error log file when it reaches 250Kb in size to prevent it from growing forever
Changed the defualt configuration to use virtual COM ports COM16 to COM19 instead of COM11 to COM14
Removed the code in the Communications Settings dialog that checked which COM ports were available (dialog opens 
	faster now)
Added new feature that lets you direct a virtual console to protect the console from changes by not passing on 
	commands that would change or clear data within the console
Added code to get the VP console's internal settings and write them to a console.txt file 
Added code to periodically analyze and repair the archive mirror to help insure it is consistant and matches the 
	console's archive
Fixed a bug related to COM port flow control settings
Fixed a bug that prevent NACK responses from the console from be propagated back to the client weather program

v. 1.0.0 Mar 12 2006 
Added User Guide and menu item under Help for opening the Guide
Added Release Notes menu item under Help for opening the Release Notes
Reorganized the Communications Settings dialog
Fixed bug that caused infinite retries when a connection to the console was successfully made, but nothing on 
	the other end responds
Added Connection status icon to status bar
Added Reception information to the status bar
Now use hardware flow control options on serial port connections to be compatible with some virtual port drivers

v. 0.2.3 Release Candidate 1
Added ability for Virtual consoles to accept TCP/IP connections in addition to COM port serial connections
Added ability to disable unneeded virtual consoles (saves resources)
Added ability to auto-create virtual com ports using HW_VSP, with VirtualVP handling the creation and configuration 
	of the HW_VSP ports
Renamed the COM Port settings dialog to Communication settings, and rewrote it to support new connection features
Reduced potential for missed sensor data (>2.5 seconds between Loop packets) when commands are sent to the console 
	that take a long time to complete
The main form and the activity window now remember and open at their last position and size
If the screen resolution has been reduced since the last time VirtualVP was run, and the last position of the window 
	is now off-screen, the form will move itself into view
Dialogs that open centered on the main window will make sure no part of the dialog runs off the screen, and will 
	adjust their position so they are fully visible if neccessary
Improved Connect and Disconnect failure messages
Fixed bug that sometimes would cause the virtual consoles to stop responding if there was a long period of inactivity
Double clicking on the message in the status bar now clears the message
Fixed minor resource leak (wasn't releasing tray icons on program close)

v. 0.2.2 Beta 
Added software registration
Made further improvements to communication timing and command sequencing (retries and times >2.5 seconds between 
	loop packets should be very rare now)
Fixed bug in archive reading that caused an unneccessary command retry
Fixed bug in splash screen that caused memory leak if application was closed before splash screen closed
Shortened the length of time the splash screen is displayed
Fixed several bugs and made improvements in connect/disconnect handling 
Changed what a virtual port sends back when the console doesn't respond to the passed through command (used to send 
	a NACK, now sends nothing)
Made virtual port receipt/response log messages for wakeup commands be verbose messages instead of info
Fixed bug that sometimes caused archive retrieval from console to fail at the top of the hour
Improved handling of archive retrieval retries (no more infinite retries)
Added short term caching for more console commands (improves performance by reducing demands on console, especially 
	when client weather programs resend a command)
Fixed bug that sometimes put packets in the cache even when the packets were NACKs or bad CRCs
Added additional error checking code to more gracefully handle bad data (especially illegal conversions of text to numbers)
Fixed bug that sometimes caused file opens to fail

v. 0.2.0 Beta (Feb 18 2006)
Made VirtualVP a system tray application, displaying a tray icon (green background when connected, yellow when 
	disconnected), and minizing to the tray
Added popup menu for tray icon
Added new program icons
Lots of testing and fine tuning communication timing and command sequencing to console to minimize the chances of a 
	missed loop packet as much as possible
Made further refinements to the log and main screen messages
Fixed some bug in connecting and disconnecting
Fixed a bug that occurred when the program was run without there already being an archive cache file
Fixed a bug that wrote to the archive cache at startup even when the archive to disk option was not set
