Release Notes for Version 7.51

This release is dedicated mostly to polishing various application features. It improves a lot of existing components by fixing bugs and memory leaks. It also significantly reduces application memory requirements and works around memory exhaustion issues, particularly on 32-bit systems.

New Features

This release introduces high-precision session time measurement mode. When enabled (per-session), Device Monitoring Studio uses high-precision system timer for packet time-stamping. This mode is enabled by default if Device Monitoring Studio is installed on Windows 7 or later.

Raw Data View and Structure View data visualizers now support additional packet coloring mode. Now they allow the user to choose one of three modes: no coloring, packet interlacing (coloring odd and even packets) and read/write coloring (coloring read and write packets).

Fixed Bugs

This release fixes over 200 different bugs, including crashes. A special attention has been paid to the following:

Here is a short list of most remarkable fixed bugs:

Correct emergency session termination
When resources are low, Device Monitoring Studio is now more robust in stopping affected high-data rate monitoring sessions, or session processing modules. This mostly affects 32-bit systems or systems with slow secondary storage.
Log file repairing
Device Monitoring Studio has always repaired damaged log files on startup. If log file was large, it introduced a startup delay (only splash screen was visible and application appeared to be hanging). Now a progress bar is shown to tell the user that application is alive.
Operating with limited processing resources
During monitoring Device Monitoring Studio uses available disk space as configured in the Data Processing Tab (invoked by Tools » Settings menu command). We have fixed a number of bugs related to Device Monitoring Studio operation under limited settings (like 1% on a single disk and 0% on all others).
"Exporter" data processing modules: Raw Exporter, Text Exporter and Data Recording
A number of bugs have been fixed in exporter modules. CPU and memory usage have been carefully profiled and optimized.

Memory Usage Optimizations

This release also brings improvements to Device Monitoring Studio memory usage strategies. All critical paths have been carefully analyzed and profiled, resulting in memory usage savings of up to 10 times in several places. Application is now much more robust on systems with lower amount of RAM. In addition, when installed on 32-bit operating systems, application is now capable of sustaining much higher data rates during monitoring.

Reduced memory demands now also allow to start "heavier" monitoring sessions - sessions with more data processing modules, complex custom protocols and filter expressions.

Supported OSes

This release drops support for 64-bit Windows XP and Windows Server 2003. 32-bit versions of these operating systems are still supported.

Remote Source now requires at least Windows Vista and will not be installed on Windows XP or Windows Server 2003.

Future releases will drop support for Windows XP and Windows Server 2003 entirely.

UI Layout Update

This release will install new default UI layout (tool windows and toolbars). Any user-defined layout will be overwritten.

Release Notes for Version 7.26

Fixed Bugs

Crash after removing data processing modules from running session
Application crashed when a data processing module was removed from a running session.
Invalid behavior after changing visualizer's root protocol
When Root Protocol was changed for the active visualizer, it could result in removing all monitored packets due to incorrect interpretation of empty display filter.
Crash after closing Structure View or Raw Data View visualizers
Application could crash after closing Structure View or Raw Data View visualizers.
Crash in Text Exporter
Text Exporter crashed during network monitoring.

Updated Features

Trial period extension
Trial period has been extended to 21 days from 14 days.

Release Notes for Version 7.25

Fixed Bugs

Fixed "Minimize to tray" command line switch
Command line switch -m did not work as expected.
Fixed script editor auto-indentation feature
Script editor could incorrectly apply auto-indentation in some cases.

Updated Features

Documentation for predefined fields and functions

Automatic reconnect for remote sessions
If network connection error occurs during remote monitoring, Device Monitoring Studio automatically tries to reconnect to remote server and continue monitoring.
Typescript updated to 1.5
Built-in Typescript compiler has been updated to version 1.5.

Release Notes for Version 7.22

Fixed Bugs

Application crash if running multiple copies
Application crashed when multiple copies were launched by different users.
Crash during scrolling or exporting a view in long monitoring session
An application crash was possible when the user tried to export or scroll data window in a long monitoring session.
Duplicate entries in Capture Filter Intellisense

Incorrect installation state if used by different user
Some default configuration settings were missing if application was installed under one user account and then used under another account.
Improved stability on startup
Improved compatibility with third-party software that modifies application files during startup. This has caused early re-compilation of protocol definition files and could lead to crash.

Updated Features

Sorted tool windows in View » Tool Windows menu
Tool windows in View » Tool Windows menu group are now sorted, which makes navigation easier.

Release Notes for Version 7.21

Several reported bugs have been fixed, including application crashes.

Compatibility Notes

IMPORTANT! Network Monitor 7.06 (and all previous versions) does not correctly work on Windows 8.1 Preview! This version's installer detects Windows 8.1 Preview and prohibits you from installing Network Monitor component on this OS.

Release Notes for Version 7.05

Multi-source Monitoring
Device Monitoring Studio supports joining monitored data from multiple sources of the same type into a single monitoring session. It is possible to monitor two or more serial ports, USB devices or network adapters. Device Monitoring Studio makes sure packets are correctly sorted and presented through a number of supported data visualizers. Data logging also supports multi-source sessions.
Windows 8 Support
DMS 7 officially supports Windows 8 and Windows Server 2012.
Built-In and Custom Protocol Parsing
DMS 7 extends protocol parsing support for all monitoring modules: network, USB and serial. In addition, this version has new implementation of protocol parsing, which is more flexible and greatly improves performance.
New Data Processing Category
New processing category is introduced: data exporters. These are components that process monitored data in some way, but do not produce any visible output on the screen. Data recording module now belongs to this category. Other data exporters are Raw Data Exporter and Text Exporter. Both these exporters are capable of using built-in or custom protocol definitions to parse monitoring data before exporting.
Parallel Processing
New version of Device Monitoring Studio utilizes multiple cores for more responsive monitoring session operation. It basically allows the user to still perform real-time monitoring of 1 Gb network transfer without packet loss and slowdowns while having such "heavy" processing like Capture Filter and Display Filter configured for a monitoring session.
Device Tool Window
New tool window that displays all devices the user can monitor in a single customizable view. For each supported device, its image, type and current state are displayed. The user may start, stop and configure monitoring sessions, view device properties, restart and rename devices.
Sessions Tool Window
New tool window lists all currently running sessions and their properties. It allows you to close data visualizers, add new data processing modules, pause, resume or stop sessions. It also allows you to quickly change data processing modules configuration. For example, for data recording, the current log file size is displayed. By clicking "End Stream", the user ends the current stream and starts a new one.
Protocol-Based Data Visualizers
Structure View and Raw Data View data visualizers for USB, Serial and Network with additional filtering (Display Filter) and ability to specify root protocol.
Automatic Layout Loading
DMS 7 automatically loads separate tool window and command layout when monitoring session is started. Thus, until a session is started, a layout which simplifies device discovery and information retrieval is used. After the session is started, another layout is automatically loaded streamlining monitoring session usage. Both layouts may be customized by the user.
Global Configuration Switch
Device Monitoring Studio provides you with a global switch to quickly turn it into Serial Monitor, USB Monitor or Network Monitor. This switch may be used in combi installations to temporary hide unneeded components.
Session Configuration Window

New Session Configuration window greatly simplifies session creation and modification. There is a list of configured sources at the top of the window. Below are optional device configuration settings, buttons to add more devices and remove existing ones.

Depending on the type and number of configured sources, a list of available processing modules is populated. It is divided into two main categories: visualizers and exporters.

Double-click on the processing module to add it to the current session. Some of modules support configuration. Customized processing modules may be saved for future use.

Finally, the user specifies a capture filter, a generic (protocol-based) conditional expression used to filter out specific monitored packets.

Release Notes for Version 6.43

BSOD on Windows 8
Network Monitor may cause the computer to crash after returning from sleep on Windows 8. Fixed.
Large network adapter count bug
Network Monitor may fail to list the available network adapters if there are many of them on a computer.

Release Notes for Version 6.35

Process packet data with Hex Editor Neo
New "Process with Hex Editor Neo" command has been added to Raw Data View visualizer. It copies the selected packet data and opens it in installed copy of Hex Editor Neo.

Release Notes for Version 6.31

Packet Builder
New component Packet Builder allows you to create packets either from scratch, from predefined or custom templates or from one of the monitored packets. Created packets may later be ordered and sent to the network via one of the installed network adapters.

Release Notes for Version 6.25

Next Connected Device
Network Monitor can now automatically attach to next connected network interface.
Process name resolving
Network Monitor now displays the sending or receiving process name, in addition to its ID.

Multiple packet selection in Packet View
It is now possible to select multiple packets in a data visualizer for copying and exporting.
Updated address format
Network Monitor now uses another display format for network addresses, such as IP or MAC, better adhering to standard address representation.
Protocol definition files fixes and updates
This release introduces updates and fixes to protocol definition files, notably the DNS protocol.
Improved setup speed
Speed of Device Monitoring Studio setup application has been greatly improved. Installer now needs to update less files and system settings and operates much quicker.
Improved application start-up time
We have improved the applicaiton start-up time by reducing time required by various components to initialize and allowing several components to initialize in parallel.
Improved performance
This release has improved performance thanks to optimization of various core components and the use of new compiler.
