Meet "Sealed messaging" functionality

 New versions of Bopup IM client/server software introduce all-new functionality called "Sealed messages". This is a new type of instant messaging that requires an opening (unsealing) text messages before they can be viewed and read. Once message is unsealed the sender gets a notification on that and unsealed date/time is added into conversation.

The new function is enabled on the communication server and after that it appears in the messenger options. The sealed messages can be sent among regular instant messages since there can be 2 options available in the sending dialog — send sealed or regular message. But it is also possible to configure the messenger and always exchange with sealed messages.

Turning on the sealed messaging on the IM server

When a new sealed message is received the messenger hides a whole conversation and notifies a user that it is required to unseal the message to see and read it.

Within a getting the recipient's reaction by a sender that the message has been opened and viewed the sealed messaging makes overall communication more secure and confidential. In some cases it prevents viewing and reading arrived messages by someone who may stay close to the recipient's workstation.

Major update of Bopup Communication Server — Version 5.11.0 is released

 New version 5.11.0 of Bopup Communication Server is available for download. This version comes with great improvements in SQL queries that improves overall speed of the communication and fixes many related issues. Among internal improvements the server added many interface changes and enhancements.


Connectivity and overall speed improvements

The recent release of the IM server fixes issues that could appear on a greater amount of concurrent connections. Previous versions of the server could add many warnings and SQL exceptions to Event Log viewer, and users couldn't connect to the server at the same time. Another fixes belongs to connection limit error that could appear on messenger startup. So this version is an important update.

Fixed issue with logging file transfers on disabled Message History

The new version fixes saving file transfers into history log when it is turned off. This problem occured only for file exchange. Now the server console shows a dialog when Message History option is switching off that lets keep or delete existing archive on the server.


Showing computer/DNS name for user accounts in addition to IP address

Now the server resolves and adds host name for connected users to show it everywhere in Management Console within IP address. It is a useful option if the server runs on a local network and lets administrator see user's workstation names. Host name is shown in the Presence Status, on user profile page and in archiving views that shows instant messages and file transfer information.

Better integration with Active Directory in the IM server, and useful updates in the messenger apps

 We released new versions of both Bopup Communication Server and client applications including Bopup Messenger and Bopup Observer. 

The new version 5.10.10 of the instant messaging server provides great improvements in importing users from Active Directory catalog. It comes with a major update of bcscmd.exe command line tool which added support for new switches for better integration with LDAP.

New keys for /LDAP switch now can be the following:

/LDAP [update|sync|syncall] [bygroups] [createunits] [creategroups] <names> 

[createunits] switch works like a checkbox in the Active Directory Import Wizard and allows to create Organizational Units on the communication server that are similar to OU tree in Active Directory or LDAP Groups (depending on import criteria);

[creategroups] switch is similar to the key above but creates messaging groups on the server instead;

<names> is an optional parameters that includes name of OUs or LDAP Groups to limit a search for user accounts in the specified objects. Several names must be separated by commas;

The Active Directory Import Wizard now can display hidden settings on it's Welcome page.

These settings can be also set from Windows registry and allows to import computer names instead of user accounts and parse for uses' middle names the DispayName value of a user object. This is mostly important in countries from Eastern Europe.

Client messengers now support hotkey button to call the application. Previously it could not be set up by administrator but now can be configured on the IM server from a range of A...Z letters.

Here is also improvement of automatic re-connect to messaging server on exiting from Sleep/Suspend mode in the messengers.

Meet all-new "All-In-One Chat" interface mode in Bopup Messenger client

We are proud to announce new version 7.4.0 of Bopup Messenger client which now supports a single window mode.

Over the past years the messenger's user interface had not undergone global changes and included the main window with the user's contact list and separate chat dialogs with the ability to open several at once.

Classic interface with ability to have several conversation windows in the messenger

At the same time, thanks, among other things, to public messengers, instant messaging software started to use the interface with a single chat window. This became a de facto and affected, in turn, corporate IM software.

Therefore the new version of Bopup Messenger now supports a switch the interface mode within a single "All-In-One Chat" window.

The new mode is activate through program settings on the "Interface mode" tab. The regular look-and-feel mode with few conversation windows is now called "Classic Messenger".


Within the new release of the IM client we updated Bopup Communication Server which includes new  version of IM Client Configuration Tool. It lets enable the appearance mode in the messengers remotely and centrally on the server.
