New Features in This Release

Loupe Desktop Session Search/Filter on Details

The free-text session search and filter now checks the individual Details field of each log message as well as the caption/description/exception information.

Loupe Server Session Lists Performance & Filter Improvements

The Latest Session and application-level Session displays now remember the last filter options set during the current user session.  This means if a user drills into a session from a sessions view and navigates around, then returns to that session view it will remember the most recent filters they set.  This improves several user flows where users are moving in and out of the same session list during an investigation.  The API methods that support these views have been optimized with new database indexes to significantly reduce database load and improve response time.

Loupe Server Docker Compatibility

It's now possible to containerize Loupe Server as a Windows container.  Loupe Server now supports configuration from environment variables using Loupe__Server__[Section]__[Property].  Note this is two underscores (_) in a row as a delimiter, matching the behavior of .NET Core.  To containerize, you will need to contact Gibraltar Software for a license key file for portable licensing.

Compatibility

Loupe 4.x is generally backwards compatible with 3.0 with the following notes:

• Agent: Requires Server version 4.0 and Desktop 4.0 due to new data types introduced in this version.
• Server: Fully backwards compatible with Agents 3.0 and later. Older Loupe Desktop clients will not be able to use AddIns.
• Desktop: Compatible with Server versions 3.7.0 and later.  Compatible with any version of Agent.
• Extensions must be modified:  Any Loupe Addin developed for an Loupe 3.* will need to be updated to use the new Loupe Extension types and repackaged.  Confirmation information has been moved so each extension will need to be reconfigured once it is installed.  See Loupe Extensions - Getting Started for more information.
