We’re back with a small re-release of our recent 5.1 Helion release. Following our usual practice for stable releases, we’ve bundled together several important fixes that have come to light since the original 5.1 launch, along with a new Sidekick sidebar feature.

This release focuses on stability improvements across WARP, the debugger, and enterprise collaboration, plus some nice UI enhancements. For users on our development branch, these fixes are already available alongside additional features.

UI

• Feature: New Sidekick sidebar widget (can be hidden by installing Sidekick or right-clicking and choosing “hide”)
• Improvement: “Show Condition As Inverted” was selectable in situations where it should have been unavailable
• Fix: Several fixes related to the URL handling logic impacting file opening on startup

Analysis

• Improvement: Support for rebased IDB import
• Improvement: Handle ELF files with no program headers
• Fix: Memory leak when applying debuginfod metadata

WARP

• Fix: WARP sometiems clobbered user-type information
• Fix: Duplicate setting registration
• Fix: WARP function symbols persisted across matched functions
• Improvement: Symbol and comment application changes

Enterprise

• Fix: Important fix for enterprise collaboration failing to sync, “failed to read any data for field” error.
