v0.7.1

Highlights

• Updated tracing-subscriber to version 0.3.20 to address CVE-2025-58160.

• The BPF iterator program that tracks which process loaded each BPF program now fails gracefully instead of preventing bpftop from starting. This improves compatibility with kernels not compiled with CONFIG_KALLSYMS_ALL, where the required bpf_prog_fops symbol may be unavailable. While process tracking is a nice-to-have feature, bpftop now continues to function without it, displaying all BPF statistics except process information. Details: #162

• Dependencies will now only be updated to unblock features, fix bugs, or address security vulnerabilities. Several dependencies were rolled back, making bpftop easier to package for distributions like Fedora.

• Added CLAUDE.md to support LLM-assisted development. AI contributions are welcome!

v0.6.0

What's Changed

This release updates all dependencies to their latest release versions, including libbpf-rs and ratatui. We've also added a couple of UX improvements.

New Features

Scrollbar for tabular view

Thanks to @m12t, the tabular view now displays a scrollbar when the list of BPF programs exceeds the terminal window height. This enhancement makes it clear that additional programs exist beyond those currently visible.

New CLI Options

bpftop now supports the --help and --version flags. Previously, it wasn't possible to check the version information.

v0.5.0

New Feature

This version of bpftop introduces a feature to display processes that reference BPF programs. The process name and PID will be displayed in the info box when a BPF program is selected.

To achieve this, bpftop loads its own BPF iterator program, which will also be displayed in the program list.

• Add systemd journal logger via tracing crate by @jfernandez in #36
• List processes (PID and comm) holding references to a BPF program by @jfernandez in #37

Dependency Updates

• Bump libbpf-sys from 1.4.0+v1.4.0 to 1.4.1+v1.4.0 by @dependabot in #39
