About Robusta
Robusta spends a full release on security hardening and swaps out its PDF rendering stack.
Robusta ships from an alpha channel — every recent tag carries the -alpha suffix, so alpha is the release line rather than a pre-release step. The latest cut is dominated by security work: preventing signing-key leakage in email, hardening pull configs and Supabase login, a cryptography bump for CVE-2026-69247, and backported libssh2/attr/acl fixes. Alongside it, PDF generation moves off CairoSVG to resvg-py and reportlab.
