From 1e13dac952d8f6cce7964aef27e98fa2e9da1eb7 Mon Sep 17 00:00:00 2001
From: Christian Cleberg <hello@cleberg.net>
Date: Fri, 3 Apr 2026 16:59:04 -0500
Subject: Release 1.4.0

Add richer SSL/TLS inspection details including negotiated TLS version,
cipher suite, full certificate chain display, crt.sh lookup, and HSTS
preload status. Persist HSTS preload in history/export and run the
preload check in parallel with the SSL lookup.
