From d1e69aee849e35475c9f563f815f27728e5a88da Mon Sep 17 00:00:00 2001 From: CJ Steiner Date: Thu, 22 Jan 2026 16:18:14 -0600 Subject: [PATCH 1/6] Honor tag creation date properly MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * "Ignore tags older than" field was using the commit creation date rather than the tag creation date. * Change correctly distinguishes between: - Annotated tags → Uses tag creation time (fixes the bug) - Lightweight tags → Uses commit time (backward compatible) This enables the "Ignore tags older than" feature to work correctly when new tags are created on old commits.
