+Re-run installation_history version-column widening from the 2.4.0-to-2.5.0 upgrade.
+
+Scope (release-notes guidance — keep this quiet):
+    Servers that crossed 2.4 -> 2.5 BEFORE PR #828's fix shipped in v2.7.0 ran the
+    widen script as a no-op (it executed against master, not PerformanceMonitor)
+    and then advanced their installer_version past 2.5. The upgrade filter only
+    selects folders where ToVersion > currentVersion, so the now-fixed script is
+    never re-applied on those servers and their sql_server_version /
+    sql_server_edition columns stay at nvarchar(255) -- which truncates SQL 2022+
+    @@VERSION strings (~260 chars) on every install attempt.
+
+    This is a silent remediation for that long tail. The body is identical to
+    upgrades/2.4.0-to-2.5.0/01_widen_version_columns.sql and is idempotent: the
+    IF EXISTS guard checks max_length = 510 (nvarchar(255) in bytes) so servers
+    that are already widened, or that ran the fixed 2.4->2.5 upgrade cleanly,
+    skip both ALTERs.
+
+    For changelog purposes this is a one-line "fix": "Re-run installation_history
+    column widening for servers that hit the no-op pre-v2.7.0 upgrade (#828)."
+    Do not promote it as a new feature.
