1.2.0-alpha2: forward-port of 1.1.0-alpha2 fixes onto ESI baseline First public alpha of the 1.2.x track. Same ESI render element and fragment-route work as the unreleased 1.2.0-alpha1, plus the two response-subscriber correctness fixes from 1.1.0-alpha2 brought forward via merge of 1.1.x: - Admin routes no longer emit any LSCache header (AdminContext- based skip, covers /admin/* plus contrib routes flagged _admin_route: TRUE). - Debug log messages contain resolved values rather than literal @placeholder text (inline sprintf substitution, works in dblog UI and drush watchdog:show alike). The 1.2.0-alpha1 tag was cut but never published as a release node, since the alpha1 field-test loop ran on 1.1.x first and surfaced bugs that needed to land before any 1.2 alpha hit operators.
