Hugo fast render vs full rebuild for local development

Hugo fast render or full rebuild for shared template edits

I need `hugo server` to refresh every derived output—section listings, taxonomies, menus, sitemap.xml, and RSS—immediately after I edit a shared template or data file, without restarting the development server.

Fast rendering updates only pages directly touched by the changed file, so indirect dependents can remain stale. `--disableFastRender` forces a complete rebuild on every change, which keeps derived pages consistent but slows reloads on larger sites. Default render behavior and flag support depend on the installed Hugo release.

Cross-page consistency or faster incremental reloads: which trade-off suits a medium-sized site, and what version check confirms the server’s default render mode?
