There's also a packaging point of view to take into account (thinking to<br class="">
OSGeo4W in particular). For a 2 year LTR, you likely need to make sure that<br class="">
the dependencies of the LTR are controlled independently of the ones of QGIS<br class="">
master. You might want to decide to update one of the dependencies in the LTR<br class="">
(like upgrading to a new patch release of a dependency), but this must be a<br class="">
choice, not a mechanical consequence of an upgrade of QGIS master.<br class="">
<br class="">
Another thought is that some dependencies of QGIS (thinking to GDAL & PROJ)<br class="">
don't have a 2 year life span for a given release, but more a 1 year one<br class="">
