Support for Qt for MCUs

Standard and Premium support

Qt offers product support at different levels to help you solve technical challenges. For an overview on different support levels and best practices, see Qt Support.

Support duration

A Qt for MCUs version is available under Standard or Premium support for a limited duration only. Starting from Qt for MCUs v2.0.0, regular and Long Term Support (LTS) versions (x.y.0) are supported for six (6) and eighteen (18) months respectively. The support duration for both regular and LTS versions begins from the release date.

Note: If you need support for an older version that is no longer supported, purchase extended support. Extended support allows you to ask questions and report issues on that specific version.
