<p>Hi Raffael,</p>
<p>3.34 will be the next LTR, but not yet in October 2023, but only starting from end of February 2024. In the table <a href="https://qgis.org/en/site/getinvolved/development/roadmap.html#release-schedule">https://qgis.org/en/site/getinvolved/development/roadmap.html#release-schedule</a> you can check the third column labeled "Long-Term Repo" to see at what time frame which version is LTR.</p>
<p>About your second question: don't nail me down on this but all 3.x versions should open with the newest 3.x version - it should be even possible to open version 2 files with the latest 3.x version.</p>
<p>Greetings,</p>
<p>Andreas</p>
