</div> Essentially 3 years of bugfixes, improvements and speedups. There has<br>
been *thousands* of commits since.<br>

</div> At the application API level there hasn't been that many changes (i.e.<br>
it won't take you that long to port your application). The<br>
design/philosophy/usage stays the same. There might have been some<br>
slight API changes, but they are well documented (see links below).<br>
<br>
Where the most happened is the underlying (core/element level)<br>
improvements. Essentially you will end up with more optimized/reliable<br>
configuration and data passing.<br>
* Better memory usage (less copies, usage of target memory/layout<br>
whenever possible, ...)<br>
* Better negotiation, and reliable/faster re-negotiation<br>
* From the above, you will end up more often with the most optimal<br>
data/processing path between the various elements in your pipeline<br>
* Usage of HW-accelerated components/systems (without having to<br>
custom-craft your pipelines) when possible<br>
* And obviously the past 3 years of improvements/speedups<br>

</div> You'll indeed get more support from the gst community if you use<br>
latest stable series :)<br>

Depends on your application/usage, but there are also new<br>
features/elements available. At the top of my head: DASH support, GL<br>
support, ...<br>

</div> If you just have an application and don't have custom plugins, it's<br>
not that hard. The concept and design at the application level have<br>
stayed the same.<br>
If you have custom plugins it's a bit more work. Check if there isn't<br>
already a new element that does the same thing upstream. If it's a<br>
custom plugin that could benefit the community, maybe it would be<br>
worthwile proposing it upstream (in which case the community could help<br>
you port it).<br>
