PyQtGraph 0.11.0 vs 0.11.1

[Dragos Tothazan]

Hello,

I'm currently working on a big project that uses Python 3.6.0,  PyQt 5.10.1, Numpy 1.15.4, and currently the 0.10.0 version of pyqtgraph. On this project, I am responsible for upgrading the version of pyqtgraph from 0.10.0 to either 0.11.0 or 0.11.1 which is the latest version. I didn't quite understand from your documentation / repo read me, but is it safe to say that 0.11.0 version uses the same dependencies like 0.10.0 did? And 0.11.1 needs updating the Python version to at least 3.7.0, Numpy 1.17+ and PyQt 5.12+? It is really important for us to know these differences, because if 0.11.0 uses the same dependencies as 0.10.0 it will be an easier integration and hope it will not cause any problems (I think your API is still the same in 0.11.0 as it was in 0.10.0). I am looking forward to your response. 

Thank you, 

Dragos T.

Hi Dragos.

PyQtGraph through 0.11.1 supports Qt 4.7+ and Python 2.7+, just like 0.10.0.  The next version (0.12.0) will only support Qt 5.12+ (including Qt6!) and Python 3.7+ and numpy 1.17+.  

Future releases of pyqtgraph will follow a combination of NEP-29 and Qt's own support schedule; although with their move for LTS version support only being for commercial customers, we will likely reconsider more on a case by case basis; so I'm not sure when we'll drop Qt 5.12 support, but it won't be for a while.  I hope that helps.

Regarding API differences, there may be some minor differences, we've merged _hundreds_ of PRs between 0.10.0 and 0.11.1, but I don't think the API particularly changed.

Hope this helps.
