QGIS is updated to v3.10.7 LTR & 3.14.0 and GDAL Complete is updated to 3.1.1.
NOTE: PDF read support is not included in GDAL/QGIS yet. I’m working on it. It will be built into GDAL this time due to the licensing difference in the new base PDF library, but is difficult to get built properly.
NOTE: In attempting to update GDAL on an old Mac I discovered that it does not work on Sierra. I’m sure I have all the options set to enable it on Sierra, but it’s possible the updated Xcode on my development Mac has a bug with this. If this is the case then I will not be able to fix it and I will have to bump the system requirements to High Sierra. By dependency, this affects QGIS, PostGIS and pgRouting. It’s likely Postgres is also affected directly.
UPDATE: The QGIS 3.14 installer was not configured correctly and overwrote QGIS LTR. Now fixed.
UPDATE 2: I think I figured out the Sierra crash problem – it was really an old hardware problem, now should be fixed. System requirements now back down to Sierra.
