QGIS 2.18 is End of Life
QGIS 2.18 Las Palmas "End of Life"
The QGIS version 2.18 (LT-Release) is end of life.
The last bug-fix releases of version 2.18 can still be downloaded from http://download.osgeo.org/qgis/ for the coming months and years. The last 2.18 bug fix release is from February 14, 2019. There are no further bug-fix releases for 2.18.x planned, but bug fixes in the github repository can still be submitted. Organizations who still want to make use of further 2.18.x bug fixes need to self-compile their QGIS 2.18.x releases.
We strongly encourage QGIS users to upgrade to the newest LT version 3.4.
