 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.6.3
 Keywords:                |       Port:  aff4 spdlog
--------------------------+-------------------------
 It was observed in 2018 that updating `spdlog` to ≥ 1.0 would break `aff4`
 (see [85b10ef0f8/macports-ports] and
 [https://github.com/Velocidex/c-aff4/issues/38]). This knowledge never
 made it to a comment in the `spdlog` portfile or a ticket where it would
 be easily noticed when someone tried updating it. `spdlog` has since been
 updated from 0.16.3 to 1.4.2 ([bb7d7b7b6d/macports-ports]) and then 1.5.0
 ([7caf3d34e5/macports-ports]), and as expected `aff4`
 [https://paste.macports.org/ab94cd9404b8 currently fails to build]:
