 Dear Reviewers:
 
-I built this package using [R CMD build .] and checked it with command [R CMD check --as-cran rglobi_0.2.20.tar.gz] on my Ubuntu 18.04 LTS Bionic Beaver (4.15.0-55-generic) machine running R 3.6.1 . Also, the checks were executed on travis-ci.org (running Ubuntu) and winbuilder (running windows).

 IMPROVEMENT
-* Use readr package to handle incoming csv streams to help avoid encoding issues on Windows . Also see https://github.com/ropensci/rglobi/issues/33 .
-* remove debug messages
-* updates reference to https://github.com/globalbioticinteractions/globalbioticinteractions after repo migration from https://github.com/jhpoelen/eol-globi-data .

-The remaining note for this version is:
-
-Possibly mis-spelled words in DESCRIPTION:
-  Biotic (3:30, 5:24)
-  Cypher (9:46)
-  GloBI (5:45, 5:53, 10:60)
-  rglobi (7:33)
+* use query cache for unit tests to make tests less dependent of state of online api
 
 I've checked the mis-spelled words and confirmed that they are in fact not mis-spelled.
