v1.3.0 as it appears on CRAN

• Fix Rcpp compilation under Windows (#79)
• SET/RESET SESSION queries are now correctly respected when used under dbGetQuery.
  PrestoConnection no longer has parameters slot but dbConnect remains backward
  compatible. Manual change to parameter is still possible via conn@session$setParameter() (#77)
• Adapt to changes in dplyr version 0.7.0, mainly around the remote
  backend support being split to dbplyr. This should be backwards compatible
  back to dplyr 0.4.3 (#76)
• Add support for the REAL data type (#70)
• Allow specifying the connection source (#68)
• Drop RCurl dependency (#67)
• Return DECIMAL data types as characters as opposed to numeric's
  previously (#64, fixes #60)
• Add support for new integer data types (INTEGER, SMALLINT, TINYINT) (#59, fixes #56)
• Migrate the json to data.frame construction from pure R to Rcpp for 10x
  speed gains! (thanks @saurfang) (#57, #58)
• Fix dbListFields to use the nextUri instead of infoUri (#55)
• Don't drop data for duplicate column names (#53)
