This marks the acceptance of CRAN Release 2.6.1 (submitted 0c2085c, which is too old to be tagged in this release).

Updates by patch version since last CRAN release.

soilDB 2.6.1 (2021-04-07)

Connections to local NASIS and various MS Access databases now use DBI and odbc, replacing RODBC
New methods dbConnectNASIS and dbQueryNASIS for NASIS access with read-only credentials, fetching query results, and closing the DBIConnection upon completion
NASIS methods use dsn argument to specify a local "static" SQLite file containing NASIS tables, or custom DBIConnection to a database with NASIS schema
- Default dsn = NULL uses "nasis_local" ODBC connection to local NASIS SQL Server
Horizon depth logic checking is now done with aqp::checkHzDepthLogic(), powered by {data.table}
Added several new SDA query methods based on https://github.com/ncss-tech/ssurgoOnDemand by @jneme910 and @cferguso:
- get_SDA_property, get_SDA_interpretation, get_SDA_muaggatt, get_SDA_hydric, get_SDA_pmgroupname

soilDB 2.6.0 (2021-02-18)

OSDquery gets a new argument (everything) for searching the entire document
fetchNASIS(..., rmHzErrors=TRUE) -- spurious removals of data due to missing "extended" records. fetchNASIS now uses aqp::horizons<- after building a minimal SoilProfileCollection from NASIS site and horizon tables. This allows aqp integrity methods to trigger where needed--preventing unintentional re-ordering or removals of "valid" horizon data.
