pool 1.0.4

• Switched from hosted MySQL database to local SQLite database in examples.

pool 1.0.3

• Now explicitly requires DBI 1.2.0 (#178) and messages if you're using an
  old dbplyr (#179).

pool 1.0.2

• No longer depends on the withr package, by instead requiring R 3.6.

• Add wrappers for dbplyr generics db_col_types() (#171) and
  db_copy_to() (#172).

• Pool no longer generates spurious messages about needing to use
  in_schema() or avoiding the use of ident_q().

• Add support for new DBI generics that return Arrow objects.

pool 1.0.1

• copy_to() now returns a tbl that uses the Pool.

• Added missing methods for sql_join_suffix() (#165) and
  sql_query_explain() (#167).

pool 1.0.0

New features

• Pool has been re-licensed to MIT (#158).

• dbPool() gains an onCreate parameter that allows you do something to
  every connection that pool creates. This is useful for setting options that
  you want to apply to every connection (#98).

• New localCheckout() checkouts and then automatically returns an object.
  It only works in function scope.

Minor improvements and bug fixes

• Pools now get a useful print method (#140).

• pool now implements the dbplyr 2.0.0 interface, eliminating warnings when
  using pool with dplyr (#132).

• Pool errors and warnings have been reviewed with an eye to making them
  more immediately actionable (#145).

• Objects are now validated once on first checkout to ensure that the
  object and validation strategy are both ok.

• Added support for SAP HANA databases (@marcosci, #103).

• dbPool() and poolCreate() now default to validating every 60s, rather
  than every 600s. This makes pools a little more robust to shorter connection
  timeouts (#149).

• dbPool()'s validateQuery is now actually used (#153).

• DBI methods should dispatch correctly in more cases; in particular
  dbReadTable() and friends will now work correctly when used with
  DBI::Id() (#120).

pool 0.1.6

• left_join() and friends once again work with pool objects (#111).

• dbPool() objects previously could leak memory. (#115)
