+ * doc/: Added a README on how to build doc; now builds on Ubuntu.
+ * sql/oodml.lisp: READ-SQL-VALUE now has explicit method for
+ handling double-floats and the default method will no longer
+ attempt to convert values that have already been converted.
+ * sql/syntax.lisp: Introduce file-enable-sql-reader-syntax which
+ enables the syntax for the scope of the file without trying to
+ keep track of the current syntax state.
+ * sql/pool.lisp: Introduce
+ clsql-sys:*db-pool-max-free-connections* which is a heuristic
+ threshold for when to disconnect a connection rather than
+ returning it to the pool.
+ * sql/pool.lisp: Check connections for validity before returning
+ to the user.
