+       * 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.
