+2012-04-26 Kevin Rosenberg <kevin@rosenberg.net>
+ * Version 6.2 released: thanks to all the contributors!
+
+2012-04-25 Nathan Bird <nathan@acceleration.net>
+
+ * doc/threading-warnings.txt: Adding some notes from J.T.Klein
+ about the current state of thread-safety in clsql. This should be
+ incorporated into the main docs at some point.
+
+2012-04-25 Russ Tyndall <russ@acceleration.net>
+ * sql/expressions.lisp (output-sql): on rendering update/insert
+ expression values, ensure that *in-subselect* is bound to T
+ so that the values will be correctly paren delimited
+
+2012-04-24 Nathan Bird <nathan@acceleration.net>
+
+ * sql/expressions.lisp (output-sql): on mysql CREATE TABLE
+ statements use 'ENGINE=innodb' instead of 'Type=InnoDB'. This has
+ apparently been preferred since mysql 4.1 and mysql 5.5 removed
+ type as a valid keyword.
+
+2012-03-28 Russ Tyndall <russ@acceleration.net>
+
+ * sql/sequences.lisp: [A Patch FROM 2011-07-28 changed sequences.
+ They were previously prefixed with _CLSQL_SEQ_ but are now
+ suffixed with _CLSQL_SEQ. This is likely to break existing
+ implementations using the default sequence names
+
+ setting *old-sequence-names* to T, should force using the older
+ naming scheme
+
+2012-03-27 Ryan Davis <ryan@acceleration.net>
+
+ * sql/expressions.lisp: Fixed bug with subqueries in the where
+ clause of update-records and delete-records generating invalid
+ SQL. Previously subselects in where clauses would not have enough
+ parentheses, for example: "WHERE Id IN SELECT foo_id FROM bar"
+ vs. "WHERE Id IN (SELECT foo_id FROM bar)"
+ * tests/test-syntax.lisp: Added tests for using subqueries in the
+ where clause in update-records and delete-records. Moved asserts
+ in the test-output-sql/sql-ident-table function into the standard
+ test framework.
+ * doc/appendix.xml: added :connection-string to the information on
+ ODBC connection specs, and added example code connecting to ODBC
+ databases.
+
+2012-01-05 Nathan Bird <nathan@acceleration.net>
+
+ * db-odbc/odbc-dbi.lisp: handle sql decimal type in the same way
+ as numeric type-- read into a double float.
+
+2011-01-04 Russ Tyndall <russ@acceleration.net>
+ * sql/operations.lisp
+
+ Fixed bug reported by JTK related to the not-null sql-expression
+ especially as used in conjunction with the is operator.
+
+ Made null called with more than one argument throw an exception
+ instead of silently discarding all arguments past the first
+
+2012-01-04 Nathan Bird <nathan@acceleration.net>
+
+ * db-odbc/odbc-api.lisp (%sql-driver-connect): in the call to
+ odbc's SQLDriverConnect default the WindowHandle argument to a null ptr so
+ that connecting with :connection-string will work in the default
+ case of SQL_DRIVER_NOPROMPT.
+
+ I.e. you can now do things like:
+ (clsql:connect '("DsnName" "UserName" "" :connection-string
+ "DRIVER={FreeTDS};SERVER=...;DATABASE=...;UID=...;PWD=...;PORT=1433;TDS_Version=8.0;APP=clsql")
+ :database-type :odbc)
+
+ I believe the DsnName and Username at that point are only used when
+ printing the connection information.

+ * Version 6.1.1
+ * db-oracle/oracle.lisp: Typo correction (Elias Martenson)
+
+2011-12-19 Kevin Rosenberg <kevin@rosenberg.net>
+ * Version 6.1.0
+ * db-oracle/oracle.lisp: Change length function to
+ uffi:foreign-string-length to handle foreign encodings.
+ Thanks to Elias Martenson.
+
+2011-11-28 Russ Tyndall <russ@acceleration.net>
+ * db-odbc/odbc-api.lisp, tests/test-time.lisp
+
+ In ODBC backend, avoid going through the common lisp
+ universal-time type (because it lacks support for historic dates)
+
+ *time-conversion-function* renamed to *time-format*
+
+ Patch from: Francisco Vides Fernandez
+
+2011-10-18 Russ Tyndall <russ@acceleration.net>
+ * db-odbc/odbc-api.lisp
+
+ Added type specifier so MSSQL nvarchar fields can make it through
+
+2011-09-12 Russ Tyndall <russ@acceleration.net>
+ * sql/fddl.lisp sql/generic-postgres.lisp db-mysql/mysql-sql.lisp
+ sql/generic-odbc.lisp sql/odbc-api.lisp sql/odbc-dbi.lisp
+
+ Fix bugs in list-attribute(s|-types) where passing an escaped,
+ instead of unescaped column name, caused these functions to return
+ less data than they should have.
+
+2011-08-03 Kevin Rosenberg <kevin@rosenberg.net>
+ * CLSQL 6.0.0 released
+
+2011-07-28 Russ Tyndall <russ@acceleration.net>
+
+ * db-postgresql-socket3/: Added a backend that utilized postgres
+ socket api version 3. Uses the cl-postgres project (from
+ postmodern) to handle this. Allows use of parameterized /
+ prepared queries using clsql:command-object
+
+ * sql/{expressions,fddl, generic-postgresql, ooddl}.lisp:
+ Change how database identifiers are emitted to hopefully make this
+ less brittle, and more easily intuitable.
+
+ Previously every code path that wanted to emit a
+ database identifier was responsible for coercing what was provided
+ into a correctly escaped string. Sometimes two or three functions
+ in a row were trying to correctly quote and output that string. I
+ have tried to centralize this type coercion and logic into a
+ single code path.
+
+ everything should now call (escaped-database-identifier thing)
+ immediately before splicing a database identifier into string being
+ sent to the database
+
+ * sql/oodml.lisp: added method choose-database-for-instance, which
+ allows overriding which database connections are used based on
+ object type. Can be used to prevent connection conflicts in
+ multi-threaded environments
+
+ * sql/syntax.lisp: [foo bar] and [foo.bar] read into the same
+ clsql expression now (they used to be output the same, but after
+ the above database-identifier change, they were output separately
+
+ * test/: Better, more tests, better type coercion in tests and
+ throughout (%get-int)
+
+ [edit 2012-03-28 - RT]
+ * sql/sequences.lisp: Sequences were previously prefixed with
+ _CLSQL_SEQ_ but are now suffixed with _CLSQL_SEQ. This is likely
+ to break existing implementations using the default sequence names
+
+ setting *old-sequence-names* to T, should force using the older
+ naming scheme

+ * Version 5.4.0 release
+
+2011-06-27 Nathan Bird <nathan@acceleration.net>
+ * db-odbc/: memory management improvements: leak slower
+ * MSSQL: TOP + DISTINCT work together
+
+2011-06-20 Nathan Bird <nathan@acceleration.net>
+
+ * sql/time.lisp: Handle parsing already parsed objects.
+ * sql/oodml.lisp: raise exception if we generate an update with no
+ where clause; incorporate Ryszard Szopa's patch for functional
+ expressions in :order-by
+ * sql/expressions.lisp: (listify nil) => nil instead of (nil).
+ * db-odbc/: bugfixes for working with older versions of FreeTDS;
+ support for bigints that works on mssql and postgres
+ * MSSQL improvements: use top instead of limit, IDENTITY can be a
+ column constraint, clsql:date becomes 'smalldatetime'
+
+2011-06-20 Nathan Bird <nathan@acceleration.net>
+
+ * Version 5.3.4
+ * db-postgresql-socket/postgresql-socket-api.lisp: Addendum
+ to Otto Diesenbacher's patch that had a spurious write a 0
+ byte (to terminate string) that should have been just CCL.
+
+2011-06-12 Kevin Rosenberg <kevin@rosenberg.net>
+ * Version 5.3.3
+ * db-postgresql-socket/postgresql-socket-api.lisp:
+ Patch from Otto Diesenbacher for UTF8 encoded strings
+ for CCL. FIXME: The best patch would be to use the
+ user-set encoding from the database object and use
+ UFFI's encoding strings to/from octet vectors rather
+ than SB-UNICODE and CCL specific code in this file.
+
+2011-04-21 Kevin Rosenberg <kevin@rosenberg.net>
+ * sql/generics.lisp: Add defgeneric for new
+ database-last-auto-increment-id
+
+2011-04-01 Kevin Rosenberg <kevin@rosenberg.net>
+ * Version 5.3.2
+ * db-mysql/mysql-client-info.lisp: Add recognition of
+ version 6 of MySQL client library.
+ * sql/metaclass.lisp: Fix the fix in the reader conditional
+
+2011-03-30 Kevin Rosenberg <kevin@rosenberg.net>
+ * Version 5.3.1
+ * sql/metaclasses.lisp: Fix previous patch to work
+ on non-SBCL systems
+
+2011-03-29 Kevin Rosenberg <kevin@rosenberg.net>
+ * Version 5.3.0
+ * sql/metaclasses.lisp: Apply one-line patch to fix
+ for newer SBCL (thanks to Nikodemus Siivola)
+ * many_files: Applied multiple patches from Holger Schauer
+ to improve autoincrement capability.
+
+2010-10-24 Kevin Rosenberg <kevin@rosenberg.net>
+ * Version 5.2.0
+ * db-odbc/odbc-api.lisp: Change from SBCL-specific
+ to UFFI version of octets-to-strings. Reported by
+ Daniel Brunner <daniel@dbrunner.de>
+ * sql/oodml.lisp: Apply patch from Rupert Swarbrick
+ <rswarbrick@gmail.com>: Fix behaviour with auto-inc
+ primary keys.
+ * sql/expressions.lisp, tests/test-syntax.lisp: Apply
+ patch from Russ Tyndall to quote identifiers with space
+ or special character.
+
+2010-09-20 Kevin Rosenberg <kevin@rosenberg.net>
+ * Version 5.1.4
+ * sql/{pool,database}.lisp: Pass encoding argument to
+ connections made from pool and with reconnect.
+
+2010-08-16 Kevin Rosenberg <kevin@rosenberg.net>
+ * Version 5.1.3
+ * db-odbc/odbc-{api,dbi}.lisp: Commit patch from
+ Memet Bilgin to fix issue with unicode and ODBC.
