# SQLObject 2.1.2

Released 15 Mar 2015.

- Using fdb adapter for Firebird was ported from SQLObject 1.6.6.

# SQLObject 2.1.1

Released 10 Mar 2015.

- Minor fix in PostgresConnection was ported from SQLObject 1.6.5.

# SQLObject 2.1.0

Released 6 Jan 2015.

## Minor features

- In queries generated with SQLObject's tables columns are sorted in the order they are declared in the table.
- In queries generated with sqlbuilder's Insert/Update, if values are passed using dictionaries, columns are sorted alphabetically.
- Tables in SELECT...FROM clause are sorted alphabetically.
- MySQLConnection, PostgresConnection and SQLiteConnection have got a new method listDatabases() that lists databases in the connection and returns a list of names.
- MySQLConnection, PostgresConnection and SQLiteConnection have got a new method listTables() that returns a list of table names in the database.

# SQLObject 2.0.0

Released 20 Dec 2014.

## Features & Interface

- DateTimeCol and TimeCol can read and write values with microseconds.

  WARNING: microseconds are supported by MariaDB since version 5.3.0 and by MySQL since version 5.6.4, and even these versions require special handling: columns to store microseconds have to be declared with precision 6: TIME(6), DATETIME(6), TIMESTAMP(6). SQLObject does the right thing when creating a new database but existing databases have to be changed: run something like `ALTER TABLE name MODIFY COLUMN col TIME(6)` for every column that you want to store microseconds.

  WARNING: backward compatibility problem! Date/Time columns created with microseconds cannot be read back from SQLite databases (and perhaps other backends) with versions of SQLObject older than 1.7.

## Minor features

- PostgresConnection, when used with fromDatabase=True, sets alternateID for unique columns.

## Development

- Development was switched from Subversion to git.

## Documentation

- Old news were restored back to version 0.2.1.
- News.txt was split into 5 small files.

- A bug was fixed in SQLiteConnection - clear _threadPool on close().

# SQLObject 1.1.4

- Documented sqlmeta.dbEncoding and connection.dbEncoding.

# SQLObject 1.1

Released 20 Jun 2011.

## Features & Interface

- SelectResults (returned from .select()) is allowed in IN(column, list).
- A different workaround is used in SQLiteConnection to prevent PySQLite from converting strings to unicode - in the case of a registered text conversion function PySQLite silently converts empty strings to Nones; now SQLObject uses text_factory instead and properly returns empty strings.
- It is now possible to declare one encoding for all UnicodeCol's per table (as sqlmeta.dbEncoding) or per connection (as connection.dbEncoding). Default (if dbEncoding is found neither in column nor in table nor in connection) is 'utf-8'.

## Source code and internals

- All 'mydict.has_key(name)' checks were replaced with 'name in mydict'.

# SQLObject 1.0.3

Released 30 Aug 2011.

# SQLObject 1.0.2

Released 8 Aug 2011.

# SQLObject 1.0.1

Released 30 May 2011.

- A syntax incompatibility was fixed in SQLiteConnection that prevented SQLObject to be used with Python 2.4.

# SQLObject 1.0.0

Released 28 Mar 2011.

## Features & Interface

- Major API change: DB URI parser was changed to use urllib.split*() and unquote(). This means any username/password/path are allowed in DB URIs if they are properly %-encoded, and DB URIs are automatically unquoted.
- A new module `__version__.py` was added. New variables `version` (string) and `version_info` (5-tuple: major, minor, micro, release level, serial) are imported into `sqlobject` namespace.
- In SQLite, id columns are made AUTOINCREMENT.
- Parameter `backend` in DB URI is no longer supported, use parameter `driver`.
