Version 1.4

New Features

• fdb.schema submodule extended with support for user privileges.

Improvements

• fdb.services.User.load_information() method to load information about user from server.
• fdb.ibase content cleanup and additions.
• fdb.blr submodule with BLR definitions.

Bugs Fixed

• PYFB-37 - Unicode Strings incorrect not allowed for insertion into BLOB SubType 1.

Version 1.3

New Features

• fdb.monitor submodule for access to / work with monitoring tables.
• New fdb.Connection.monitor property for access to monitoring tables.

Improvements

• closed property and clear() method for Schema.
• Unit tests reworked.

Bugs Fixed

• Unregistered: Bug in fdb.schema.Schema.close() and fdb.schema.Schema.bind().

Version 1.2

New Features

• fdb.schema submodule for access to / work with database metadata.
• fdb.utils submodule with various helper classes and functions.
• New fdb.Connection.schema property for access to database schema.
• New ConnectionWithSchema connection class that provides more direct access to database schema than Connection.
• New fdb.Connection.firebird_version, fdb.Connection.version and fdb.Connection.engine_version properties.
• New Connection.ods read only property that returns ODS version number of connected database. There are also new module-level constants ODS_FB_20, ODS_FB_21 and ODS_FB_25.
• New fdb.Connection.query_transaction property. This is ReadOnly ReadCommitted transaction that could be active indefinitely without blocking garbage collection. It’s used internally to query metadata, but it’s generally useful.

Improvements

• Optional PEP 249 (Python DB API 2.0) Extensions

  • Connection.Error, Connection.ProgrammingError, etc.

    All exception classes defined by the DB API standard are exposed on the Connection objects as attributes (in addition to being available at module scope).

  • Cursor.connection

    This read-only attribute return a reference to the Connection object on which the cursor was created.

• Cursor.transaction read-only attribute returns a reference to the Transaction object on which the cursor was created.

• Optimized wekref management, especially for PreparedStatement.

• create_database now supports two methods for database screation. You can specify CREATE DATABASE statement (as before) or provide set of named database parameters (SQL statement is created automatically from them).

• Functions connection and create_database now take optional keyword parameter connection_class to obtain instances of different class instead Connection.

• Support for legacy (pre-2.5) shutdown mode with mode fdb.services.SHUT_LEGACY.

• fdb.Cursor.executemany() returns self, so it could be used directly as iterator.

• Documentation inprovements.

Bugs Fixed

• Unregistered: buffers parameter of fdb.connection doesn’t support values greater than 255.
• Unregistered: Lowercase character set name passed to fdb.connect may result in wrong funcion of automatic data conversions and other failures (exceptions raised).

Version 1.1.1

Bugs Fixed

• PYFB-35 - Call to fetch after a sql statement without a result should raise exception
• PYFB-34 - Server resources not released on PreparedStatement destruction

Version 1.1

New Features

• Context Manager for transactions.

Bugs Fixed

• PYFB-30 - BLOBs are truncated at first zero byte

Version 1.0

Improvements

• Removed dependency on fbclient library to be present at import time (PYFB-24)

Bugs Fixed

• PYFB-25 - Truncate long text from VARCHAR(5000)

Version 0.9.9

New Features

• Firebird ARRAY support.

Other changes

• Cursor.execute() returns Self, so it could be used as iterator.
• Reading output from Services now uses more efficient method to get data from server.

Bugs Fixed

• Fix: precision_cache in Connection works as intended.

Version 0.9.1

Just bugfixes to make FDB work on P3K again.

Version 0.9

New Features

• Documentation; both in-source (in Sphinx autodoc format) and Sphinx (html)
• Services API completely reworked

Other changes

• Unregistered bugs fixed.
• Various optimizations and cleanup
• Object reference graph optimalizations
• Many new tests in test suite

Version 0.8.5

New Features

• Support for Firebird stream BLOBs (see ReleaseNotes for details)
• Documentation (stub, from KInterbasDB 3.3.0)

Bugs Fixed

• Fix for PYFB-17 and PYFB-18 (see our JIRA tracker for details)
• Fixes for automatic unicode conversions + refactoring
• Some optimizations

Version 0.8

New Features

• Support for Firebird Event Notifications - JIRA entry <http://tracker.firebirdsql.org/browse/PYFB-8>

Bugs Fixes

• database_info (isc_info_firebird_version) fails opn amd64 linux - JIRA entry <http://tracker.firebirdsql.org/browse/PYFB-16>
• more than 2 consecutive cursor open execute and iter fail - JIRA entry <http://tracker.firebirdsql.org/browse/PYFB-15>

Version 0.7.2

New Features

• Python 3 Support (thanks to Philippe Makowski)
• Support for Distributed Transactions

And as always, some (unregistered) bugs fixed.

Version 0.7.1

Bug fixes.

Version 0.7

Initial release.

Almost feature-complete (ready for 95% of users), but it could be still buggy (it’s beta!), and the code wasn’t optimized for size and speed. In all other ways it’s ready for wide testing.

What’s missing

• Distributed transactions
• ARRAY support
• EVENTs support
• Stream BLOBs
• TRACE service
• Documentation (but you can use KInterbasDB one as FDB is as close to it as possible).
• Python 3.x support (haven’t had time to test it, but it shouldn’t be hard to make it work there)
