PyKX 3.0.0

Release Date: 2024-11-12

  • Removal of various deprecated keywords used in table operations:

    • modify keyword for select, exec, update and delete operations on pykx.Table and pykx.KeyedTable. This has been permanently changed to use inplace.
    • replace_self keyword when attempting to overwrite a pykx.Table or KeyedTable using insert/upsert functionality. This has been permanently changed to use inplace.

  • The following table outlines environment variables/configuration options which are now fully deprecated and the updated name for these values if they exist.

PyKX 2.5.0

Release Date: 2024-05-15

  • Deprecated .pd(raw_guids) keyword.
  • Renamed labels parameter in Table.rename() to mapper to match Pandas. Added deprecation warning to labels.
  • Deprecation of type column in dtypes output as it is a reserved keyword. Use new datatypes column instead.

PyKX 2.3.1

Release Date: 2024-02-07

  • To align with other areas of PyKX the upsert and insert methods for PyKX tables and keyed tables now support the keyword argument inplace, this change will deprecate usage of replace_self with the next major release of PyKX.

PyKX 2.2.1

Release Date: 2023-11-30

  • Deprecation of internally used environment variable UNDER_PYTHON which has been replaced by PYKX_UNDER_PYTHON to align with other internally used environment variables.
  • Addition of deprecation warning for environmental configuration option PYKX_NO_SIGINT which is to be replaced by PYKX_NO_SIGNAL. This is used when users require no signal handling logic overwrites and now covers SIGTERM, SIGINT, SIGABRT signals amongst others.

PyKX 1.6.1

Release Date: 2023-07-19

  • Added deprecation warning around the discontinuing of support for Python 3.7.

PyKX 1.0.1

Release Date: 2022-03-18

  • The sync parameter for pykx.QConnection and pykx.QConnection.__call__ has been renamed to the less confusing name wait. The sync parameter remains, but its usage will result in a DeprecationWarning being emitted. The sync parameter will be removed in a future version.

PyKX 1.0.0

Release Date: 2022-02-14

  • The pykdb.q.ipc attribute has been removed. The IPC module can be accessed directly instead at pykx.ipc, but generally one will only need to access the QConnection class, which can be accessed at the top-level: pykx.QConnection.
  • The pykdb.q.K attribute has been removed. Instead, K types can be used as constructors for that type by leveraging the toq module. For example, instead of pykdb.q.K(x) one should write pykx.K(x). Instead of pykx.q.K(x, k_type=pykx.k.SymbolAtom) one should write pykx.SymbolAtom(x) or pykx.toq(x, ktype=pykx.SymbolAtom).
  • Most KdbError/QError subclasses have been removed, as identifying them is error prone, and we are unable to provide helpful error messages for most of them.
  • The pykx.kdb singleton class has been removed.
