ChangeLog

3.2.0 (22-11-2022)

• Fix build on Linux/macOS when only shared epics libraries exist. Although epics base always builds the static libraries along with shared libraries on Linux/macOS, some epics base packges (conda/pypi) choose to exclude static libraries to reduce package size.

• Change ca.create_context() optional argument to keyword argument. The new method signature is compatible with caffi. This change is backwards compatible.

• Support Python limited API 3.11. It is not enabled by default.

3.1.4 (20-05-2022)

• Fix ca.put() and ca.get() to accept numpy scalar number as count argument via number protocol.

• Remove deprecated function calls of PyEval_ThreadsInitialized and PyEval_InitThreads for Python 3.9+.

3.1.3 (01-10-2020)

• Fix various places where conversion exceptions are not handled.

• Improve Python 3 compatibility according to PEP 384.

3.1.2 (29-01-2019)

• Fix epicsPV defaults to wait for connection completion.

3.1.1 (07-12-2018)

• Fix compilation error on Python 3.7.

• Fix compilation error on epics base > 3.14.

• Change to use buffer object instead of numpy/c api to create numpy array.

3.1.0 (15-10-2018)

• Added class methods CaChannel.CaChannel.add_exception_event() and CaChannel.CaChannel.replace_printf_handler(). They are just thin wrapper over the low level functions ca.add_exception_event() and ca.replace_printf_handler() respectively.

3.0.4 (15-12-2017)

• Change to link EPICS dynamic libraries if environment variable EPICS_SHARED is defined.

3.0.3 (08-12-2017)

• Fix ca.put() with non-ascii input string.

• Change that it returns a bytes object from non-utf8 C string. It fails with an obscure exception message before.

• Change TravisCI to use conda-forge/linux-anvil docker image, but give the defaults channel higher priority.

3.0.2 (23-10-2017)

• Fix conda build on Linux by pinning conda-build to version 2.

3.0.1 (23-10-2017)

• Allow count=0 in ca.get() if callback is provided.

• Dereference user supplied callbacks - get/put callbacks after being called. - event callback in CaChannel.CaChannel.clear_event().

3.0.0 (06-04-2017)

• Rewrite low level ca module with the same API as in package caffi.

• Added method CaChannel.CaChannel.replace_access_rights_event()

• Added method CaChannel.CaChannel.change_connection_event()

• Added ca.ECA, ca.DBF, ca.DBR, ca.ChannelState to represent their C macros ca.ECA_XXX, ca.DBF_XXX, ca.DBR_XXX, ca.cs_xxx. For Python < 3.4, this requires module enum34.

• Changed method CaChannel.CaChannel.getw() to return string if req_type is DBR_STRING for a char waveform.

• Configure continous integration/deployment on Travis/AppVeyor.

• Drop Python 2.4 and 2.5 support.

2.4.2

• Fix chid crash on 64bit windows

• Add epics libs for python 3.5 on windows

2.4.1

• All modules are compatible with Python 2.4+ including Python 3.

• conda build recipe bundle caRepeater program in the package

2.4.0

• Add often used 3rd party module, ca_util, epicsPV and epicsMotor

• Add Anaconda build recipe

• Remove dependency of readline from Com library

2.3.0

• Support Python 3
