- OCI_GetSQLVerb() handles some new verbs added with Oracle 21c
- OCI_Execute() and related methods return now FALSE and report an OCI_Error for PL/SQL statements raising PL/SQL no_data_found exceptions
* This revert behavior introduced in v4.3.1 for addressing issue #68
* Motivation is to re-align on SQL*Plus behavior
- OCI_GetOCIRuntimeVersion() and OCI_GetOCICompileVersion() returned integer values on 6 digits instead of 4 digits
* Handles now minor version using 2 digits (e.g. Oracle OCI version 19.16.0)
* Use macros OCI_VER_MAJ, OCI_VER_MIN, OCI_VER_REV and OCI_VER_MAKE to do computations on versions
- Very old Oracle OCI 8.0.x is now supported
- Up to now, OCILIB supported all Oracle versions from 8.1
- Oracle 8.0 is now also supported for very old legacy systems (as Oracle 8.0 was released in mid 90's)
- As OCI multi-threaded APIs were only available from 8.1, passing OCI_ENV_THREADED to OCI_Initialize() with Oracle 8.0 will generate an error:
- OCILIB Error code : OCI_ERR_NOT_AVAILABLE
- OCILIB Error message : "Feature not available (Oracle 8.1 multihreading support)"

### Fixes (C++ API)
- Issue 250: Exception handling when using OCI_CHARSET_WIDE
- Issue 262: Using correct delete[] in ManagedBuffer destructor
- Updated compilers for MS Windows prebuilt binaries
* VS2019 16.9.0 for 32/64 bit DLLs
* VC runtime (statically linked) updated from vc141_xp to vc142
* Note: Windows XP is not supported anymore due to the runtime update
- Reduced some ocilib structures size by removing some paddings (especially in 64bits)
- Added a makefile to build the C++ demo (Makefile_demo_cpp) that is also now installed with the C demo Makefile
- OCILIB Test suite is now ported to Linux/Unix platforms
* Test suite is now provided in ocilib-x.y.z-gnu.tar.gz distribution archives and installed by 'make install' among documentation and demo (typically in /usr/local/share/doc/ocilib/tests)
* To build the test suite:
- Modify the db credentials in ocilib_tests.h
- Use Makefile_tests (it depends on google test that must be installed prior building the test suite)

]]> - OCILIB internal and public symbols management
* For static library:
- All private symbols that can have local scope are now declared static
- All private non static symbols are now prefixed with "Ocilib" to avoid collisions
* For shared library:
- No change for Windows platform as __declspec(dllimport) and __declspec(dllexport) were already handled
- When using GNUC compatible compiler:
- all public symbols are now declared with __attribute__ ((visibility ("default")))
- all private symbols are now delcared with __attribute__ ((visibility ("hidden")))
- Configure script will automatically add the compiler flag "-fvisibility=hidden"
- OCILIB compiles now without any warnings when using GNUC with flags -Wall -Wextra -pedantic
- Issue 242: Fixed strings.h conflict with recent GCC versions
- Issue 243 : Fixed compiling ocilib directly from repository on non Windows systems (while using distribution archive was OK)
- Issue 245 : Fixed ocilib shared library symbols visibility (Linux/Unix)
- Removed useless old macros for mapping lib C string function to ansi or wide char versions (ostrXXX)
- Removed symbols ocisprintf(), ocistrdup(), ocistrcasecmp(), ociwcsdup(), ociwcscasecmp() from OCILIB shared library
- Updated compilers for MS Windows prebuilt binaries
* VS2019 16.7.6 for 32/64 bit DLLs <br/>

]]> - Library internal design changes (preparing v5.0.0)
* OCILIB code base has been layered in 2 distinct API layers:
- Internal API that has now its own separate design
- v4.7.0 internal API, while matching the public one in this version, has most of its methods renamed
- It will evolve differently, preparing new public APIs for future versions
- Public APIs exposing features to clients
- v4.7.0 is exposing the same public API as previous versions
- v5.0.0 will expose a different API
- Both will use same internal API
- Contextual error management enhancements
- As internal APIs cannot be called from outside the library, last error management has been simplified and improved
- Enhancements on internal methods implementation:
- Since v3.0.0 (back in 2008), OCILIB methods implementations are standardized to follow the same single exit point pattern
- Standardized entry point checks and exit points are based on extentive macros usage
- But the control flow was handled by a status variable leading to continuous and nested checks
- With 4.7.0, no more "if (STATUS) {...}" in the code.
- Instead, in case of errors, code directly jumps to exit points that can have cleanup code sections.
- See it as try {...} finally{...}
- Thus, code is now very sequential, much easier to read, with no nested error management/branching.
- Public headers reorganization:
* Broke up ocilib.h content into multiple headers located in /include/ocilibc/
* Broke up C++ headers content into multiple headers located in /include/ocilibcpp/
- Enhanced Error handing:
* Updated OCI_Cleanup(): if there are any unfreed allocated bytes by the library itself (e.g. OCILIB user objects not freed)
- it raises an error of type OCI_ERR_UNFREED_BYTES (with the amount of bytes in the error message)
- it completes cleanup and returns FALSE
* Added method OCI_ErrorGetLocation() to return the method name where the exception occured
* Updated method OCI_ErrorGetString() to return a string using the following format "Error occured at {Location}: {Description}"
- Issue 239: Fetching nclobs as strings return value in hexa format truncated values when nsl_lang is UTF8
- Issue 238: Fetching clobs as strings return truncated values when nsl_lang is UTF8
- Issue 236: Memory issue with OCI_BAM_INTERNAL and OCI_CDT_NUMERIC
- Fixed OCI_EnqueuePut() and OCI_DequeueGet() in OCI_CHARSET_WIDE charset mode (added a workaround for a known oracle client UTF16 bug)
- Fixed a minor memory leak when using implicit resultsets
- Issue 230: Memory leaks while rebinding vectors
- Extended C API Test suite that has now a much wider coverage
