2026-04-17  Xu Huang  <huang@par-tec.com>

	* New: Increase ABI minor version. New ABI version: 5.1.

	* New: Macro `PSCOM_API_VERSION` provides numeric pscom API version;
	Additional macros with post-fixes `_MAJOR`,`_MINOR`, and `_PATCH` provide
	the sub-parts of the API version.

	* New: Function `pscom_get_version` to get pscom API and ABI versions incl.
	CUDA support at runtime.

2026-02-02  Sonja Happ  <sonja.happ@par-tec.com>	-	6.1.0-0rc1

2026-01-07  Sonja Happ  <sonja.happ@par-tec.com>

	* New: Resend mechanism for RRComm precon to handle errors obtained
	from RRC_recvX during connection establishment via RRComm.

	`pscom_resume_listen` and `pscom_suspend_listen` might be removed from the
	API in a future release.

	pscom's profiling feature during compile time.

2024-12-03  Sonja Happ  <sonja.happ@par-tec.com>

	In addition, some logging aspects might be raised:
	PSP_DEBUG_VERSION=1     Show the pscom version (info)
	PSP_DEBUG_CONTYPE=1     Show connection types (was PSP_DEBUG>=1, now
                                PSP_DEBUG>=3 (info) or PSP_DEBUG_CONTYPE=1)
	PSP_DEBUG_SUSPEND=1 or 2 Show suspend info/debug
