09.03.2015: SP Stack Kernel 742 PL#100 Released
SP stack kernel 742 PL #100 is now available on SAP Support Portal. It contains various improvements and enhancements that are outlined in detail in Note 2136550.
Information on known issues in the stack kernel 742 PL #100 can be found in Note 2129327. This note will be updated on regular basis.
04.03.2015: SP Stack Kernel 721 PL#401 Revoked
SP Stack kernel 721 PL #401 has been revoked from SAP Support Portal for all platforms except for MS Windows because the kernel archives contained some files with wrong versions.
In most cases it is not necessary to replace the kernel in a system running with PL#401 because the issue has a limited impact and does not affect the kernel itself. Details are outlined in Note 2138260.
SP stack kernel PL#402 will be released as soon as possible; this document will be updated accordingly.
06.02.2015: SP Stack Kernel 741 PL#200 Released

For a summary of enhancements and improvements included into this stack kernel, see SAP Note 2101802 - SAP Support Package Stack Kernel 7.41 Patch Level 200.
30.01.2015: SP Stack Kernel 721 PL#401 replaces PL#400
Current SP stack kernel 721 PL#400 has been replaced with PL#401, see Note 2121693 - SAP Support Package Stack Kernel 7.21 (EXT) Patch Level 401.
It fixes a file permission issue that has a very limited impact:
- It occurs with 721_EXT kernel on Windows platforms only
- It has no effect at runtime, only for future system maintenance
- Workaround is easy
This means: even if above criteria apply, it is not always necessary to replace already installed 721 kernel PL#400. Refer to Note 2118382 for more information.
