Alin Jerpelea e09aa5b7f9 Documentation: split the ReleaseNotes
Our releases contain links to github PR and lots of text so we
are splitting the release notes to individual files
This change should
- improve readability
- reduce the ReleaseNotes file for each release.

## Security Issues Fixed In This Release
Compatibility Concerns
Renamed Kconfigs
PR-5065 has renamed the following Kconfigs:
CONFIG_USER_ENTRYPOINT -> CONFIG_INIT_ENTRYPOINT
CONFIG_USERMAIN_STACKSIZE -> CONFIG_INIT_STACKSIZE
These are the non-"CONFIG_"-prefixed names:
USER_ENTRYPOINT -> INIT_ENTRYPOINT
USERMAIN_STACKSIZE -> INIT_STACKSIZE
All in-tree boards have been updated.
NuttX users developing their own out-of-tree boards need to update all references to the above names as well.
See PR-5065, git commits 4bc7b8c802cd42bd2c3d98f4fd11207d2dd50de4, 632716dc7ad04f7cad48c5787f5c0b500cbee296, and 036d98a06ba873318061380b876b838f7ffa64fb.
Changes to Build System
PR-5496 has refactored the separate Unix and Windows handling of the build variable ARCHSCRIPT so that each board's Make.defs will not need logic like this:
ifeq ($(CONFIG_CYGWIN_WINTOOL),y)
 ARCHSCRIPT = -T "${shell cygpath -w $(BOARD_DIR)$(DELIM)scripts$(DELIM)tfm-ns.ld}"
else
 ARCHSCRIPT = -T$(BOARD_DIR)$(DELIM)scripts$(DELIM)tfm-ns.ld
endif
And can instead append the variable just one, like this:
ARCHSCRIPT += $(BOARD_DIR)$(DELIM)scripts$(DELIM)tfm-ns.ld
Note the assignment is changed to append (from "=" to "+=") and removal of "-T".
All boards in the NuttX tree have been updated.
NuttX users developing their own custom boards will need to update their board's scripts/Make.defs file as shown above.
See PR-5496, git commit 855534deef50e1e9c957eb32a7b15497d1bfd34a.
PR-5712 has refactored board common logic. BOARD_SAMV7_COMMON and BOARD_STM32_COMMON options are removed and a new ARCH_BOARD_COMMON is introduced.
All in-tree boards have been updated.
NuttX users developing their own out-of-tree boards need to replace "CONFIG_BOARD_SAMV7_COMMON=y" and "CONFIG_BOARD_STM32_COMMON=y" to "CONFIG_ARCH_BOARD_COMMON=y" in defconfig files. Also for some out-of-tree boards the compilation may fail with next error messages:
make[2]: *** No rule to make target 'libboard.a'.  Stop.
Makefile:139: recipe for target 'board/libboard.a' failed
make[1]: *** [board/libboard.a] Error 2
tools/Unix.mk:509: recipe for target 'nuttx' failed
In this case the out-of-tree board actually relies on in-tree boards common folder structure. To overcome the build error there are two possible options:
Add "CONFIG_ARCH_BOARD_COMMON=y" to defconfig file (this will restore parity with previous NuttX release)
Rename "src/Make.defs" → "src/Makefile" in out-of-tree board directory and append "include $(TOPDIR)/boards/Board.mk" to "src/Makefile".
Refactored Arch Headers
PR-5720 has refactored architectural headers affecting all ARM platforms: arm_arch.h has been removed and its contents merged into arm_internal.h. Previously, most low-level modules in arch/arm/* and boards/arm/* needed to include both headers. Following the refactor, only arm_internal.h is needed.
All boards in the NuttX tree have been updated.
NuttX users developing their own custom boards will need to remove any #include "arm_arch.h" and (if necessary), #include "arm_internal.h" instead.
See PR-5720, git commit 54e630e14d7e32d6f81ae79d4e5df3d2fa787ef0.
