- Use a Sphinx/Myst {include} directive to pull the text from all previous
RELEASE files into the output, which makes the website sidebar index work
properly.
- Exclude the RELEASE files from the files given to RTD to publish, they
aren't needed now and generate warnings if included.
- Updated the intro paragraph in all RELEASE files.

Release Notes
This document describes the changes that were included in the release of EPICS noted below. Release entries are now provided in a separate document for each version in the EPICS 7 series, but all are combined into a single page for publishing on the EPICS website. Separate release documents are also included from the older Base 3.15 and 3.16 series.
The external PVA submodules continue to maintain their own release notes files as before, but the entries describing changes in those submodules since version 7.0.5 have been copied into the associated EPICS Release Notes files, and will be added to new EPICS Release Notes published in the future.
EPICS Release 7.0.8.1
Limit to _FORTIFY_SOURCE=2
GCC versions 12 and beyond and glibc have added some aggressive runtime
checks for buffer overflows in libc functions at runtime, and the
Ubuntu 2024.04 release
increased their default gcc fortification level from 2 to 3.
This has started causing EPICS Base builds to fail on that version, and
other OS releases may make that configuration change with similar results.
This release detects a compiler configured with _FORTIFY_SOURCE=3 and
overrides it to 2.
Later releases of Base will adjust the code, providing information to the
compiler to avoid triggering these incorrect protections.
Fix issue with compress record
In Base 7.0.8, an update to the compress record was added to allow for certain algorithms to use partially filled buffers in their computations. Unfortunately, this broke the behaviour of the records in certain cases. This has been fixed.
Various minor changes
These included fixing minor memory leaks and documentation corrections. The
SIZV field of lsi, lso and printf record VAL fields now can't exceed 32767
characters, to match an internal limit.
epicsSocketAccept() now returns SOCKET, not int
This might have some effect on downstream modules still using int, but the
OS-specific osdSock.h headers which osiSock.h includes have all declared
SOCKET (in most casese as a typedef for int) for many releases.
This change removes a compiler warning on WIN32.
Further details and the discussion about this change can be found
here.
dbLoadRecords allows macros with default values
Previously the parser assumed that files containing macro substitutions were bad if no macro definitions were provided; that assumption was made incorrect once macro substitutions were allowed to provide a default value.
Hostname length limit in CA removed
Before this release, the CA client library only handled hostnames in address list environment variables up to 255 characters long. This limit has been removed.
