The following significant problems have been reported with this version of EPICS Base:

• 2015-11-09: Another patch for Microsoft VS 2015 users, this patch is required to prevent a compiler error when building for the win32-x86 target.
• 2015-08-20: Users of the Microsoft VS 2015 compiler will need to apply this patch to Base to prevent a compiler error. Apparently only the Community Edition of this compiler works for 64-bit builds, the Express Edition exceeds a compiler limit when compiling Base.
• 2015-08-13: Some VxWorks IOC architectures have problems with the modifications made to errlog when we introduced errlogSetConsole(). This patch changes the errlog code so it doesn't expect the stderr stream from the shell that ran the startup script to remain valid for the life of the IOC.
• 2015-06-05: A possible buffer over-run was introduced into dbStaticLib with the increased size limit on link fields which can lead to memory corruption and segfaults or crashes in dbpr commands when a record has one or more long link fields. This patch resolves that issue.
• 2015-05-14: Parallel builds ("make -j") on native Windows are not working properly. Builds tend to hang (saturating one core); interrupting and running make again usually finishes the build. Limiting the number of parallel jobs using something like "make -j8" also helps prevent this problem. Sequential builds always work and are recommended for automated build environments.
• 2015-05-14: 64-bit Windows builds of the CAS library may not work with some compilers. The code in src/legacy/gdd is currently incompatible with the LLP64 model that Windows uses for its 64-bit ABI.
