-### Reduce symbol and macro pollution from epicsAtomic.h on WIN32
-
-`epicsAtomic.h` no longer pulls in as many unneeded declarations and macros from
-`windows.h`. Prior to this change, including `epicsAtomic.h` at the wrong time
-could result in unexpected compiler errors. Due to the nature of `windows.h`,
-some unneeded declarations are still pulled in, however the number is greatly reduced.
-Code that needs these declarations should explicitly include `windows.h` before `epicsAtomic.h`.
-
+=======
 ### epicsExport simplifications
 
 `epicsExportAddress()`, `epicsExportRegistrar()` and `epicsRegisterFunction()`
-no longer require to be wrapped in `extern "C" { }` in C++ code.
+no loger require to be wrapped in `extern "C" { }` in C++ code.
 
-### New `dbServerStats()` API for iocStats
-
-A new routine provides the ability to request channel and client counts from
-named server layers that implement the `stats()` method, or to get a summary
-of the counts from all registered server layers. A preprocessor macro
-`HAS_DBSERVER_STATS` macro is defined in the `dbServer.h` header file to
-simplify code that needs to support older versions of Base as well.
