 COFF Improvements
 -----------------
 
-* /linkrepro: now takes the filename of the tar archive it writes, instead
-  of the name of a directory that a file called "repro.tar" is created in,
-  matching the behavior of ELF lld.
-* The new `/lldignoreenv` flag makes lld-link ignore environment variables
-  like `%LIB%`.
 * ...
 
 MinGW Improvements
