 HISTORY of the LZMA SDK
 -----------------------
 
+21.07          2021-12-26
+-------------------------
+- New switches: -spm and -im!{file_path} to exclude directories from processing 
+    for specified paths that don't contain path separator character at the end of path.
+- The sorting order of files in archives was slightly changed to be more consistent
+  for cases where the name of some directory is the same as the prefix part of the name
+  of another directory or file.
+
+
 21.06          2021-11-24
 -------------------------
 - Bug in LZMA encoder in file LzmaEnc.c was fixed:
