+- update to 4.5.1:
+  * Fixed entry_size field for result entries.
+  * The actual compression level is now once again stored in the cache entry
+  header. 
+  * Corrected error handling for unconstructible secondary storage backends. For
+  instance, this avoids a crash when a Redis server can't be reached.
+  * Made various improvements to the cache entry format. Among other things, the
+    header now contains a creation timestamp and a note of the ccache version used
+    to create the entry. The cache entry checksum has also been upgraded to use
+    128-bit XXH3 instead 64-bit XXH3.
+  * Made HTTP keep-alive configurable, defaulting to off for now.
+  * Added support for rewriting absolute path to Clang option `--gcc-toolchain`.
+  * Fixed a problem with special characters in the user info part of URLs for HTTP
+  storage.
+  * The hard link and file clone features are now disabled when secondary storage
+  is used since they only work for the local primary cache.
