-    Do not update StoreEntry expiration after errorAppendEntry() (#1580)
-    
-    errorAppendEntry() is responsible for setting entry expiration times,
-    which it does by calling StoreEntry::storeErrorResponse() that calls
-    StoreEntry::negativeCache().
-    
-    This change was triggered by a vulnerability report by Joshua Rogers at
-    https://megamansec.github.io/Squid-Security-Audit/cache-uaf.html where
-    it was filed as "Use-After-Free in Cache Manager Errors". The reported
-    "use after free" vulnerability was unknowingly addressed by 2022 commit
-    1fa761a that removed excessively long "reentrant" store_client calls
-    responsible for the disappearance of the properly locked StoreEntry in
-    this (and probably other) contexts.

-Subject: [PATCH 1/6] Ignore whitespace chars after chunk-size
-
-Previously (before #1498 change), squid was accepting TE-chunked replies
-with whitespaces after chunk-size and missing chunk-ext data. After
-
-It turned out that replies with such whitespace chars are pretty
-common and other webservers which can act as forward proxies (e.g.
-nginx, httpd...) are accepting them.
-
-This change will allow to proxy chunked responses from origin server,
-which had whitespaces inbetween chunk-size and CRLF.

-which set of whitespaces characters will be parsed. If wsp_only is set

-
-Also optimized number of ParseBws calls.

-Subject: [PATCH 4/6] Bug 5449 is a regression of Bug 4492!
-
-Both bugs deal with "chunk-size SP+ CRLF" use cases. Bug 4492 had _two_
-spaces after chunk-size, which answers one of the PR review questions:
-Should we skip just one space? No, we should not.
-
-The lines moved around in many commits, but I believe this regression
-was introduced in commit 951013d0 because that commit stopped consuming
-partially parsed chunk-ext sequences. That consumption was wrong, but it
-had a positive side effect -- fixing Bug 4492...
