As this is a restricted server I can not verify if the warning is valid or
not.

2.5.STABLE4-20040123 should be identical to your previous sources. There
has been no changes after the keep-alive.patch (2004-01-19).

Cronological history of recent Squid-2.5 changes:

2004-01-19 18:46 hno

* src/HttpMsg.c: Spelling correction

2004-01-19 18:34 hno

* src/HttpMsg.c: Bug #890: Various HTTP workarounds and minor
  corrections

  Squid is still HTTP/1.0 so we can not assume a HTTP/1.1 message
  indicates persistent connections.

2004-01-15 08:43 hno

* src/acl.c: Corrected debug level in detection of empty
  proxy_auth acls

2004-01-15 08:40 hno

* src/acl.c: Refuse to accept empty proxy_auth acl declarations. In
  combination with the splay_splay unpredictability on empty splay
  trees this could give very strange results.

2004-01-15 08:38 hno

* lib/splay.c: Make splay_splay predictable if called on empty
  splay trees.

2004-01-14 19:47 hno

* src/: http.c, structs.h: Bug #890: Some servers send broken
  keep-alive headers (IIS-5)

  The initial patch was not a little to broad and claimed fully
  valid body-less replies violated keep-alive. (304, HEAD etc)

2004-01-12 11:51 hno

* src/: client_side.c, http.c, structs.h: Bug #890: Various HTTP
  workarounds and minor corrections

  - Automatically time out incorrectly signalled persistent
    connections after 10 seconds of inactitivy. Also gives a warning
    in cache.log
