+21 June 2007 - 2.5.0-dev2
+-------------------------
+
+ * Reversioned from 2.2.0 base version to 2.5.0 because of the large changeset.
+
+ * Added @within string comparison operator with support for macro expansion.
+
+ * Removed experimental variable RESPONSE_CONTENT_ENCODING which was not
+   working as intended.
+
+ * Update included core rules to latest version.
+
+ * Do not trigger "pause" action for internal requests.
+
+ * Added matching rule filename and line number to audit log.
+
+ * Added new phrase matching operators, @pm and @pmFromFile.  These use
+   an alternate set based matching engine (Aho-Corasick) to perform faster
+   phrase type matches such as black/white lists, spam keywords, etc.
+
+ * Cache transformations per-request/phase so they are not repeated.
+
+ * Fixed issue with requests that use internal requests.  These had the
+   potential to be intercepted incorrectly when other Apache httpd modules
+   that used internal requests were used with mod_security.
+
+ * Added Solaris to the list of platforms not supporting the hidden
+   visibility attribute.
+
+ * Removed excessive debug log entries about "capture" action.
+
+ * Fixed decoding full-width unicode in t:urlDecodeUni.
+
+ * Lessen some overhead of debugging messages and calculations 
+
+ * Removed strnlen() calls for non-GNU platforms.

+ * Fixed decoding full-width unicode in t:urlDecodeUni.
+
+ * Lessen some overhead of debugging messages and calculations.
+
+ * Do not try to intercept a request after a failed rule.  This fixes the
+   issue associated with an "Internal Error: Asked to intercept request
+   but was_intercepted is zero" error message.
+
+ * Added SecAuditLog2 directive to allow redundent concurrent audit log
+   index files.  This will allow sending audit data to two consoles, etc.
+
+ * Small performance improvement in memory management for rule execution.

-
+- 960911 - Invalid HTTP request line
-Fixed regular expresion in rule 960010 (file #30) to allow mulipart-data content

+Regular expressions fixes:
-New events:
+- Further optimization of some regular expressions (using the non-greediness operator)
-- 960037  Directory is restricted by policy
+
-- 960038  HTTP header is restricted by policy
+------------------------
-
+version 1.4 - 2007/05/02
-Regular expressions fixes:
+------------------------
-- Regular expressions with @ at end of beginning (for example "@import)
+
-- Regular expressions with un-escaped "."
+New Events:
-- Command Injections now always require certain characters both before and after the command. Important since many are common English words (finger, mail)
+- 970021 - WebLogic information disclosure
-- The command injection wget is not searched in the UA header as it has different meaning there.
+    Matching of "<title>JSP compile error</title>" in the response body, will trigger this rule, with severity 4 (Warning)
-- LDAP Fixed to reduce FPs:
+- 950015,950910,950911 - HTTP Response Splitting
-	+ More accurate regular expressions
+    Looking for HTTP Response Splitting patterns as described in Amit Klein's excellent article:
-	+ high bit characters not accpeted between signature tokens.
+    http://www.packetstormsecurity.org/papers/general/whitepaper_httpresponse.pdf
-- Do not detect <?xml as a PHP tag in both PHP injection and PHP source leakage
+ModSecurity does not support compressed content at the moment. Thus, the following rules have been added:
-- Removed Java from automation UA
+- 960902 - Content-Encoding in request not supported
-- When validating encoding, added regexp based chained rule that accepts both %xx and %uxxxxx encoding bypassing a limitation of "@validateUrlEncoding"
+    Any incoming compressed request will be denied
-
+- 960903 - Content-Encoding in response not suppoted
-Additional rules logic:
+    An outgoing compressed response will be logged to alert, but ONLY ONCE.
-- Checks for empty headers in addition to missing ones  (Host, Accept and User-Agent)
+
-- OPTIONS method does not require an accept header.
+False Positives Fixes:
-- Apache keep alive request exception.
+- Removed <.exe>,<.shtml> from restricted extensions
-- PROPFIND and OPTIONS can be used without content-encoding (like HEAD and GET)
+- Will not be looking for SQL Injection signatures <root@>,<coalesce> in the Via request header
-- Validate byte range checks by default only that no NULL char exists.
+- Excluded Referer header from SQL injection, XSS and command injection rules
-- Added CSS to allowed extensions in strict rule sets.
+- Excluded X-OS-Prefs header from command injection rule
-- Changed default action in file #50 to pass instead of deny.
+- Will be looking for command injection signatures in
-- Moved IP host header from protocol violations to protocol anomalies.
+  REQUEST_COOKIES|REQUEST_COOKIES_NAMES instead of REQUEST_HEADERS:Cookie.
-
+- Allowing charset specification in the <application/x-www-form-urlencoded> Content-Type
-Modified descriptions: 
+
-- 950107: URL Encoding Abuse Attack Attempt
+Additional rules logic:
-- 950801: UTF8 Encoding Abuse Attack Attempt
+- Corrected match of OPTIONS method in event 960015
-- Added matched pattern in many events using capture and %{TX.0}
+- Changed location for event 960014 (proxy access) to REQUEST_URI_RAW
-- Added ctl:auditLogParts=+E for outbound events and attacks to collect response.
+- Moved all rules apart from method inspection from phase 1 to phase 2 -
-
+    This will enable viewing content if such a rule triggers as well as setting
---
+    exceptions using Apache scope tags.
-Version 1.2 - 2006/11/19
+- Added match for double quote in addition to single quote for <or x=x> signature (SQL Injection)
-
+- Added 1=1 signature (SQL Injection)
-Changes:
