-pywb 0.3.1 changelist
+pywb 0.4.0 changelist
 ~~~~~~~~~~~~~~~~~~~~~
 
+* Improved test coverage throughout the project.
+
+* live-rewrite-server: A new web server for checking rewriting rules against live content. A white-list of request headers is sent to the destination
+server. See `rewrite_live.py <https://github.com/ikreymer/pywb/blob/develop/pywb/rewrite/rewrite_live.py>`_ for more details.
+
+* Cookie Rewriting in Archival Mode: HTTP Set-Cookie header rewritten to remove Expires, rewrite Path and Domain. If Domain is used, Path is set to / to ensure cookie is visible
+from all archival urls.
+
+* Much improved handling of chunk encoded responses, better handling of zero-length chunks and fix bug where not enough gzip data was read for a full chunk to be decoded. Support for chunk-decoding w/o gzip decompression
+(for example, for binary data).
+
+* Redis CDX: Initial support for reading entire CDX 'file' from a redis key via ZRANGEBYLEX, though needs more testing.
+
+* Jinja templates: additional keyword args added to most templates for customization
+
+* Proper handling of js_ cs_ modifiers to select content-type
+
+* cdx-indexer: Support for creation of non-SURT, url-ordered as well SURT-ordered CDX files. 
+
+* Further rewrite of wombat.js: support for window.open, postMessage overrides, additional rewriting at Node creation time, better hash change detection.
+Use ``Object.defineProperty`` whenever possible to better override assignment to various JS properties.
+See `wombat.js <https://github.com/ikreymer/pywb/blob/master/pywb/static/wombat.js>`_ for more info.
+
 * Update wombat.js to support: scheme-relative urls rewriting, dom manipulation rewriting, disable web Worker api which could leak to live requests
 
 * Fixed support for empty arc/warc records. Indexed with '-', replay with '204 No Content'
