### Lucene 4.1 Release Highlights:
+- Lucene 4.1 has a new default codec (Lucene41Codec) based on the
+ previously-experimental "Block" indexing format for improved
+ performance, but also incorporating the functionality of "Appending"
+ and "Pulsing".
+
+- The default codec incorporates the optimization of Pulsing: terms
+ that appear in only one document (such as primary key/id fields) just
+ store the document id in the term dictionary instead of a pointer to
+ this document id in a separate file.
+
+- The default codec incorporates an efficient compressed stored fields
+ implementation that compresses chunks of documents together with LZ4.
+ (see
+ <http://blog.jpountz.net/post/33247161884/efficient-compressed-stored-fields-with-lucene>)
+
- Lucene no longer seeks when writing files (all fields are written in
an append-only way). This means it works by default with append-only
streams, hdfs, etc.

Wow, thanks Robert - those missing features were in there originally, but one of my edits accidentally deleted them, and I didn't notice…
