+Major feature/bugfix release of UniversalCodeGrep (ucg).
 
 ### New Features
+- 20-30% faster than ucg 0.2.2 on most benchmarks.
 - New file inclusion/exclusion options:
 	- `ack`-style `--ignore-file=FILTER:FILTERARGS`: Files matching FILTER:FILTERARGS (e.g. "ext:txt,cpp") will be ignored.
 	- `grep`-style `--include=GLOB`: Only files matching GLOB will be searched.
 	- `grep`-style `--exclude=GLOB`: Files matching GLOB will be ignored.
 	- `ag`-style `--ignore=GLOB`: Files matching GLOB will be ignored.  Note that unlike `ag`'s option, this does not apply to directories).
 - Files and directories specified on the command line (including hidden files) are now scanned regardless of ignore settings, and in the case of files, whether they are recognized as text files.
-- `--TYPE`- and `--noTYPE`-style options now support unique-prefix matching.  E.g., `--py`, `--pyth`, and `--python` all select the Python file type.   
-- OSX and PC-BSD now supported.
+- `--TYPE`- and `--noTYPE`-style options now support unique-prefix matching.  E.g., `--py`, `--pyth`, and `--python` all select the Python file type.
+- New file type filter: `glob`.  E.g. '--type-set=mk:glob:?akefile*'.
+- OS X and some *BSDs now supported.  Builds and runs on Xcode 6.1/OS X 10.9 through Xcode 8gm/OS X 10.11. 
 - Now compiles and links with either or both of libpcre and libpcre2, if available.  Defaults to using libpcre2 for matching.
 - Directory tree traversal now uses more than one thread (two by default).  Can be overridden with new "--dirjobs" command-line parameter.  Overall performance improvement on all platforms vs. 0.2.2 (e.g., ~25% on Fedora 23 with hot cache).
 - New portable function multiversioning infrastructure.  Currently used by the following features:
@@ -24,8 +28,8 @@
 - Scanner threads now use a reusable buffer when reading in files, reducing memory allocations by ~10% (and ~40% fewer bytes allocated) compared to version 0.2.2.
 - Refactored FileScanner to be a base class with derived classes handling the particulars of using libpcre or libpcre2 to do the scanning. 
 - Added a basic diagnostic/debug logging facility.
-- ResizableArray now aligns allocations to 64-byte boundaries to match Core i7 cache line sizes in an effort to prevent false sharing.
-- Performance/Benchmarking infrastructure and test expansion and improvements.
+- ResizableArray now takes an alignment parameter.  File buffer allocations are now done on max(ST_BLKSIZE,128k)-byte boundaries.

 ### Fixed
 - Cygwin now requires AC_USE_SYSTEM_EXTENSIONS for access to get_current_dir_name().  Resolves #76.

 - Resolved segfaults on some systems due to dirname() modifying its parameter.  Resolves #96.
 - No longer treating PCRE2 reporting no JIT support as an error.  Resolves #100.
