+parseCSV 0.3.2
+-----------------------------------
+Date: 1-Apr-2008
+
+This is primarily a bug-fix release for a critical
+bug which was brought to my attention.
+
+- Fixed a critical bug in conditions parsing which
+  would generate corrupt matching patterns causing
+  the condition(s) to not work at all in some
+  situations.
+
+- Fixed a small code error which would cause PHP to
+  generate a invalid offset notice when zero length
+  values were fed into the unparse() method to
+  generate CSV data from an array.
+
+Notice: If you have been using the "parsecsv-stable"
+branch as an external in any of your projects,
+please use the "stable/parsecsv" branch from this
+point on as I will eventually remove the former due
+to it's stupid naming.
+
+-----------------------------------
+
+
+parseCSV 0.3.1
+-----------------------------------
+Date: 1-Sep-2007
+
+- Small change to default output settings to
+  conform with RFC 4180 (http://rfc.net/rfc4180.html).
+  Only the LF (line feed) character was used
+  by default to separate rows, rather than
+  CRLF (carriage return & line feed).
+
+-----------------------------------
+
+
+parseCSV 0.3.0
+-----------------------------------
+Date: 9-Aug-2007
+
+- Changed to the MIT license.
+
+- Added offset and limit options.
+
+- Added SQL-like conditions for quickly
+  filtering out entries. Documentation on the
+  condition syntax is forthcoming.
+
+- Small parsing modification to comply
+  with some recent changes to the specifications
+  outlined on Wikipedia's Comma-separated values
+  article.
+
+- Minor changes and optimizations, and a few
+  spelling corrections. Oops :)
+
+- Included more complex code examples in the
+  parseCSV download.
+
+-----------------------------------
+
+
+parseCSV 0.2.1
+-----------------------------------
+Date: 8-Aug-2007
+
+- Fixed stupid code which caused auto function
+  to not work in some situations.
+
+-----------------------------------
+
+
+parseCSV 0.2.0 beta
+-----------------------------------
+Date: 2-Jan-2007
+
+- Added auto() function to automatically detect
+  delimiter character.
+  Useful for user upload incase delimiter is
+  comma (,), tab, or semi-colon (;). Some
+  versions of MS Excel for Windows use
+  semi-colons instead of commas when saving to
+  CSV files.
+  It uses a process of elimination to eliminate
+  characters that can not be the delimiter,
+  so it should work on all CSV-structured files
+  almost no matter what the delimiter is.
+
+- Generally updated some of the core workings
+  to increase performance, and offer better 
+  support for large (1MB and up) files.
+
+- Added code examples to header comment.
+
+-----------------------------------
+
+
