+
+Possible amibiguity: If the user requests a range, and the file does not exist, does he want:
+1. to fill the file with zeroes, and patch the requested bytes into their correct spot; or
+2. to create the file empty, and only write the requested bytes?
+
+I will assume #1 because that plays nicely with other Things That Can Happen, such as letting the user patch the other bytes in later.

 ===========

+    - Removed the `Downloader` class after watching [this Jack Diederich talk](https://youtu.be/o9pEzgHorH0) about unecessary classes.
+    - Bytespersecond is now parsed by `bytestring.parsebytes` rather than `eval`, so you can write "100k" as opposed to "100 * 1024" etc.
+
 - 2016 07 19
     - Rearranged the big blocks to be in a logical order rather than alphabetical order. Walker > Downloader > other classes
-    - Renamed the `keep_pattern` and `remove_pattern` functions to `keep_pattern_argparse` etc to be consistent with the other functions that take argparse namespaces as their only parameter. Does not affect the commandline usage.
+    - Renamed the `keep_pattern` and `remove_pattern` functions to `keep_pattern_argparse` etc to be consistent with the other functions used by the argparser. *Does not affect the commandline usage!*
     - Gave the HTML tree divs a very gentle shadow and alternating colors to help with depth perception.
+    - Fixed some mismatched code vs comments
+    - Fixed the allowed characters parameter of `filepath_sanitize`, which was not written correctly but worked out of luck.
 
 - 2016 07 08
     - Fixed bug in which trees wouldn't generate on server:port urls.
