changes from 1.0b10 to 1.0
--------------------------

+ Don't send accept headers, as they weren't valid.
+ WARN_OLD_VERSION no longer works, until I decide what to do about it.
+ Named changed to webcheck.
+ Fixed typos in INSTALL.
+ Changes so it works with python 2.0.


changes from 1.0b9 to 1.0b10
----------------------------

b Fixed bug when server redirects to a document in robots.txt (does not show
  up as broken (hopefully))
+ Filename mangling in filelink.py to help OS/2 (and Win32) (Patch submitted
  by Steffen Siebert)
+ Added WARN_OLD_VERSION config.py option. If this option is set to true (the
  default) Linbot will check it's version number and the version numbers of
  it's plugins against a global registry on the Net. If it finds that a
  version is not the latest, it will print a warning on the reports along with
  a link you can follow to download the latest version. I think it's neat. You
  might find it annoying.
+ Added preliminary support for authenticating proxies, though it does not
  work correctly yet.
+ Added -r (redirect depth) and REDIRECT_DEPTH option in config.py to indicate
  the amount of redirects Linbot should follow when following a link. Thanks
  to Andrea Glorioso for the patch.
+ Added debugio module that handles debugging and I/O
+ Added -q (quiet option). Use it to suppress output
+ Added -d (debug) option and DEBUG_LEVEL variable in config.py for debugging
+ added version module and removed __version__ and __author__ from all the
  modules (except plugins).
b Fixed bug in Linbot using putrequest() instead of putheader() when
  requesting header information. Thanks to Andrea Glorioso for fixing this
  glitch (and Seth Chaiklin for noticing).


changes from 1.0b8 to 1.0b9
---------------------------

+ If you use the -o command-line option or the OUTPUT_DIR config file option
  and the directory does not exist, linbot will create it for you (provided
  that it has the correct permissions, etc.). Thanks to Andrea Glorioso for
  this feature.
+ Added a CREDITS file and probably left a lot of people out. If you think you
  should be in it let me know.
b Linbot will now report to the server that it can accept any MIME type (found
  in mimetypes.py. This should fix the "406: No acceptable objects found"
  error that some servers report.
b Linbot correctly identifies itself as "Linbot <version>" on HEAD requests as
  well as GET requests.


changes from 1.0b6 to 1.0b8
---------------------------

b Fixed bug when no images are reported for documents having 0 links If you
  don't know what this means it probably wasn't a problem for you.
b Fixed code that was messing with arguments passed via -x and -y and caused
  unexpected results and/or errors.
b -b flag should work this time (for real)
b Cosmetic changes (reports didn't look the way I thought they should in IE4.
  (and may not still as I haven't had a chance to check it yet)
b Linbot won't follow infinite redirects (currently hardcoded to max of 5
  redirects per document)


changes from 1.0b5 to 1.0b6
---------------------------

+ Minor change in ftplink.py should allow better ftp link checking
+ You can now press CTRL-C (or whatever your operating system supports) to
  break out of a linbot run. However, the work linbot does is not saved (yet).
b Fixed problem when server redirects a URL to itself. This fix seems to work
  for most servers I've tried but there are a few more out there that I need
  to take a look at.
b Fixed bug that caused linbot to not check for yanked URLs
+ Added -l command-line option. Usage: -l <url> where <url> is a URL pointing
  to an image to be used as the report's logo.
b "patched" strings.py so that it can better parse html files created in
   Windows/DOS (I think).
+ Made report LOGO a link to the base URL
+ httplink does not HEAD a redirected URL if it is already in the link list
  (performance improvement)
- Removed LOGO_ALT from config.py
+ Changed my email address to marduk@python.net. The official home page of
  Linbot will probably also change with the next release so stay tuned.


changes from 1.0b4 to 1.0b5
---------------------------

+ Added a contrib directory. Right now it just contains the about plugin.
  Other plugins will be included if people contribute them. Also, the man page
  will return once I have updated it. Those ugly buttons are obsolete.
+ Linbot now "inlines" stylesheets. This has the benefits of 1) better support
  of Netscape browsers (so I hear) and 2) I don't have to document to put
  linbot.css in the output directory since it grabs it from starship 8*)
b Handling of error for when robots.txt cannot be retrieved.
+ Malformed urls are trapped (sorry, I had that commented out)
b FTP link handling is totally rewritten. Fortunately it shouldn't crash
  anymore Unfortunately it doesn't really work reliably and probably never
  will. See README.ftp for details.
b Two bugs in HTTP proxy handling made it almost completely unusable, though
  conveniently seemed to cancel each other out when I was testing.
b Too many files error on large sites should be fixed. Thanks to Andrew
  Kuchling et al for suggestions.
b Bug when some servers erroneously report (or don't report) Content-Length
  header fixed.
