-------------------------------------------------------------------- ChangeLog for Privoxy -------------------------------------------------------------------- *** Since 3.0.9 Beta *** - Ordinary configuration file changes no longer cause program termination on OS/2 if the name of the logfile hasn't been changed as well. This regression probably crept in with the logging improvements in 3.0.7. Reported by Maynard. - The img-reorder filter is less likely to mess up JavaScript code in img tags. Problem and solution reported by Glenn Washburn in #2014552. - The source tar ball now includes Privoxy-Log-Parser, a syntax-highlighter for Privoxy logs. For fancy screenshots see: http://www.fabiankeil.de/sourcecode/privoxy-log-parser/ Documentation is available through perldoc(1). *** Version 3.0.9 Beta *** - Added SOCKS5 support (with address resolution done by the SOCKS5 server). Patch provided by Eric M. Hopper. - The "blocked" CGI pages include a block reason that was provided as argument to the last-applying block action. - If enable-edit-actions is disabled (the default since 3.0.7 beta) the show-status page hides the edit buttons and explains why. Previously the user would get the "this feature has been disabled" message after using the edit button. - Forbidden CONNECT requests are treated like blocks by default. The now-pointless treat-forbidden-connects-like-blocks action has been removed. - Not enabling limit-connect now allows CONNECT requests to all ports. In previous versions it would only allow CONNECT requests to port 443. Use +limit-connect{443} if you think you need the old default behaviour. - The CGI editor gets turned off after three edit requests with invalid file modification timestamps. This makes life harder for attackers who can leverage browser bugs to send fake Referers and intend to brute-force edit URLs. - Action settings for multiple patterns in the same section are shared in memory. As a result these sections take up less space (and are loaded slightly faster). Problem reported by Franz Schwartau. - Linear white space in HTTP headers will be normalized to single spaces before parsing the header's content, headers split across multiple lines get merged first. This should prevent problems like: * letting the session-cookies-only action slip some Cookies through unmodified, * only suppressing the first line of a header, thus creating an invalid one, and * to incorrectly block headers with valid timestamps that weren't properly recognized. Headers that could trigger these problems are unlikely to appear in "normal" web traffic, but could be intentionally generated to fool some of Privoxy's header parsers. - Host information is gathered outside the main thread so it's less likely to delay other incoming connections if the host is misconfigured. - New config option "hostname" to use a hostname other than the one returned by the operating system. Useful to speed-up responses for CGI requests on misconfigured systems. Requested by Max Khon. - The CGI editor supports the "disable all filters of this type" directives "-client-header-filter", "-server-header-filter", "-client-header-tagger" and "-server-header-tagger". - Fixed false-positives with the link-by-url filter and URLs that contain the pattern "/jump/". - The less-download-windows filter no longer messes "Content-Type: application/x-shockwave-flash" headers up. - In the show-url-info page's "Final results" section active and inactive actions are listed separately. Patch provided by Lee. - The GNUmakefile supports the DESTDIR variable. Patch for the install target submitted by Radoslaw Zielinski. - Embedding the content of configuration files in the show-status page is significantly faster now. For a largish action file (1 MB) a speedup of about 2450 times has been measured. This is mostly interesting if you are using large action files or regularly use Privoxy-Regression-Test while running Privoxy through Valgrind, for stock configuration files it doesn't really matter. - If zlib support is unavailable and there are content filters active but the prevent-compression action is disabled, the show-url-info page includes a warning that compression might prevent filtering. - The show-url-info page provides an OpenSearch Description that allows to access the page through browser search plugins. - Custom client-header filters that rewrite the request line incorrectly no longer cause Privoxy to crash. Reported by din_a4. - The obsolete kill-popups action has been removed as the PCRS-based popup filters can do the same and are slightly less unreliable. - The inspect-jpegs action has been removed. - The send-wafer and send-vanilla-wafer actions have been removed. They weren't particular useful and their behaviour could be emulated with add-header anyway. - Privoxy-Regression-Test has been significantly improved. - Most sections in the default.action file contain tests for Privoxy-Regression-Test to verify that they are working as intended. - Parts of Privoxy have been refactored to increase maintainability. - Building with zlib (if available) is done by default. *** Version 3.0.8 *** - Fixed a small memory leak when listen-address only specifies the port. - The source tar balls now include Privoxy-Regression-Test which (upon other things) can be used to automatically detect some packaging problems. Packagers are welcome to give it a try. - Reverted a change in 3.0.7 that caused path patterns to be checked even if the host pattern match already failed. While this doesn't noticeable affect the performance, it makes it less likely to run out of stack space with overly-complex path patterns the user might have added. - Updated the msn, yahoo and google filters to work as advertised again. - The warning message shown by the show-status CGI page is easier to understand. Previously it wasn't clear that the error message is shown below the invalid directive. (Reported by Lee) - When regenerating Content-Disposition headers the more common spelling is used for the name. Previously it was written without caps. - Less confusing log message if the content type isn't overwritten because force-text-type wasn't used but the old type doesn't look like content that would be filtered normally. - Better log messages if the user tries to execute filters that don't exist. - Treat the non-standard Request-Range headers like standard range headers and suppress them if content filtering is enabled. - Prevent the log messages for CONNECT requests to unacceptable ports from printing the limit-connect argument as [null] if limit-connect hasn't been explicitly enabled. - Don't disable the mingw32 log window if the logfile directive isn't used. While it was an intentional change in 3.0.7 at least one user perceived it as a regression and the same effect can be achieved by disabling all debug directives. - Fixed two minor problems related to the win32 build process: a css file was not being in the installer and the trustfile comment in the config.txt referenced a nonexisting file - Minor documentation fixes. *** Version 3.0.7 Beta *** - Added zlib support to filter content with gzip and deflate encoding. (Patch provided by Wil Mahan) - Dedicated filters and actions are used for header filtering. "filter-client-headers" and "filter-client-headers" are no longer supported, use server-header-filter{} and client-header-filter{} instead. - Tags can be used to change actions based on HTTP headers. - New server-header filter: less-download-windows. - New client-header taggers: css-requests, image-requests, client-ip-address, http-method, allow-post, complete-url, user-agent and privoxy-control. - New server-header taggers: content-type and privoxy-control. - The forward-override{} action allows to change the forwarding settings through the action files, for example based on client headers like the User-Agent, or the request origin. - Socks errors are no longer handled by the CGI page for DNS resolution failures. - CGI pages use favicons to signal whether they are error or control pages. This is useful if you rely heavily on browser tabs. - The show-url-info CGI page shows the forwarding settings. - "Crunch!" log messages (used when Privoxy answers requests by itself) now also contain the reason. - Allow to rewrite the request destination behind the client's back. - Fix socks requests on big-endian platforms. Patch provided by Song Weijia. - Fixes possible deadlocks and crashes on OpenBSD. Patch provided by Ralf Horstmann. - The CGI action editor allows to edit actionfiles with previously forbidden characters like dots. - New trust entries are saved with a comment that contains the trusted referring URL (Suggested by Daniel Griscom). - Filter descriptions are HTML encoded automatically. - New config option "split-large-forms" to work around a browser bug that caused IE6 and IE7 to ignore the Submit button on the edit-actions-for-url CGI page. - New config option "allow-cgi-request-crunching" to allow requests for Privoxy's CGI pages to be blocked, redirected or (un)trusted like ordinary requests. - Empty filter files no longer interrupt the filtering process prematurely and are correctly listed on the show-status CGI page. - New config option "accept-intercepted-requests" to combine Privoxy with any packet filter to build an intercepting proxy for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set). - fast-redirects{} catch redirects to https URLs as well. - redirect{s@foo@bar@} can be used to redirect to a rewritten version of the original URL. - Trap unsupported gopher proxy requests. - Fixed a bug in the User Manual delivery on Windows (mingw32 only). Images now show up correctly and HTML pages are no longer padded with garbage data. - Fixed several minor memory leaks, most of them discovered with Valgrind. - Only unlink the pidfile if it's actually used. - Retries after connection problems with forced requests aren't blocked again. - On Unix SIGABRT causes a core dump as expected and is no longer treated as normal shutdown signal. - The "access denied" CGI page is more descriptive and allows retries to circumvent the referrer check. - Updated PCRS to handle unexpected PCRE errors properly. Fixed crashes that could occur if Privoxy was build with external PCRE versions newer than Privoxy's internal one. (Reported by Chung-chieh Shan) - Fixed crashes with null bytes in PCRS replacement strings (Patch provided by Felix Gröbert). - Fixed crashes with header time randomization on mingw32. - The CGI style sheet is no longer delivered if the referring page isn't a Privoxy CGI page. This prevents a JavaScript-based Privoxy detection "attack". Note that detecting Privoxy is still possible through other ways and Privoxy was never intended to be invisible anyway. - Added support for AmigaOS 4, fixed build for AmigaOS 3.x. - The show-url-info CGI page displays a warning if Privoxy is currently toggled off. - The show-status CGI page suppresses the edit button for action files if Privoxy has no write access. - Most CGI error pages react properly to HEAD requests. - Requests with RFC 3253 HTTP methods (used by Subversion) are accepted. (Patch provided by Petr Kadlec) - New config option "templdir" to change the location of the CGI templates to make sure customized templates aren't "updated". - Better handling of "HTTP/1.1 100 Continue" responses. - The background of the PNG pattern is transparent. - Fixed XML syntax errors caused by banners-by-size and banners-by-url. - Fixed crashes and possible action file corruptions when lines containing hashes are written through the CGI editor. - Supports dynamic filters which can contain variables. - Supports tags to change the actions based on client or server headers. - Incorrect actions are logged before program termination. - The "actionsfile" syntax in the configuration file is consistent with the rest of the configuration options and requires the whole file name. This is an incompatible change, if you use an old configuration file you might have to append ".action" to your "actionsfile" directives. - With the configuration file option "enforce-blocks" the "go there anyway" mechanism can be disabled without recompiling Privoxy. - More precise error messages in case of incorrect acl syntax. - Logs a warning if filtering is enabled but impossible due to lack of zlib support or use of the prevent-compression action. - Less noisy handling of Cookie:" and "Connection:" headers. - Improved error messages in case of connection problems. - Fix a command-line-parsing bug that was introduced before 3.0.5 beta and caused Privoxy to treat the last argument as configuration file if no configuration file was specified. - Treat unknown command line options as fatal errors instead of silently ignoring them. - Use string functions with length checks more often. - Don't log CONNECT requests twice. - Allow to log the source address for ACL-related connection drops. - Don't ignore applying filters if the server didn't specify a Content-Type. Bug reported by Amuro Namie. - Rejected CONNECT requests are logged with log level info (enabled by default) and the reason for the block. - New command line option "--pre-chroot-nslookup hostname" to intialize the resolver library before chroot'ing. On some systems this reduces the number of files that must be copied into the chroot tree. (Patch provided by Stephen Gildea) - Fix a long-standing memory corruption bug that could cause Privoxy to overwrite a single byte in memory it didn't explicitly allocate (but that probably was allocated anyway due to bucket size). - Send template-based CGI pages as HTTP/1.1 unless the client asked for HTTP/1.0. - Let the first line in connection established responses end in \r\n as required by RFC1945. Reported by Bert van Leeuwen. - If no log file has been specified, disable logging instead of logging to stderr. - Don't block stderr when in daemon mode. - Ignore missing zero-chunks when filtering chunk-encoded content. Earlier Privoxy versions would buffer and then forward the content unmodified which caused some browsers to simply show empty pages. - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB. - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers action isn't being used has been removed. - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE. Reported by Lee. - Minor code clean-ups, filter and action file updates. (Some of them reported by Davide Alberani, Markus Elfring, Stefan Huehner and Adam Piggott) *** Version 3.0.6 *** - New content filters: no-ping, google, msn, yahoo and blogspot. - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html and hide-tor-exit-notation. - The special header "X-Filter: No" now disables header filtering as well. - Improved the filters img-reorder, js-annoyances, webbugs, banners-by-size, banners-by-link and ie-exploits to make them less likely to break anything. - Removed outdated URL patterns in default.action and added new ones. - Added redirection from http://p.p/user-manual to http://p.p/user-manual/ - Changed webinterface default values for hide-user-agent, hide-referrer and set-image-blocker. *** Version 3.0.5 Beta *** - Windows version can be installed/started as a service. - Windows icon stays blue when Privoxy is idle, green when busy. - Integrated Fabian Keil's extensive patch. See: http://www.fabiankeil.de/sourcecode/privoxy/. Includes the following new or significantly improved actions (among many other improvements): content-type-overwrite{} crunch-client-header{string} crunch-if-none-match crunch-server-header{string} fast-redirects{check-decoded-url} filter-client-headers filter-server-headers force-text-mode handle-as-empty-document hide-accept-language{} hide-content-disposition{} hide-if-modified-since hide-referrer{conditional-block} overwrite-last-modified{} redirect{URL} treat-forbidden-connects-like-blocks - Standard-compliant clients are prevented from displaying cached copies of Privoxy's error messages after the cause of the problem has gone. - Improved DNS error handling. - Multiple filter files can now be specified in config. - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028 with the new inspect-jpegs action. - Removed the "arbitrary" 1000 filter limit - addresses tracker #911950 - Thanks to Jindrich Makovicka for a race condition fix for the log file. The race condition remains for non-pthread implementations. Reference patch #1175720. Various other logging enhancements. - A pile of assorted bug fixes, memory leaks, enhancements, etc. - Moved Actions file reporting mechanism to SF tracker. - Two new options for config: enable-remote-http-toggle and forwarded-connect-retries. - Trap unsupported FTP requests. - Let text/xml be filtered. - Numerous updates to default.action - Increase the compiled in limit of trusted referrers from 64 to 512 (for trustfile users). *** Version 3.0.3 *** - Fixed yet another two memory leaks. Process growth seems stopped now. - Further tightened security against malicious toggle-off links. - Excluded text/plain MIME types from filtering. This fixes a couple of client-crashing, download corruption and Privoxy performance issues, whose root cause lies in web servers labelling content of unknown type as text/plain. - Assorted fixes for POSIX compliance, signal handling, graceful termination, compiler warnings, OSX support, Win32 systray, error logging, hostname wildcards, correct detection of NetBSD. - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs including the notorious "blank page" problem. - Various filter improvements; most notably the unsolicited-popups filter became less destructive - Major revamp of the actions file *** Version 3.0.2 *** - Fixed two memory leaks, one serious - Fixed bug in pcrs which could cause crashes with user-defined filters - Fixed bug in domain name matching - Assorted small fixes (Win32 menu, CGI URL editor, ..) - Added basic support for the OPTIONS and TRACE http methods - Added workaround for Bug in Mac OSX that made Privoxy crash occasionally - Refined the default action file through >400 items of user feedback - Filter changes: - Assorted refinements, optimizations and fixes in the js-annoyances, img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags, html-annoyances, content-cookies and fun filters - Replaced filter "popups" by choice between two modes: - "unsolicited-popups" tries to catch only the unsolicited ones - "all-popups" tries to kill them all (as before) - New filter "tiny-textforms" Help those tiny or hard-wrap textareas. - New filter "jumping-windows" that prevents windows from resizing and moving themselves - New filter "demoronizer" which fixes MS's abuse of std charsets (common cases anyway). - Replaced "nimda" with more general "ie-exploits" filter in which all filters for exploits shall be collected - Improved cookie logging - Rewrote make install target. Added uninstall and install-strip targets. - Fixed a potential (application-level, NOT OS-level!) security problem involving remote toggling and action file manipulation by mailicious websites. - Added ability to chroot (thanks to Sviatoslav Sviridov) - Added more action aliases for prehistoric action names - Add Slackware support to Makefile. *** Version 3.0 *** - Fixed Windows startmenu items, log window and tray icon menus. - Added warning for bogus install target - Added quicktime-kioskmode filter and improved frameset-borders - Updated default.action based on latest feedback - New PDF doc build process - Add a user contrib module to cvs: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/ijbswa/contrib/ *** Version 2.9.18 *** - Added workaround for IE bug that broke CGI interface - Bugfix: String actions now reliably editable through CGI interface - Three filters fixed (again!) - Assorted small fixes and doc enhancements *** Version 2.9.16 *** - Major revamp of default.action to get rid of years of cruft. - Same for default.filter - Re-design and major improvements to the CGI editor interface. - Address spurious 'out of memory' error due to incorrect file permissions. - Impose buffer limits while reading client and server headers. - Better memory and CPU optimization. - Add Conectiva Linux package. - user-manual directive added to config for help links from within CGI editor. - Multiple actions files can now be specified in config. - Actions files are changed to: default.action, standard.action, and user.action. user.action is for personal/local configuration. - The usual many small and miscellaneous bug and security fixes. *** Version 2.9.14 Beta *** - Fix Solaris compile problem (gateway.h and filters.h) - Makefile fixes for Solaris, FreeBSD (?) - Fix build failure where certain features were disabled. - 'blocked-compact' template is removed. Various CGI improvements, including an adaptive 'blocked' template. - Various tweaks for actions file to get ready for stable 3.0 - Included a 'Bookmarklet' and PHP scripts for reporting actions file problems via web interface at privoxy.org. Accessed via internal CGIs. - Include cgi-style.css for templates. - #include mechansim for common text in templates - Various other minor fixes. *** Version 2.9.13 Beta *** - *NEWS*: The project has been renamed to Privoxy! The new name is reflected throughout (file locations, etc). - ijb.action is now default.action. re_filterfile is now default.filter. - http://i.j.b/ is now http://p.p/ - The 'logo' option for replacing ad iamges is removed now. 'Pattern' (checkerboard) is now the default. - RPM spec file make over. *** Version 2.9.12 Beta *** - **READ**: The default listening PORT is NOW 8118!!! Changed from 8000 due to conflict with NAS (Network Audio Server, whatever that is.) - More CGI actions editor fixes and improvements. - Win32 command line fix ups. - re_filterfile now has modular sections that can be activated on a per site basis. Some new goodies there too. - +filter now takes arguments to match FILTER sections in re_filterfile for even more flexibility. - Added a new image blocker option: +image-blocker{pattern}, which displays a checkerboard patthern and scales better than the logo. - PNG images will be used in place of GIF for JB built-in images if configured with --enable-no-gif. - Clean up compiler warnings (mostly). - Improved handling of failed DNS lookups & diagnostics for failed bind to listen socket - Made --no-daemon mode log to tty instead of logfile. - Various spec file and init script cleanups and improvements (Redhat and SuSE). - CGI Editor works on OS/2 now. - Fix restart failure where sockets were in TIME_WAIT. - Fixes for actions cgi editor, make sure we have right file. - A --pidfile command line option now, in addition to --help, --version, --no-daemon, --user and configfile. --no-daemon replaces the former -d option and _DEBUG define. --user will drop privileges to the specified user. - Signal handling cleanups (*nix). - CGI actions editor improvements and fixes. - Error handling improvements, especially out of memory. - Default re_filterfile fix that caused spurious IJB logos (instead of 'blank'). - configure.in threading fixes for Solaris. - Various other minor fixes. *** Version 2.9.11 Beta Changes *** - Add "session" cookie concept where cookies exist for the life of that browser session only (ie never goes to disk). - Checks for correct header length. - Fix user:pass@host.domain.com auth bug. - Better signal handling on *nix. - Fix CFLAGS hard-coded in configure.in - Fix threading bug re: gethostbyname() that caused random URLs to fail in some cases. *** Version 2.9.11 Alpha Changes *** - A web-based editor for the actions file is included (go to http://i.j.b/). - Web-based toggle IJB on/off support. - Cookie handling has changed - the new +no-cookies-keep feature is now the default. - actionsfile is renamed to ijb.action. - junkbstr.txt is now config.txt on Win32. - Support for running IJB as a UNIX daemon process has improved. - Unix daemon now returns error code on failed start. - Timestamps in logfile and jarfile now. - Fix for the Netscape bug reintroduced in 2.9.9. - make should now abort if gmake (GNU make) not present. - Many other minor bugfixes - Start a ChangeLog :) *** Version 2.9.3 pre-Alpha Changes *** - Amiga support (completely untested by me - I don't have an Amiga) - "tinygif 3" support (redirects blocked images to a specified URL, so the browser doesn't have to load and cache many copies of the same image). - one case where there were both local and global "referrer" variables (yuck!) clarified by renaming the local one to "refer". - Fixed some places where close() was used instead of close_socket(). Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these. - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the FORCE_LOAD_PREFIX. Needs fixing properly. - Most URLs hardcoded into Junkbuster were changed to go through a script e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq The only other URLs left are the GNU GPL: http://www.fsf.org/copyleft/gpl.html and the home page: http://ijbswa.sourceforge.net/ ... and various URLs which will be intercepted by Junkbuster anyway. TODO: Still need to do something with the URLs in Junkbuster Corp's copyright/trademark notice on the bottom of the show-proxy-args page. - PCRE or GNU Regex is now a #define option. *** Version 2.9.2 pre-Alpha Changes *** - Andreas applied the latest version of the FORCE patch. *** Version 2.9.1 pre-Alpha Changes *** - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD (BTW: I think FORCE is precise enough, since loading remote data is the whole purpose of a proxy..) - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.' is more elegant and looks like a hostname in the URL, it doesn't make clear to the inexperienced user that the proxy is bypassed. It also has a higher name collision risk. - Filled in the function header templates for my functions in parsers.c (again). They obviously got lost in our current patch war ;-) - Cut the credit for the §-referrer-option from the config file, that Stefan had placed there. - Improved the re_filterfile *** Version 2.9.0 pre-Alpha Changes *** - Now use PCRE, not GNU REGEX. I have not yet had chance to check the syntax of the block/image/cookie file to ensure that they match what is expected - however they seem to work. - Replaced "configure" script with one generated by "autoconf". Also use a header "config.h" (was ijbconfig.h in my previous release) for the #defines. "config.h" is now generated with "autoheader" from "acconfig.h" and "configure.in". (Note that to install you do not need autoconf or autoheader - just run "./configure".) To see command-line options, run "./configure --help". This is my first ever autoconf script, so it has some rough edges (how PCRE is handled is the roughest). - Error logging code replaced with new module errlog.c, based on the one from JunkbusterMT (but with the threading code removed). - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not apply all of these, since I had already independently done conditional popup file, conditional image file, and integration of popup code. - ACL, Jar and trust files conditionally compiled. - New source file headers. - Various cosmetic changes. (But I have not consistently ordered the config files - I think that's worthwhile, but it's 1am and I want to get this released!) - RCS tags on .h files. - RCS tags are const char[] rather than const char *. (Saves 4 bytes per tag ;-) - VC++ project files renamed to vc_junkbuster.*. - show-proxy-args now shows status of all conditionals, not just REGEX - Various functions moved around. Most notably all the system-specific sockets code which was spread between jcc.c, bind.c, and connect.c, has been moved to "jbsockets.c". The non-system-specific code from connect.c and socks4.c has been movet to "gateway.c". Also, the config file loader and the global variables it writes to have been moved to "loadcfg.c". (Maybe this should go into loaders.c?) And candidate for the "worst filename ever" award is "miscutil.c", which contains, well, miscellaneous utility functions like zalloc. (Suggestions for a better name for this file are welcome!) - Loaders now use a common function to read a line and skip comments, and this function also stores the proxy_args. - Added ./junkbuster --help (Not for Win32 GUI) - Added ./junkbuster --version (Not for Win32 GUI) - Win32 resources are now all marked as "U.S. English", rather than being a mix of "U.S. English", "U.K. English" and "Irish English". - Version number changes to 2.9.0 ---------------------------------------------------------------------- Copyright : Written by and Copyright (C) 2001-2008 the SourceForge Privoxy team. http://www.privoxy.org/ Based on the Internet Junkbuster originally written by and Copyright (C) 1997 Anonymous Coders and Junkbusters Corporation. http://www.junkbusters.com/ This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
