82 >3. What's New in this Release</A
88 > introduces IPv6 support,
89 improved keep-alive support and a bunch of minor improvements:</P
96 > Added IPv6 support. Thanks to Petr Pisar who not only provided
97 the initial patch but also helped a lot with the integration.
102 > Added client-side keep-alive support.
107 > The connection sharing code is only used if the connection-sharing
113 > The max-client-connections option has been added to restrict
114 the number of client connections below a value enforced by
115 the operating system.
120 > Fixed a regression reintroduced in 3.0.12 that could cause
121 crashes on mingw32 if header date randomization was enabled.
126 > Compressed content with extra fields couldn't be decompressed
127 and would get passed to the client unfiltered. This problem
128 has only be detected through statical analysis with clang as
129 nobody seems to be using extra fields anyway.
134 > If the server resets the Connection after sending only the headers
135 Privoxy forwards what it got to the client. Previously Privoxy
136 would deliver an error message instead.
141 > Error messages in case of connection timeouts use the right
147 > If spawning a child to handle a request fails, the client
148 gets an error message and Privoxy continues to listen for
149 new requests right away.
154 > The error messages in case of server-connection timeouts or
155 prematurely closed server connections are now template-based.
160 > If zlib support isn't compiled in, Privoxy no longer tries to
161 filter compressed content unless explicitly asked to do so.
166 > In case of connections that are denied based on ACL directives,
167 the memory used for the client IP is no longer leaked.
172 > Fixed another small memory leak if the client request times out
173 while waiting for client headers other than the request line.
178 > The client socket is kept open until the server socket has
179 been marked as unused. This should increase the chances that
180 the still-open connection will be reused for the client's next
181 request to the same destination. Note that this only matters
182 if connection-sharing is enabled.
187 > A TODO list has been added to the source tarballs to give potential
188 volunteers a better idea of what the current goals are. Donations
189 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
200 >3.1. Note to Upgraders</A
203 > A quick list of things to be aware of before upgrading from earlier
214 > The recommended way to upgrade <SPAN
217 > is to backup your old
218 configuration files, install the new ones, verify that <SPAN
222 is working correctly and finally merge back your changes using
232 > There are a number of new features in each <SPAN
236 most of them have to be explicitly enabled in the configuration
237 files. Old configuration files obviously don't do that and due
238 to syntax changes using old configuration files with a new
242 > isn't always possible anyway.
248 Note that some installers remove earlier versions completely,
249 including configuration files, therefore you should really save
250 any important configuration files!
256 On the other hand, other installers don't overwrite existing configuration
257 files, thinking you will want to do that yourself.
266 > has been merged into
275 > In the default configuration only fatal errors are logged now.
276 You can change that in the <A
277 HREF="config.html#DEBUG"
280 of the configuration file. You may also want to enable more verbose
281 logging until you verified that the new <SPAN
290 > Three other config file settings are now off by default:
292 HREF="config.html#ENABLE-REMOTE-TOGGLE"
293 >enable-remote-toggle</A
296 HREF="config.html#ENABLE-REMOTE-HTTP-TOGGLE"
297 >enable-remote-http-toggle</A
300 HREF="config.html#ENABLE-EDIT-ACTIONS"
301 >enable-edit-actions</A
303 If you use or want these, you will need to explicitly enable them, and
304 be aware of the security issues involved.
