- Fixed a DoS issue in case of client requests with incorrect
- chunk-encoded body. When compiled with assertions enabled
- (the default) they could previously cause Privoxy to abort().
- Reported by Matthew Daley.
+ Fixed memory leaks when a response is buffered and the buffer
+ limit is reached or Privoxy is running out of memory.

- Fixed multiple segmentation faults and memory leaks in the
- pcrs code. This fix also increases the chances that an invalid
- pcrs command is rejected as such. Previously some invalid commands
- would be loaded without error. Note that Privoxy's pcrs sources
- (action and filter files) are considered trustworthy input and
- should not be writable by untrusted third-parties.
+ Fixes a memory leak when client tags are active.

- If a pcrs command is rejected as invalid, Privoxy now logs
- the cause of the problem as text. Previously the pcrs error
- code was logged.
+ Added experimental https inspection support which allows to filter
+ https traffic. To enable it, install MbedTLS and configure with
+ --with-mbedtls, or install OpenSSL or LibreSSL and configure
+ with --with-openssl.
+ Afterwards configure the directives in section 7 of the
+ config file and enable the +https-inspection action.
+ Initial MbedTLS-based code contributed by Vaclav Svec,
+ initial OpenSSL support contributed by Maxim Antonov.
