### SSLsplit 0.5.0 2016-03-27

-   Generically support STARTTLS through the new autossl proxyspec type that
    upgrades a TCP connection to SSL/TLS when a ClientHello message is seen
    (based on contribution by @RichardPoole42, pull req #87).
-   Add separate src/dst host and port format specifiers %S, %p, %D and %q
    to -F (pull req #74 by @AdamJacobMuller).
-   Add options -w and -W to write generated leaf key, original and forged
    certificates to disk (issue #67 by @psychomario).
-   Add signal SIGUSR1 to re-open long-living -l/-L log files (issue #52).
-   Add contributed -L log parsing scripts to extra/, including conversion to
    PCAP using emulated IP and TCP headers (contributed by @mak, issue #27).
-   Enable full-strength DHE and ECDHE by default, even for non-RSA leaf keys,
    in order to avoid weak cipher warnings from browsers (issue #119).
-   Use the same hash algorithm in signatures on forged certificates as the
    original certificates use, instead of always using SHA-1.
-   Removed all references to SHA-1 and small key RSA root CA keys from
    documentation, examples and unit testing (issue #83).
-   Introduce privilege separation architecture with privileged parent process
    and unprivileged child process; all files are now opened with the
    privileges of the user running SSLsplit; arguments to -S/-F are no longer
    relative to the chroot() if used with the -j option.
-   Filenames generated by -S and -F %d and %s changed from [host]:port to
    host,port format and using underscore instead of colon in IPv6 addresses
    in order to be NTFS clean (issue #69).
-   Connect log format: host and port are now separate fields (issues #69 #74).
-   Only initialize DNS subsystems when DNS lookups are actually needed by the
    loaded proxy specifications (related to issue #104).
-   Removed the non-standard word "unmodified" from the 2-clause BSD license.
-   Warn when an OpenSSL version mismatch is detected (issue #88).
-   Add XNU headers for OS X 10.11 El Capitan (issue #116).
-   Fix EV_READ event re-enable bug that could lead to stalled connections
    after throttling one direction (issue #109).
-   Fix build with LibreSSL that lacks recent OpenSSL API additions.
-   Fix build with OpenSSL versions that had SSLv3 support removed.
-   Fix a rare segmentation fault upon receiving EOF on the inbound connection
    while the outbound connection has not been established yet (patch by
    @eunsoopark, issue #124).
-   Fix SSL sessions to actually time out (patch by @eunsoopark, issue #115).
-   Fix passthrough mode with -t and an empty directory (issue #92).
-   Minor bugfixes and improvements.


### SSLsplit 0.4.11 2015-03-16

-   Fix build on Mac OS X 10.10.2 by improving XNU header selection.


### SSLsplit 0.4.10 2014-11-28

-   Add option -F to log to separate files with printf-style % directives,
    including process information for connections originating on the same
    system when also using -i (pull reqs #36, #53, #54, #55 by @landonf).
-   Add option -i to look up local process owning a connection for logging to
    connection log; initial support on Mac OS X (by @landonf) and FreeBSD.
-   Add option -r to force a specific SSL/TLS protocol version (issue #30).
-   Add option -R to disable specific SSL/TLS protocol versions (issue #30).
-   Disallow -u with pf proxyspecs on Mac OS X because Apple restricts
    ioctl(/dev/pf) to root even on an fd initially opened by root (issue #65).
-   Extend the certificate loading workaround for OpenSSL 1.0.0k and 1.0.1e
    also to OpenSSL 0.9.8y; fixes cert loading crash due to bug in in OpenSSL.
-   Extend Mac OS X pf support to Yosemite 10.10.1.
-   Fix startup memory leaks in key/cert loader (pull req #56 by @wjjensen).
-   Replace WANT_SSLV2_CLIENT and WANT_SSLV2_SERVER build knobs with a single
    WITH_SSLV2 build knob.
-   Minor bugfixes and improvements.


### SSLsplit 0.4.9 2014-11-03

-   Filter out HSTS response header to allow users to accept untrusted certs.
-   Build without SSLv2 support by default (issue #26).
-   Add primary group override (-m) when dropping privileges to an
    unprivileged user (pull req #35 by @landonf).
-   Support pf on Mac OS X 10.10 Yosemite and fix segmentation fault if
    no NAT engine is available (pull req #32 by @landonf).
-   Support DESTDIR and MANDIR in the build (pull req #34 by @swills).
-   No longer chroot() to /var/empty by default if run by root, in order to
    prevent breaking -S and sni proxyspecs (issue #21).
-   Load -t certificates before dropping privileges (issues #19 and #20).
-   Fix segmentation fault when using -t without a CA.
-   Minor bugfixes and improvements.

-   Also build ipfw NAT engine if pf is detected to support pf divert-to.
-   Unit tests (make test) no longer require Internet connectivity.
-   Always use SSL_MODE_RELEASE_BUFFERS when available, which lowers the per
    connection memory footprint significantly when using OpenSSL 1.0.0+.
-   Fix memory corruption after the certificate in the cache had to be updated
    during connection setup (issue #16).
-   Fix file descriptor leak in passthrough mode (-P) after SSL errors.
-   Fix OpenSSL data structures memory leak on certificate forgery.
