//=== Removed Dissectors

=== New File Format Decoding Support

Wireshark is able to display the format of some types of files (rather than
displaying the contents of those files). This is useful when you're curious
about, or debugging, a file and its format.  To open a capture file (such as
PCAP) in this mode specify "MIME Files Format" as the file's format in the
Open File dialog.

New files that Wireshark can open in this mode include:

--sort-and-group--
BTSNOOP
PCAP
PCAPNG
--sort-and-group--

//--sort-and-group--

=== Major API Changes

The libwireshark API has undergone some major changes:

* The emem framework (including all ep_ and se_ memory allocation routines) has
been completely removed in favour of wmem which is now fully mature.
* The (long-since-broken) Python bindings support has been removed.  If
you want to write dissectors in something other than C, use Lua.
* Plugins can now create GUI menu items.
* Heuristic dissectors can now be globally enabled/disabled so
heur_dissector_add() has a few more parameters to make that possible
* proto_tree_add_text has been removed.
* tvb_length() has been removed in favor of tvb_reported_length() and
tvb_captured_length().
* The API for RPC-based dissectors has changed significantly: the procedure
dissectors no longer take an offset, void-argument procedures now need to be
declared with a function (use dissect_rpc_void()), and rpc_init_prog()
now handles procedure registration too (it takes additional arguments to
handle this; rpc_init_proc_table() was removed).

== Getting Wireshark

Wireshark source code and installation packages are available from
https://www.wireshark.org/download.html.

=== Vendor-supplied Packages

Most Linux and Unix vendors supply their own Wireshark packages. You can
usually install or upgrade Wireshark using the package management system
specific to that platform. A list of third-party packages can be found
on the https://www.wireshark.org/download.html#thirdparty[download page]
on the Wireshark web site.

== File Locations

Wireshark and TShark look in several different locations for preference
files, plugins, SNMP MIBS, and RADIUS dictionaries. These locations vary
from platform to platform. You can use About→Folders to find the default
locations on your system.

== Known Problems

Dumpcap might not quit if Wireshark or TShark crashes.
(ws-buglink:1419[])

The BER dissector might infinitely loop.
(ws-buglink:1516[])

Capture filters aren't applied when capturing from named pipes.
(ws-buglink:1814[])

Filtering tshark captures with read filters (-R) no longer works.
(ws-buglink:2234[])

Resolving (ws-buglink:9044[]) reopens (ws-buglink:3528[]) so that Wireshark
no longer automatically decodes gzip data when following a TCP stream.

Application crash when changing real-time option.
(ws-buglink:4035[])

Hex pane display issue after startup.
(ws-buglink:4056[])

Packet list rows are oversized.
(ws-buglink:4357[])

Wireshark and TShark will display incorrect delta times in some cases.
(ws-buglink:4985[])

The 64-bit version of Wireshark will leak memory on Windows when the display
depth is set to 16 bits (ws-buglink:9914[])

Wireshark should let you work with multiple capture files. (ws-buglink:10488[])
