Changed Functionality
---------------------
- Logging of failed analyzers has been overhauled. `dpd.log` was replaced
by a new `analyzer.log` that presents a more unified and consistent view
of failed analyzers. The previous `analyzer.log` was renamed to `analyzer-debug.log`;
see below for more details.
For protocol analyzers, `analyzer.log` now reports initially confirmed analyzers that
Zeek subsequently removed from the connection due to a protocol violation.
For file and packet analyzers, all errors will be logged to `analyzer.log`.
As part of this work, a new `analyzer_failed` event has been introduced. This event
is raised when an analyzer is removed because of raising a violation.
- `analyzer.log` was renamed to `analyzer_debug.log`, and is no longer created
by default. The log file will be created if the `frameworks/analyzer/debug-logging.zeek`
policy script is loaded.
Note that the namespace for options in the script changed to
`Analyzer::DebugLogging`. Furthermore the default options changed to enable
more detailed output by default.
- Publishing remote events with vector arguments that contain holes is now

holes would have been. There's a chance this breaks scripts that accidentally

``WebSocketServerOptions`` was deprecated. Use the new ``$listen_addr`` field
instead.
- The `service_violation` field of the connection record was marked as deprecated.
Consider using the new `failed_analyzers` field of the connection record instead.
- `detect-protocol.zeek was the last non-deprecated policy script left in
`frameworks/dpd`. It was moved to `frameworks/analyzer/detect-protocol.zeek`.

Deprecated Functionality

`dpd.log` is no longer created by default, but can be loaded using the
`frameworks/analyzer/deprecated-dpd-log.zeek` policy script.
- The ``protocols/http/detect-sqli.zeek`` script has been deprecated in favor of a
new ``protocols/http/detect-sql-injection.zeek`` script to switch from the victim
