2020-02-06, Version 10.19.0 'Dubnium' (LTS)

This is a security release.

Vulnerabilities fixed:
* **CVE-2019-15606**:
          HTTP header values do not have trailing OWS trimmed.
* **CVE-2019-15605**:
          HTTP request smuggling using malformed Transfer-Encoding header.
* **CVE-2019-15604**:
          Remotely trigger an assertion on a TLS server with a malformed
          certificate string.

Also, HTTP parsing is more strict to be more secure. Since this may
cause problems in interoperability with some non-conformant HTTP
implementations, it is possible to disable the strict checks with the
`--insecure-http-parser` command line flag, or the `insecureHTTPParser`
http option. Using the insecure HTTP parser should be avoided.
