- update to 1.8.0:
* Upgrade bundled zlib version from 1.2.8 to 1.2.11 in the `librdkafka.redist`
NuGet package. The updated zlib version fixes CVEs:
CVE-2016-9840, CVE-2016-9841, CVE-2016-9842, CVE-2016-9843
See https://github.com/edenhill/librdkafka/issues/2934 for more information.
* librdkafka now uses [vcpkg](https://vcpkg.io/) for up-to-date Windows
dependencies in the `librdkafka.redist` NuGet package:
OpenSSL 1.1.1l, zlib 1.2.11, zstd 1.5.0.
* The upstream dependency (OpenSSL, zstd, zlib) source archive checksums are
now verified when building with `./configure --install-deps`.
These builds are used by the librdkafka builds bundled with
confluent-kafka-go, confluent-kafka-python and confluent-kafka-dotnet.
* Producer `flush()` now overrides the `linger.ms` setting for the duration
of the `flush()` call, effectively triggering immediate transmission of
queued messages. (#3489)
* Lots of bugfixes, see included CHANGELOG.md for details
- build against system libraries rather than bundled ones
- enable all features
