Important Notice - New Certificates Required for gRPC Transport

In order to secure the transport of log messages going forward Loggregator will require Metron cert & key as well as the Loggregator CA cert. You won't be able to deploy the this and future versions of Loggregator if you don't have these configured. See our README with specifics for generating and setting up your certs.

Important Notice - Cipher Suite Restrictions

This version of Loggregator restricts ciphers to use only the following 4 ciphers. This is a breaking change for some operators and a configurable property for opting into more cipher suites was introduced in Loggregator 85

TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
