[DRBD-user] LINSTOR Operator v2.1.1 and v1.10.4

[Moritz Wanzenböck]

Dear LINBIT SDS on Kubernetes users,

We've recently released updates for our Kubernetes Operator.

First, there is version v2.1.1 for users of our next-generation Operator.
Along with the common image updates, we've improved the way DB migrations
for LINSTOR are handled. We also store the LINSTOR Satellite logs directly
on the host, providing improved traceability should something go wrong.

For users of Operator v1, there is now version v1.10.4. This also comes
with the usual image updates, as well as improved registration of Pods in
LINSTOR.

A reminder for users of Operator v1: We will maintain the existing Operator
v1 with bug fixes and new software versions until the end of 2023. We will
provide a dedicated upgrade path to Operator v2. We recommend all v1
installations to continue to use v1. For all new clusters we recommend
using v2.

To get specific instructions to apply the update, check our users guide: [1]

Source code is, as always, available upstream. [2]

Best regards,
Moritz
