Compatibility

• the new release is compatible with previous 2.x.x releases.
• attention: this release will validate incoming data. Per default 30 seconds timeout and a maximum per 1 MB for each incoming data line. This should be fine in any use-case but please check yourself.
• attention: this release has changed the name of third (3rd) initialize argument from max_connections to max_processings - this is already the long existing origin intent of that argument. See index 3. for more details.

‼️ Please update at least to Release 2.3.3
