v21.5.6

release v21.5.6

- arm[v8] support added to release pipelines
- schema registry preliminary release added
- trasaction bugfixes landed
- rpk container start fixes for multiple nodes on rpk container
- support for `rpk` to have `-1` parameters as args for kafka api

- added HoneyBadger testing

v21.5.5

release v21.5.5

Bugfix release

- This release will have slighly higher boot time
  for heavy users of compacted topics since it will
  discard previous indices and rebuild them using int64
  logic instead of int32 logic, that caused previously integer overflow
  causing an infinite loop for big partitions > 4GB files

- Fix stale readers in the cache

- Adds an advaned technique for fetching partition data
  that materializes topic metdata on a core-local basis for making
  a parallel plan of execution. We borrowed this technique from
  databases in the requqest-parse-plan-execute model for reading
  remote core streaming partitions. This has a 10-100x lower latency
  impact and improves throughput just a littlebit.

v21.5.4

release v21.5.4

Minor release

- add `rpk container start --set "..arbitrary flags"` which eliminates
the need for a configuration file

- fixes for transaction fencing

- added major compaction-controller rework to achieve steady state of
compaction without affecting foreground work in a constant learning
loop. Compaction automatically adjusts to the foreground work and
otherwise learns to keep up with the compacted segment work

This should eliminate connection timeouts on large CPU and IO hogs
for workloads with thousands of compacted partitions.

v21.5.3

release v21.5.3

- move to autogenerated fetch as the last hand written method. now all
  is codegen correctly
