[#3674] Fixed ChangeLog

[#3652] Remove the config history completely

- Removed revert() which makes no sense anymore.
- Since rollback() was significantly simplified, renamed it to
  clearStagingConfiguration().
- Removed kludgy ensureCurrentAllocated(). The only new required
  allocations are on constructor and on clear().

[#3652] add ChangeLog entry

[#3652] Fix memory increase on reconfiguration

Caused by config history. The config history was soft-disabled.
Code had to be refactored to enable CONFIG_LIST_SIZE == 0.
