We have eliminated the old configuration proxy.config.remap.use_remap_processor, and instead it's all controlled via the proxy.config.remap.num_remap_threads configuration. The default for the number of remap threads is now 0, which means that the remap processor threads feature is disabled. To enable the remap processors, set this configuration to a value greater than 0.

The hash function for the HostDB cache has changed. This does not require any configuration changes, but the first time running the new version, you will see a log message like {{WARNING: header missing/corrupt: \[hostdb.config\] : reinitializing database}}. |

Default RAM cache size
The default RAM cache (if proxy.config.cache.ram_cache.size is set to "-1") has been increased by a magnitude. A 128GB disk will now allocate 1.2G of RAM cache, whereas previously it would only allocate 128MB.
