- support for signing requests ( by setting the "key" - property in config)
- fix possible memory leaks
- optimize configuration
- add valgrind and QEMU to the CI 
- allow non stats requests
- add user-agent with version to requests
- added examples to the doc (java, python, wasm)
- activate nodelist filtering
- added verified hashes cache to improve performance
- added Generics to wasm with suupport for custom converters
- Update lastNodeList only after response is verified

v2.2.2: Bugfixes

- recursion bug fixed during nodelist update
- added internal util rpc-methods to handle signatures and key handling ( https://in3.readthedocs.io/en/develop/api-c.html#rpc )
- fixed memory issue during whitelist update
- added support for bool in tohex function of in3 wasm

v2.2.1: update ENS-Registry

- fix ENS-Registry address
- fix arguments to support requestCount and maxAttempts
- increase the default maxAttempts to 5

v2.2.0: ENS-Support

ENS-Support

more changes:

• ENS-Support ( explicitly with in3_ens or indirectly in the comandline-tool)

  > in3 call -to cryptokitties.eth "pregnantKitties():uint" 
  1221

• add Autocompletion for zsh

  curl https://raw.githubusercontent.com/slockit/in3-c/develop/scripts/_in3.sh > /usr/local/share/zsh/site-functions/_in3.sh
  

• add NodeList-inspection in the comandline

  in3 in3_weights

• better error-reporting during configuring the client
• allow manual preselected data- and signers in the request ( data_nodes and signers in the in3-object of the rpc-request )
• added cache for already signed hashes ( we don't ask for signatures for a blockhash we have already verified before)
• optimize nodelist-updates (get updates and proof from claiming node)
• optimize signer-seclection node picking method
• added static code analyser (cppcheck) to CI
• optimized response-time based reputation
• fixed filter eth_getFilterChanges correcting the fromBlock
• fixed memory-leak with binary transport
• fix Loader-Issues with Android-ARM-build

v2.1.0: first stable release

- minor bugfixes
- clear Cache
- code coverage increased

v2.0.26-RC3: whitelist support

- support for local whitelist (`whiteList`-property in the nodes-config used when configuring)
   ```js
  {"nodes":{
    "0x1":{
      "whiteList":["0x123455","0x1234556"]
    }
  }}
   ```
- support for contract-based whitelist (`whiteListContract`-property in the nodes-config used when configuring)
   ```js
  {"nodes":{
    "0x1":{
      "whiteListContract":"0x123455"
    }
  }}
   ```
- support for single_chain-instances (`in3_for_chain()`)
- cmake-option to reduce size of the binary for about 37kB, but slower ec-operations.  (`-DUSE_PRECOMPUTED_EC=true`)

v2.0.25-RC3: cleanup

- refactore public api to be consistent with underscroe_case
- optimized init ( `in3_from_chain` - old `in3_new` is now deprecated)
- fixed signer selection (https://git.slock.it/in3/c/in3-core/issues/132)

v2.0.24-RC3

- fixed hash collision in eth_getLogs proof

v2.0.23-RC3: evm verification

- EVM Errorcodes optimization
- WASM-Test cache handling cleanup
