opendht

• dht proxy: add topic/bundleId configuration for push notifications
• build/python: added support to build module with python3 -m build
• docker: updated images to use Ubuntu 22.04
• ci: update Docker images on release
• ci: build python package on release

• dhtrunner: removed ability to switch between the local and proxy dht nodes during runtime with a single dhtrunner. This feature was unused, broken, and was adding overhead. To switch between proxy and local client (or run both at the same time), create new dhtrunner instances.
• dhtrunner: don't bind UDP ports when acting as a proxy client.
• dhtrunner: fixed a bug that could cause the node state to be overridden when using the state_path configuration field.
• python/tools: updated virtual network builder ( @svinota )

• Fix build without jsoncpp

• value: make signature check and decryption independent from SecureDht
• c: add void to fix declaration of dht_version()

• dht: add config max_store_keys
• nodeinfo: add storage statistics
• c: add dht_version()
• tools/dhtcnode: various improvements
• tests: fix spurious failures in dhtunnertester

Fix typo in 2.4.1 release commit

• dht: increase default max values per key to 64k from 1024
• dht: better handle discarding values when the storage limit is reached, fixed potential use-after-free in storageChanged.
• c: allow to build from Autotools
• c: allow to enable logging to stdout/stderr
• build/cmake: respect OPENDHT_STATIC/OPENDHT_SHARED when building C bindings
• build/cmake: support RISC-V architecture by properly detecting atomic support
• build: updated Dockerfiles and CI pipelines
• build: added VSCode actions, tasks and dev container
• Hash: allow building from std::string_view
• Value: allow building from std::string_view
• misc: using various C++17 features, minor performance improvements
• tests: fixed some unit tests
• tools/dhtnode: show value count for listen and get operations
• tools/dhtcnode: updated to act similarly to dhtnode

• OpenDHT now requires C++17
• build/cmake: removed OPENDHT_LTO, use CMAKE_INTERPROCEDURAL_OPTIMIZATION instead
• infohash: allow building from std::string_view
• value: allow building queries from std::string_view
• c: dht_runner_run returns a standard error code in case of failure
• c: new bindings dht_runner_is_running, dht_runner_get_bound_port, dht_privatekey_decrypt
• c: dht_runner_ping can be provided a callback argument
• ci: updated Dockerfiles
• ci: removed travis

• dhtrunner: handle exceptions in run() to leave the node in a valid state after an initialization error.
• c: specify void argument for dht_runner_new

• dht: refactor broken exponential backoff logic during bootstrapping
• dht: performance/memory usage improvements
• c binding: add functions dht_value_new_from_string, dht_value_set_user_type to build value from string, or set the user-type field.
• c binding: install header with cmake
• build/cmake: minimum cmake version is now 3.10
• build/cmake: not using FindMsgpack anymore, relying on platform-provided cmake msgpack build information.

• crypto: cache certificate ID to improve performance
• crypto: allow to update certificate validity period
• various cleanup

• removed deprecated HTTP_PARSER_FORK build flag
• removed embedded argon2

• dhtrunner: a new stop argument to shutdown to fail every ongoing operation and shutdown immediately instead of waiting for completion.
• dhtrunner: new bind4, bind6 fields in DhtRunner::Config allow to provide address to bind
• dhtrunner: added async version of getPublicAddress
• dhtrunner: use default bound address if not set
• securedht: add IdentityAnnouncedCb to detect when identity is announced
• crypto: avoid generating 0 or negative certificate serial numbers
• cmake: fix building with peer discovery and without http
• various small fixes and performance improvements

since 2.1.1:

• dht: improve logic for value updates during a listen session
• dht: fix protocol error message when using non-default network id
• dht: fix issue with token renewal when next request is listen
• proxy: various fixes
• proxy server: allow to persist state to disk on shutdown
• crypto: added OCSP support
• updated Docker images

• dht: added packet replay for listen updates
• dht: added statistics to NodeStats
• dht: minor performance improvements
• moved bootstraping logic from DhtRunner to Dht (removes unecessary thread)

OpenDHT 2.0 includes many new and updated APIs as well as many performance and stability improvements.
