Release History - open AEA

2.2.9 (2026-06-23)

Plugins:

• open-aea-ledger-ethereum (EthereumApi.build_transaction): populates tx_params["from"] from tx_args["sender_address"] alongside the existing nonce read, and passes the address through self.api.to_checksum_address(...) once so the same EIP-55 form is used for both the nonce lookup and the built tx dict (matching the handling in get_transfer_transaction / get_deploy_transaction). The previous implementation built tx_params with nonce, value, and gas-pricing fields but no from, so web3's contract.functions.<m>().build_transaction(tx_params) produced a transaction dict without a from field, and the subsequent update_with_gas_estimate call sent that dict to eth_estimateGas. The JSON-RPC node defaulted missing from to the zero address, so contract methods whose state checks reject msg.sender == 0x0 (notably ERC20 approve on tokens guarded by require(owner != address(0), ...), e.g. Circle USDC) reverted during the estimate. build_transaction then returned None via the wrapping try_decorator, leaving callers without a usable transaction. #925

2.2.8 (2026-06-08)

Plugins:

• open-aea-ledger-ethereum (try_get_gas_pricing): eliminates a thread-safety race that caused tx["gasPrice"] to be set to a dict (e.g. {"maxFeePerGas": ..., "maxPriorityFeePerGas": ...}) instead of an integer. The previous implementation temporarily mutated w3.eth._gas_price_strategy via set_gas_price_strategy / generate_gas_price() / restore. A concurrent build_transaction call would invoke fill_transaction_defaults inside that window, observe a non-None generate_gas_price() result, force is_dynamic_fee_transaction = False, and store the entire strategy-returned dict as tx["gasPrice"]. Downstream arithmetic on that dict crashed with TypeError: unsupported operand type(s) for *: 'dict' and 'float', surfacing as an HTTP 500 in Pearl's backend. Fix calls the strategy callable directly — gas_price_strategy_callable(self._api, None) — which is what generate_gas_price() did internally but never touches w3.eth._gas_price_strategy. The race window is eliminated. #921

2.2.7 (2026-05-27)

Framework:

• aea.configurations.loader: exposes parse_service_yaml(file_pointer) -> (head, overrides) as a public module-level helper that parses a service YAML stream into the head document and the trailing override documents without schema validation. ConfigLoader._load_service_config now delegates to it. Lets downstream packagers (e.g. open-autonomy, which needs to substitute environment variables in the head document before validating it through its own Service config class) drop a hand-maintained copy of the parse-and-split logic. Raises ValueError("Service configuration file was empty.") whenever the head document is not a mapping — covers empty streams, bare ---, and YAML scalars (false, 0, "", []) — so the failure surfaces at parse time rather than as an opaque AttributeError from the downstream validator. #918

• aea.cli.scaffold.scaffold_item: saves ctx.cwd on entry and restores it via try ... finally. Previously the --to-local-registry branch swapped ctx.cwd to <registry_path>/<author> to make the inner fingerprint_item call resolve correctly, but never restored it, leaking the registry path back to callers. The post-fingerprint steps in the same function (notably the --with-symlinks block, which builds vendor symlinks from ctx.cwd) also see the original value again. Downstream wrappers that had to bracket scaffold_item with their own preserve_cwd = ctx.cwd; ...; ctx.cwd = preserve_cwd can drop the workaround. #918

• aea.contracts.base.Contract.from_config and aea.connections.base.Connection.from_config: pass the canonical packages-prefixed dotted path (packages.<author>.contracts.<name>.contract / packages.<author>.connections.<name>.connection) to load_module instead of the bare "contracts" / "connection_module" constants. With the new sys.modules registration in load_module (below), the bare keys would have collided across contracts and across connections loaded in the same process. Caller-visible behaviour is unchanged because load_module always returns a fresh module object. #918

• aea.skills.base._SkillComponentLoader: makes the dotted module path returned by _compute_module_dotted_path the canonical one (packages.<author>.skills.<name>.<file>), drops the now-redundant "exclude classes whose __module__ starts with this skill's dotted path" condition from _filter_classes, and updates the unused-class warning filter at _print_warning_message_for_unused_classes to keep classes that belong to this skill (both submodule classes and those defined at the skill's own __init__.py level) instead of dropping every packages.-prefixed class. Cross-skill re-exports (the canonical FSM composition idiom — class_name: AbciDialogues in skill.yaml bound to an AbciDialogues imported from a parent skill) still pass the filter because their __module__ starts with another skill's prefix, not aea.. The legacy _parse_module filter (used by Behaviour.parse_module / Handler.parse_module / Model.parse_module) drops the same local-prefix exclusion clause and switches its load_module call to the canonical packages-prefixed dotted path so its sys.modules cache entries do not collide on bare keys ("behaviours" / "handlers" / "models") across skills loaded in the same process. The remaining difference vs. _filter_classes is the legacy filter's name-allowlist gate (x[0] in component_names), which is unchanged. aea.helpers.base.load_module now registers the loaded module in sys.modules under its dotted path before exec_module (reusing any module already registered at that path so a subsequent ordinary from packages.<author>.skills.<name>.<file> import X returns the same object instead of re-executing the file and producing a second copy of every class defined in it), and rolls the entry back if exec_module raises. Together these eliminate the dual short-name / long-name class objects that downstream code (open-autonomy's _MetaPayload.registry) previously had to paper over with a key-rewrite loop. _compute_module_dotted_path is no longer a @classmethod (it reads self.skill_dotted_path) — internal API, no out-of-tree caller. #918

• aea.cli / aea.helpers.protocols: removes the two module-top logging.basicConfig(...) calls that fired as a side effect of import aea.cli and attached a stderr StreamHandler to the root logger. That orphan root handler survived the agent's logging.config.dictConfig (the config block has no root: key) and caught every aea.agent.* record a second time via propagation, producing the ] [INFO] vs ][INFO] doubling seen in operator captures. Fix moves the basicConfig in aea/cli/generate_all_protocols.py into the click command body and switches aea/helpers/protocols.py from setup_logger(__name__) to logging.getLogger(__name__). Behaviour change for operators: third-party library INFO/DEBUG logs (e.g. from web3, requests in the ledger plugins) that the orphan handler previously surfaced now go silent under an agent config without a root: block in logging_config. WARNING and above still appear on stderr via Python's logging.lastResort handler, though with that handler's bare-message format (just %(message)s, no level or logger-name prefix and no timestamp) rather than the formatted one the orphan installed. Operators who want the previous behaviour (timestamped third-party INFO/DEBUG) can add a root: block to logging_config in the agent's aea-config.yaml. #914 #917

• aea.helpers.env_vars.generate_env_vars_recursively: adds an is_strict_dict-style branch that JSON-encodes a whole dict as a single env var when any key fails the bash identifier rule (^[A-Za-z_][A-Za-z0-9_]*$), mirroring the existing is_strict_list handling. Previously a dict keyed by bash-unsafe strings (e.g. probability thresholds like "0.0", "0.6", "1.0") flattened per key to env var names such as ..._BET_AMOUNT_PER_THRESHOLD_0.0 that bash rejects at export time, so the override silently never reached the agent (see open-autonomy#2243). Also fixes a latent key-corruption bug where the per-key path round-tripped numeric-looking string keys through json.loads inside parse_list. All-safe-key dicts still flatten per key (no regression); mixed-key dicts now travel as one JSON-encoded env var. Agent-side reads through convert_value_str_to_type JSON-decode the :dict:/:list: placeholders unchanged. #915

Plugins:

• open-aea-ci-helpers (aea-ci check-dependencies): PyProjectToml.load now reads [tool.poetry.group.*.dependencies] tables in addition to the main [tool.poetry.dependencies] block, and accepts dict-form entries without an extras key (so {version = "...", optional = true} deps are no longer silently dropped). Implementation refactored around two helpers (_normalize_version, _dependency_from_spec) that handle string and dict forms uniformly; main-deps entries still win on name collisions. New unit tests at plugins/aea-ci-helpers/tests/test_check_dependencies.py cover the four entry formats, dev + docs groups, main-vs-group precedence, missing [tool.poetry] table, and the python ignore filter. Removes a sharp edge for anyone using aea-ci check-dependencies locally against a project with grouped or optional-without-extras deps. #916

Documentation:

• docs/connection-resilience.md rewrite addressing @DavidMinarsch's review of the original v2.2.6 doc. Adds a "What the protocol's speech acts imply" section that walks through the protocols in the repo and groups them by failure-channel shape (typed-error, status-with-classification, response-only, routing-failure) — making explicit how a protocol's speech_acts and reply rules pin down what the skill can decide. Terminology aligned with the framework convention (speech_acts over "vocabulary", with FIPA's "performatives" as a one-line synonym). Cross-links added to Design principles, Architectural diagram, Skills, Connections, Protocols, Message routing, Decision maker, and Ledger & Crypto APIs. Accuracy pass on the original draft (fetchai/default routing failures are surfaced by the fetchai/error skill, not the multiplexer; protocols decide failure-signal richness, not which layer retries; ACN reply rules clarified per performative). Net 261 → 91 lines for the same coverage plus the new protocol section. #912

2.2.6 (2026-05-14)

Framework:

• aea.helpers.base.try_decorator: enriches the swallowed-exception log line with the wrapped function's qualified name and the exception type. The previous log(error_message.format(e)) rendered a KeyError("maxFee") as just "...'maxFee'"; the line now reads "... [function=<qualname>, exc_type=KeyError]" so swallowed failures are diagnosable without changing the catch semantics. The public docstring also documents the raise_on_try=True escape hatch. #891 #910

Packages:

• valory/ledger connection: caps the per-attempt retry sleep in get_transaction_receipt / get_transaction at MAX_RETRY_DELAY = 60.0. Without the cap, the linear backoff retry_timeout * attempts grew unboundedly across the retry budget; capping bounds the worst-case loop while preserving the retry count. #891 #910
• valory/ledger connection: owns a dedicated ThreadPoolExecutor sized by a new max_thread_workers config (default 32) and shuts it down with cancel_futures=True on disconnect. Previously the dispatchers passed executor=None and shared Python's default asyncio thread pool with every other agent component; under sustained RPC outage RotatingHTTPProvider.make_request's sync sleeps accumulated abandoned threads in the shared pool. The dedicated executor isolates ledger work and surfaces the resource cost as operator-tunable config. #891 #910
• valory/ledger connection: lowers the shipped retry_attempts default in connection.yaml from 240 to 60 (and the in-code MAX_ATTEMPTS / RequestDispatcher.retry_attempts defaults from 120 to 60 to match). Now that RotatingHTTPProvider handles transport-layer rotation per call, the dispatcher budget is a layered backstop rather than the primary retry mechanism; the tighter default drops worst-case per-slot pool occupancy from ~230 minutes to ~50 minutes. Operators wanting the old budget can override in their connection config. #891 #910
• valory/ledger connection: improves the dispatcher's retry-loop warning log to include the exception type — self.logger.warning(e) previously rendered a KeyError("maxFee") as just "maxFee". Now uses "%s: %s", type(e).__name__, e for both the receipt and transaction loops. #891 #910
• valory/ledger connection: typed max_thread_workers as int at the assignment site so a stringified YAML value cannot slip past mypy and explode at ThreadPoolExecutor(max_workers=...). #891 #910

Plugins:

• open-aea-ledger-ethereum: tightens max_gas_fast per chain in CHAIN_EIP1559_OVERRIDES. Until now low-fee chains (Gnosis, Optimism, Base, Mode, Fraxtal, Arbitrum One) inherited the chain-agnostic 1500 gwei default, so a fee-oracle anomaly could authorise a tx priced 100×+ above the chain's normal range before the cap engaged. A production market-creator deployment on Gnosis submitted a routine multisend at 694 gwei (~700× the validator floor of 1 gwei) on 2026-04-22 (tx 0x727262d9…), paying 0.637 xDAI — ~45% of the agent's 30-day spend — while the inherited 1500 gwei ceiling did not trigger the fallback. New per-chain ceilings: Gnosis 30 gwei, Optimism / Base 100 gwei, Mode / Fraxtal 50 gwei, Arbitrum One 5 gwei. Sized to preserve operability during legitimate congestion (Base's March 2024 Dencun memecoin frenzy sustained ~24 gwei averages with bursts >100 gwei in individual blocks; Gnosis Tornado-deposit waves briefly hit 5–8 gwei) while bounding fee-oracle anomalies. Polygon (10000 gwei ceiling) and Celo (default 1500 gwei) are unchanged. valory/ledger connection.yaml mirrors the plugin-level ceilings. #909 #911
• open-aea-ledger-ethereum: gas-price strategies (Polygon EIP1559 and Eth Gas Station) broaden the except clause to cover (requests.exceptions.RequestException, ValueError, KeyError, TypeError) so malformed-response failure modes hit the documented fallback. response.json() raises JSONDecodeError (a ValueError subclass) on non-JSON 200; [speed] / ["maxFee"] subscripts raise KeyError on schema drift; a non-dict 200 body (a JSON null, array, or string from a CDN serving an error page) raises TypeError on the raw subscript. The previous except requests.exceptions.RequestException only caught network-shaped errors, so the documented fallback was bypassed for everything else. Both strategies now also emit a WARNING carrying the exception type so transport failures and schema drift are distinguishable in operator logs. #891 #910
• open-aea-ledger-ethereum: RotatingHTTPProvider docstring documents the interaction with the ledger connection's dedicated ThreadPoolExecutor — make_request is synchronous and uses time.sleep between retries, so worker threads in the connection's pool can be held for the duration of a retry sequence. Operators expecting high ledger concurrency under RPC degradation should size max_thread_workers to exceed peak concurrent retries for their RPC topology. #891 #910
• open-aea-cli-ipfs: routes the success-path json.loads calls in _api_post, add, and add_bytes through a single _safe_json_loads helper that raises a typed StatusError (with a printable, length-capped body preview) on non-JSON 200 responses. Previously a 200 carrying a non-JSON body (CDN HTML error page, truncated payload, gzipped body) raised an unhandled ValueError to the caller. The body preview replaces non-printable bytes with . and truncates at 80 chars so an arbitrary remote response cannot inject terminal-control sequences into operator logs. #891 #910

Documentation:

• New docs/connection-resilience.md framework-developer guidance for choosing retry and timeout behaviour. Covers where work happens in an agent (skills / connections / protocols), the distinction between within-agent and agent-to-external failures, per-component overview (HTTP client, HTTP server, ledger read-side / write-side / thread pool, RotatingHTTPProvider, IPFS, P2P libp2p variants, cosmos / fetchai / solana plugins), and a "picking a policy for a new component" checklist. Indexed in mkdocs.yml under Development – Advanced → Topic Guides. #891 #910

2.2.5 (2026-05-08)

Plugins:

• open-aea-ledger-ethereum: refactors RPCRotationMiddleware into a RotatingHTTPProvider (an HTTPProvider subclass) and constructs Web3(RotatingHTTPProvider(...)) directly in EthereumApi.__init__. Rotation now lives at the transport layer, so the standard web3 middleware chain — defaults plus any user-injected middleware — runs untouched on every call. Fixes the v2.2.4 regression where ledger_api.api.eth.<method>(...) returned plain dicts instead of AttributeDict, breaking attribute access (e.g. receipt.blockNumber) for downstream consumers reaching into the underlying web3 handle directly (open-autonomy TxSettler.settle(), etc.). All inner middleware (AttributeDictMiddleware, ENSNameToAddressMiddleware, FormattingMiddleware, BufferedGasEstimateMiddleware, GasPriceStrategyMiddleware, and any user-injected inject(layer=0) middleware) — silently dead under the v2.2.4 bypass — now run normally. ExtraDataToPOAMiddleware reverts to its standard placement at inject(layer=0). #889
• open-aea-ledger-ethereum: RotatingHTTPProvider.endpoint_uri is overridden as a property that reflects the currently active RPC URL, so diagnostic tooling (metrics, logs, request IDs) reading w3.provider.endpoint_uri post-rotation observes the correct endpoint instead of the URL passed to super().__init__. #889
• open-aea-ledger-ethereum: RotatingHTTPProvider raises ValueError at construction if rpc_urls (after Chainlist enrichment) is empty, replacing the silent failure that previously surfaced as an opaque requests error on the first RPC call. #889
• open-aea-ledger-ethereum: _mark_rpc_backoff and _is_rpc_healthy now run under the rotation lock (switched to threading.RLock so they remain callable from inside _rotate), closing a torn-read window on _backoff_until under concurrent error/rotation events. Unknown-category errors emit a WARNING log before re-raising so novel transport failures are no longer silent. classify_error now returns a Literal[...] so the categorical switches in make_request / _handle_error_and_rotate are mypy-checkable. #889

Tooling:

• strategy.ini: loosens the urllib3 license-whitelist pin from ==2.6.3 to >=2.6.3,<3 to track minor upgrades that requests resolves transitively. Resolves the liccheck CI failure where requests pulled urllib3 2.7.0 while the strategy still authorized only 2.6.3. #889

2.2.4 (2026-05-07)

Plugins:

• open-aea-ledger-ethereum: makes RPCRotationMiddleware's connection-reset detection locale-safe. classify_error now matches on isinstance(ConnectionResetError), isinstance(ssl.SSLError) (excluding ssl.SSLCertVerificationError), and errno == 10054 (WSAECONNRESET) — and walks the __cause__/__context__ chain — instead of substring-matching the localized OS message. On non-English Windows installs, transient resets that previously slipped through as "unknown" and skipped the retry path are now retried correctly. Resolves the terminate_and_withdraw HTTP 500 reported on Polystrat / Pearl. #887
• open-aea-ledger-ethereum: on connection-reset errors, RPCRotationMiddleware now evicts the cached requests.Session for the affected provider (_evict_provider_session) before retrying, so the next attempt performs a fresh TCP/TLS handshake instead of reusing the half-closed pooled socket. The cache read and clear() execute under the session manager's _lock when one is exposed; the _current_index snapshot in _handle_error_and_rotate is taken under the middleware's own lock. Eviction failures are logged at WARNING with exc_info=True so recovery-path regressions remain diagnosable. #887
• open-aea-ledger-ethereum: removes the len(rpc_urls) > 1 gate from RPCRotationMiddleware.wrap_make_request — single-URL deployments (Pearl's default) now enter the retry / session-eviction loop. The retry budget remains min(MAX_RETRIES, len(rpc_urls) * 2); when the configured MAX_RETRIES is clamped by the pool size, an INFO log line is emitted once at build() time. On genuine pool exhaustion a single WARNING summary is emitted before the final raise, distinguishing systemic outages from one-off transient failures. #887
• open-aea-ledger-ethereum: changes the registration of ExtraDataToPOAMiddleware from inject(layer=0) (innermost) to add(...) (outermost). Required because RPCRotationMiddleware.wrap_make_request calls each provider directly and bypasses the inner middleware chain (formatters, ENS, retry, exception, AttributeDictMiddleware); PoA processing must therefore wrap the rotation layer to apply on every response. Fixes BSC extraData field truncation that surfaced during CI. #887
• open-aea-ledger-ethereum: widens AttributeDictTranslator.to_dict to accept plain dict (Union[AttributeDict, TxReceipt, TxData, Dict[str, Any]]). Required because responses returning through the rotation path arrive as plain dicts rather than AttributeDict instances (the inner middleware chain is bypassed). TxReceipt and TxData are TypedDicts and continue to flow through the same arm. The existing AttributeDict callers are unaffected. #887

Tests:

• Reworks ACNWithBootstrappedEntryNodesDockerImage (the libp2p ACN docker fixture) to support a multi-container topology (bootstrap node plus two entry nodes), replacing the single-container wait() with a per-container port poll. Resolves flaky ACN integration tests; unrelated to the WSAECONNRESET fix but absorbed into the same release for CI continuity. #887

2.2.3 (2026-05-04)

AEA:

• Bumps the GitPython floor to >=3.1.47,<4.0.0 to pull in the upstream fixes for GHSA-rpm5-65cw-6hj4 (insecure non-multi options in clone / clone_from) and GHSA-x2qx-6953-8485 (blind local-file-read via git ls-remote). #884

Tooling:

• Collapses the four out-of-band lint/test config files (pytest.ini, setup.cfg, .pylintrc, .gitleaks.toml) into pyproject.toml + tox.ini (Wave 2a). Pytest config moves to [tool.pytest.ini_options]; the only remaining setup.cfg content is a minimal [isort] block consumed by aea generate-all-protocols to format generated protocol code. [mypy] and per-module [mypy-*] overrides plus the [darglint] block live at the bottom of tox.ini (mypy/darglint don't read pyproject.toml); the [testenv:mypy] command passes --config-file=tox.ini so they're picked up. #885
• Bumps tomte to ==0.7.0 (released). Every lint testenv now references {envsitepackagesdir}/tomte/configs/<config> for its config — pylint, mypy, isort, flake8, bandit, darglint, safety, gitleaks — instead of carrying a forked copy in this repo. The pylint testenv keeps OAEA-specific extras (--ignored-modules=…, --ignore-patterns=…) inline because they're project-specific. #885
• Slims pyproject.toml to strict PEP 621 + [tool.poetry] + [tool.pytest.ini_options] + [tool.isort] (no [tool.pylint.*] / [tool.flake8] / [tool.mypy] blocks). #885
• Updates the gitleaks GitHub Actions job to install tomte and run with --config={envsitepackagesdir}/tomte/configs/gitleaks.toml. The previous job ran against gitleaks default rules. .gitleaksignore regenerated via tomte freeze-gitleaks (66 historical fingerprints). #885

2.2.2 (2026-04-24)

Plugins:

• open-aea-ledger-ethereum: generalises EthereumApi.get_l1_data_fee to dispatch by chain_id. Covers OP-stack (Optimism, Base, Mode, Fraxtal) via the GasPriceOracle and Arbitrum Nitro (Arbitrum One, Arbitrum Nova) via the NodeInterface precompile; returns 0 on any other chain. Non-OP-stack L2 queries previously failed silently. Callers that need the L1 data fee (e.g. drain-address budgeting) invoke the helper explicitly — it is safe to call on any chain. #780
• open-aea-ledger-ethereum: adds chain-aware fallback defaults inside the plugin itself via a unified CHAIN_EIP1559_OVERRIDES map applied by get_default_gas_strategy(chain_id). Per-chain tunings: Optimism / Base / Mode / Fraxtal (5 gwei maxFeePerGas, 3 gwei tip — OP-stack), Arbitrum One (2 gwei maxFeePerGas, 1 gwei tip — above the 0.1 gwei floor), Polygon (6000 gwei maxFeePerGas, 30 gwei tip, min_allowed_tip 30 gwei — clears the validator-enforced priority fee floor; max_gas_fast 10000), Celo (50 gwei maxFeePerGas, 25 gwei tip, min_allowed_tip 25 gwei — above the 25 gwei network floor), and Gnosis (5 gwei maxFeePerGas, 1 gwei tip, min_allowed_tip 1 gwei). All other chains inherit DEFAULT_FALLBACK_ESTIMATE. Applies whether the ledger is built via make_ledger_api('ethereum', chain_id=...) directly OR through the valory/ledger connection, and covers both eip1559 and eip1559_polygon strategies. User-supplied gas_price_strategies kwargs still take precedence. #775
• open-aea-ledger-ethereum: improves the fallback-gas warning emitted by get_gas_price_strategy_eip1559 to name the actual maxFeePerGas / maxPriorityFeePerGas values being used and point at the gas_price_strategies kwarg as the supported override. #775
• open-aea-ledger-ethereum: updates POLYGON_GAS_ENDPOINT from the deprecated gasstation-mainnet.matic.network/v2 to the canonical gasstation.polygon.technology/v2 per Polygon docs. Affects callers of the eip1559_polygon strategy. #775
• open-aea-ledger-solana: bumps solana>=0.33.0,<0.34.0, solders>=0.21.0,<0.22.0, anchorpy>=0.20.0,<0.21.0. Removes the transitive cachetools<5 pin that solana-py 0.29–0.32 carried, unblocking consumers that need cachetools>=7 (e.g. tomte[tox]==0.6.5 → tox 4.46). solana.blockhash.BlockhashCache was removed upstream in 0.33.0; inlined locally as a minimal TTL cache to preserve the plugin's public import surface. See open-autonomy#2479. #880
• open-aea-ledger-ethereum-hwi: drops the orphaned construct<=2.10.61 cap from the plugin's install_requires and the repo-level pyproject.toml / tox.ini, unblocking dependency resolution for consumers that pull in the solana plugin alongside hwi. #882

Packages:

• valory/ledger connection: aligns per-chain fallback_estimate and min_allowed_tip in connection.yaml with the new plugin-level defaults — Optimism / Base / Mode / Fraxtal 5 gwei, Arbitrum 2 gwei, Polygon 6000 gwei + 30 gwei tip + max_gas_fast 10000, Celo 50 gwei + 25 gwei tip, Gnosis 5 gwei + 1 gwei tip. Also adds a Polygon-specific eip1559_polygon block (the chain's default strategy) so tuned values apply on the default path, not only when callers explicitly select eip1559. Technically redundant now that the plugin ships matching defaults, but keeps the YAML self-documenting and defensible if the plugin defaults ever drift. #775

2.2.1 (2026-04-15)

AEA:

• Populates the PyPI Description section for the root package and every plugin from the corresponding README.md (was empty / a one-liner before). #876

Plugins:

• Removes the unmaintained open-aea-ledger-ethereum-flashbots plugin and every CI / docs / config reference to it. Consumers should drop ethereum_flashbots from the valory/ledger connection config and remove aea_ledger_ethereum_flashbots PyInstaller flags. See docs/upgrading.md.
• Makes aea-ci generate-api-docs configurable (--source-dir, --packages-dir, --plugins-dir, --docs-dir, --default-package, --ignore-plugin, --ignore-prefix, --parallel) so downstream repos can reuse it. Parallel mode now surfaces worker exceptions instead of silently dropping them. #876
• Adds aea-ci check-third-party-hashes — verifies local packages/packages.json third_party entries against one or more upstream repos, with per-upstream fault tolerance. #876

Tests:

• Re-enables the "Local" test_libp2p DHT integration tests against the rebuilt valory/open-acn:latest image (libp2p v0.33.2). Switches fixture entry-peer multiaddrs from 0.0.0.0 to 127.0.0.1 to satisfy libp2p v0.33's stricter dial checks. #876

CI:

• Adds bugs.python.org/issue8296 to the doc-link skip list to eliminate a flaky external URL. #876

2.2.0 (2026-04-13)

AEA:

• Removes requests, ipfshttpclient, jsonschema, python-dotenv, semver, morphys, ecdsa, base58/multibase/multicodec/pymultihash from core dependencies -- replaced with stdlib or inlined implementations. #858 #859 #860 #861 #862 #863 #866 #867
• Adds env var resolution on component override sections in AEABuilder. #868
• Switches to strict PEP 440 version parsing (replaces semver). #859
• Enhances env file parser to support export prefix, ${VAR} interpolation, and inline comments. #860
• Inlines IPFS HTTP client (replaces ipfshttpclient). #866
• Inlines JSON Schema Draft-04 validator (replaces jsonschema). #862
• Inlines secp256k1 validation (replaces ecdsa from base deps). #863
• Inlines multiformat helpers (replaces base58/multibase/multicodec/pymultihash). #861

Plugins:

• Adds new plugin: open-aea-dev-helpers (aea-dev) with 7 release/dev tool commands migrated from scripts/. #865
• Migrates check_copyright, check_doc_links, freeze_dependencies to tomte CLI. #865
• Widens dependency pins across all plugins for broader compatibility. #864

Go / libp2p:

• Bumps Go module dependencies to Go 1.24. #872
• Restores circuit-relay v2 routing parity. #872
• Fixes golangci-lint integration for libp2p_node. #872
• Adds Python<->Go FIPA e2e test harness to CI. #872

Tooling:

• Migrates from Pipenv to Poetry. #857
• Bumps tomte from 0.6.1 to 0.6.5. #857
• Deletes 12 Python scripts from scripts/ (migrated to plugins). #865 #871
• Removes benchmark/checks/ legacy scripts. #865
• Comprehensive docs refresh. #872

CI:
