Fix the inverted insecure_skip_verify TLS option

PR #5134 · closes #1467

The Prometheus remote-write exporter passed tls_config's insecure_skip_verify straight through as the verify argument to requests.post, which inverted it: True kept certificate checks on, and False — the value that reads as the safe choice — silently turned them off, leaving metric exports open to interception by anything on the network path. The fix is one word, negating the value so the option means what the Prometheus remote_write setting it is named after means. It shipped with a regression test parametrized over both values that fails before the change and passes after, plus a manual check against a self-signed HTTPS server.

Return 413 when the multipart form part limit is exceeded

PR #4990 · closes #4439

A multipart upload that exceeded the configured part limit was rejected with 400 Bad Request. 400 tells a client its request was malformed, so a client that had sent a perfectly well-formed upload — just a large one — could not tell the two cases apart, and no retry or chunking strategy could be written against it. Limit violations now return 413 Request Entity Too Large while genuinely malformed bodies keep 400, and files already written to disk are still cleaned up on the error path. Shipped with regression tests, a changelog entry and a breaking-change note.

Correct the dataclass_transform ordering metadata

PR #4591

Strawberry's decorators declared order_default=True in their PEP 681 dataclass_transform metadata, which promises a type checker that ordering methods will be generated. At runtime Strawberry wraps dataclasses with ordering disabled. Static and runtime behaviour disagreed, and the cost landed on users: mypy rejected valid hand-written __lt__ and __gt__ implementations on Strawberry types. Corrected to order_default=False across the core, federation and schema-directive decorators, with regression coverage on each.

Make the resolver documentation examples self-contained

PR #4581

Two resolver examples depended on a type defined earlier on the page, so copying either one into a file raised NameError — the first thing a new user does with a documentation snippet is run it. Both examples now carry their own import and type definition and execute standalone.

Warn on deprecated and unknown dataset config fields

PR #758

The dataset config parser accepted arbitrary keys. A mistyped incremental_round was stored and ignored while incremental_rounds quietly kept its default and passed validation, so the run failed much later with an error naming three keys the user had never written and saying nothing about the one they had. Adds warnings for deprecated train_url / test_url inputs and for unrecognised keys, moving the diagnostic to parse time. Backward compatible — valid configurations are unaffected.

Correct the filename in the Data Info File error message

PR #756

The loader raised an error instructing the user to name their file data_info.json, while the format check only recognised metadata.json. Following the error message reproduced the same error exactly — an error message that costs more time than no error message. Renamed to the file the loader actually looks for.
