5.0.1

Fixed

• Fix batch lookups with a fields selection: the API applies the filter to the whole batch
  response body, so each field is now prefixed with results. on batch endpoints. Previously
  the filter stripped the results array itself and the lookup crashed with an IndexError.
• Raise a descriptive ClientError when a batch response contains fewer results than requested
  items, instead of crashing with an IndexError.

5.0.0

Added

• Add an asyncio-based AsyncIpregistryClient with the same feature set, available with the async
  extra: pip install ipregistry[async].
• Add configurable retries through IpregistryConfig: retry_max_attempts, retry_interval,
  retry_on_server_error and retry_on_too_many_requests (honoring the Retry-After header).
  Transient network errors are now retried too.
• Add a typed ErrorCode enum exposed as ApiError.error_code.
• Add IpregistryLookupError as the primary name for per-entry batch lookup errors; the previous
  LookupError name, which shadows the Python builtin, remains available as an alias.
• Ship a py.typed marker so type checkers use the library's annotations.
• Add automatic splitting of batch lookups larger than the API limit of 1024 items into concurrent
  chunks, tunable with the max_batch_size and batch_concurrency client options.
• Add close() and context manager support to IpregistryClient, plus an optional session
  option to provide a custom requests.Session.
• Add a user_agent configuration option to customize the User-Agent header.
• Add a release workflow publishing to PyPI through trusted publishing, a ruff lint workflow, and
  a weekly scheduled workflow running tests against the live API.

Changed

• Require Python 3.10+.
• Migrate the project metadata to the standard PEP 621 format and switch project management
  from Poetry to uv.
• Update all dependencies to their latest versions and remove the dependency on tenacity.
• Reuse pooled HTTP connections through a requests.Session instead of opening a new connection
  per request.
• Align the default request timeout with other Ipregistry client libraries: 15 seconds instead of 5.
• Origin lookups are no longer cached: cached requester data would be stale or wrong when the
  network context changes.
• Cache keys are now deterministic regardless of the order lookup options are given in.
• Remove the redundant retry on origin_lookup_ip that could triple retry attempts.
• Detect the Yahoo Slurp crawler in UserAgents.is_bot.

Fixed

• Fix nested model fields (Connection, CurrencyFormat, UserAgent device/engine/os, RequesterIpInfo user_agent)
  raising a validation error when excluded from a response using the fields parameter.
• Fix str(ApiError) returning a tuple representation instead of the error message.
• Raise ClientError instead of leaking a JSONDecodeError when an error response has a non-JSON body.
• Raise ValueError instead of TypeError when lookup_ip is called with a non-string input.
• Support boolean and numeric option values when building request URLs and cache keys.
• Reject float inputs when detecting ASN values in lookup_asn.

4.0.0

Changed

• Require Python 3.8+.
• Add new functions for retrieving Autonomous System data: batch_lookup_asns, lookup_asn, origin_lookup_asn.
• Add new functions for user-agent header value parsing: batch_parse_user_agents, parse_user_agent.
• API key is passed as header value and no longer as query parameter.
• Client library method are now wrapped in a new ApiResponse object that includes a mean to retrieve metadata
  about credits and throttling in addition to data.
• Introduce data model for responses to enable field value access using dot notation and ensure code autocompletion functionality.
• Rename all function and variable names to adhere to snake_case convention.
• Replace the function named lookup by 3 new functions: batch_lookup_ips, lookup_ip and origin_lookup_ip.
• Rename IpregistryConfig option apiUrl to baseUrl.
• Rename UserAgent utility class to _UserAgents.

3.2.0

Changed

• Dependencies are now managed with Poetry.

Fixed

• Fix setup.py import assumes deps already installed (#37).

3.1.0

Changed

• Dependencies update

3.0.0

Changed

• Drop Python 2 support.
• Rename DefaultCache to InMemoryCache.

2.0.1

Fixed

• Fix packaging with version 2.0.0 deployed on pypi.

2.0.0

Changed

• Disable caching by default since people are often confused by this default setting. You can enable caching by following what is explained in the README.
• Increase maximum timeout to 15s from 3s.

1.1.0

Changed

• Decrease the default cache period to 10min from 24h.

  This is to better handle use cases that require fresh security data.
  Indeed, such data is updated multiple times each hour.

  You can still configure the cache period to a higher value:

1.0.0

First public release.
