Changes in version 0.8.10                        

  - replace Rf_error with Rcpp::stop in C++ code for proper stack
    unwinding and memory cleanup (#971). This change prevents memory
    leaks when errors occur in the populate function and ensures
    compatibility with future Rcpp versions. Thanks to @Enchufa2 for
    raising issue.

                 Changes in version 0.8.9 (2026-02-17)                  

  - fix populate function to normalize custom subclasses of any base
    type to match interface specification. Custom classes (e.g.,
    fs_path, glue, custom integer/numeric subclasses) are stripped to
    their base types, while R built-in temporal classes (POSIXct,
    POSIXt, Date) are preserved for proper serialization. When custom
    classes inherit from temporal classes, only the temporal portion is
    retained.

                 Changes in version 0.8.8 (2026-01-13)                  

  - fix C++ compilation issues on older R versions by refactoring code
    to use C++11 standard and requiring R >= 4.1.0 (#957). Thanks to
    @detule for raising the issue.
  - fix populate function to correctly infer and add type tags for
    nested structures, particularly for numeric values inside map
    attributes in DynamoDB operations (#959). Thanks to @dleopold for
    raising the issue.

                 Changes in version 0.8.7 (2025-11-25)                  

  - fix timezone handling in bearer token tests (#955). Thanks to
    @kyleam for raising issue.

                 Changes in version 0.8.6 (2025-11-19)                  

  - fix default json scalar from standard '"%s"' and use R classes to
    determine json parsing.
  - support httr2:::StreamingBody class
  - add support for bearer token authentication for AWS services (e.g.,
    Bedrock). Bearer tokens can be provided via environment variables
    AWS_BEARER_TOKEN (generic) or AWS_BEARER_TOKEN_<SERVICE>
    (service-specific, e.g., AWS_BEARER_TOKEN_BEDROCK). Optional
    expiration can be set via AWS_BEARER_TOKEN_EXPIRATION. When
    available, bearer authentication is automatically used instead of
    AWS Signature V4 for supported services, following RFC 6750
    Section 2.1 (#952). Thanks to @benhmin for raising issue.

                 Changes in version 0.8.5 (2025-07-25)                  

  - restrict httr2 version (#933). Thanks to @idavydov for raising the
    issue.
  - fix host prefix allowing for parameters to be passed in based on
    hostLabel (#941). Thanks to @dannypage for raising the issue.
  - add s3_virtual_address to force how url address is built (#937)
    thanks to @noamross for raising the issue.

                 Changes in version 0.8.4 (2025-05-27)                  

  - fix ensure byte buffer push back is working correctly in
    paws_stream_parser (#930). Thanks to @joeramirez for raising issue.

                 Changes in version 0.8.3 (2025-04-17)                  

  - fix query being incorrectly parsed (#923). Thanks to @joeramirez for
    raising issue.

                 Changes in version 0.8.2 (2025-03-05)                  

  - fix issue regex timeout or rstudio crashes in windows (#901, #905).
    Thanks to @anpatton for debugging issue.
  - revert auto sso retry, this was causing tokens being built
    incorrectly (#896) thanks to @sckott for testing

  - skip network connection unit tests on cran

                 Changes in version 0.8.0 (2025-02-07)                  

  - migrate backend from httr to httr2
  - enrich sso message (#844). Thanks to @hadley for raising issue.
  - attempt to automatically set/refresh sso credentials by calling aws
    cli (#844)
  - moved api log level to debug and trace. This is to prevent info
    level being saturated by api calls.
  - new PawsStreamHandler, allows paws to handle aws stream event
    (#842). Thankyou to @hadley for developing the initial solution in
    httr2.
  - deprecated custom handler for s3_unmarshal_select_object_content in
    favour or new streamhandler
  - migrate parse_url, parse_query_string and build_url to cpp for
    performance improvement.
  - ensure url is set to lower case before signature
  - migrate vendor from aws-sdk-js to aws-sdk-python boto3.

  - Fix operations that take empty arguments, e.g.
    s3$get_bucket_website.

                 Changes in version 0.3.16 (2022-02-19)                 

  - Fix single sign on (SSO) authentication on Windows.

                 Changes in version 0.3.15 (2021-12-04)                 

  - Provide the ability to use credentials obtained from AWS SSO login,
    i.e. aws sso login --profile my-profile.
  - Fix timestamps in the S3 API, e.g. LastModified from get_object.

                 Changes in version 0.3.14 (2021-10-24)                 

  - Skip tests for issue network request function to avoid CRAN check
    errors.

  - Support AWS_DEFAULT_REGION in addition to AWS_REGION.
  - Support calling SDK operations within do.call, including any
    user-supplied configuration to the service, e.g. a custom endpoint.

                 Changes in version 0.3.12 (2021-08-15)                 

  - Support S3 access points in all S3 operations that accept a bucket
    argument. Fixes #403.
  - Fix certain API requests for S3 that were malformed due to
    mistakenly including empty list elements, e.g.
    s3_put_bucket_lifecycle_configuration. Fixes #438.
  - Add an option to immediately close all HTTP connections, instead of
    the default behavior which will reuse connections for requests
    within 5 seconds. Using this feature allows you to switch
    credentials within 5 seconds without getting your request rejected
    with a SignatureDoesNotMatch error. Example usage: s3 <-
    paws::s3(config = list(close_connection = TRUE)). Fixes #431.

                 Changes in version 0.3.11 (2021-05-20)                 

  - Fix parsing of shared configuration and credential files.

                 Changes in version 0.3.10 (2021-05-15)                 

  - Use path style URLs for S3 when using custom endpoints, (e.g.
    localhost:9000/mybucket). This is useful when using software like
    MinIO. When not using custom endpoints, Paws will in general use
    "virtual hosted" URLs (e.g. mybucket.s3.amazonaws.com) except in
    special cases.

  - Use path style URLs for S3 when using the new s3_force_path_style
    option when calling paws::s3(), e.g.:
    
    s3 <- paws::s3(config = list(
        s3_force_path_style = TRUE
    ))

  - Add support and a default value for timeout, how long to wait in
    seconds for an acknowledgement of an HTTP request before failing.
    Default = 60. This is user configurable by adding arguments to the
    service call, e.g.
    
    svc <- paws::svc(config = list(timeout = 10))

  - Don't skip lower case field names for REST location elements. For
    example, lexmodelbuildingservice$create_bot_version(name, checksum)
    previously failed due incorrectly skipping the name field.

                 Changes in version 0.3.9 (2021-02-26)                  

  - Support multifactor authentication, using the mfa_serial shared
    configuration file item.
  - Support AWS_CONFIG_FILE, AWS_SHARED_CREDENTIALS_FILE,
    AWS_CREDENTIAL_EXPIRATION, and AWS_EC2_METADATA_DISABLED environment
    variables. See
    https://github.com/paws-r/paws/blob/main/docs/credentials.md for
    explanations of all settings.
  - Cache credentials in each service object.

                 Changes in version 0.3.8 (2021-01-25)                  

  - Use no timeout by default when making HTTP requests. The previous
    release set the default timeout to 10 seconds, which prevented users
    from downloading large files.

                 Changes in version 0.3.7 (2021-01-18)                  

  - s3$put_object will now read in files when given file paths for the
    Body parameter. Previously it would accept only blobs, e.g. from
    readBin.

                 Changes in version 0.3.6 (2020-12-05)                  

  - Add the error response and HTTP status code to the condition object,
    in addition to having it be in the condition object's attributes.
    This is in response to a request in issue #329.
  - Make errors be of class paws_error in addition to their other
    classes, e.g. http_400, error, condition.
  - Correctly unmarshal EC2 API error responses.

                 Changes in version 0.3.5 (2020-10-25)                  

  - Support getting AWS credentials from IAM roles using shared
    configuration file items role_arn, credential_source, and
    source_profile.
  - Support getting AWS credentials from running a process using shared
    configuration file item credential_process.
  - Fix decoding of errors from the EC2 API.
  - Fix support for newlines in arguments in S3 and other REST XML
    protocol APIs.

                 Changes in version 0.3.4 (2020-09-06)                  

  - Support S3 object keys with spaces.
  - Support writing empty S3 objects.
  - Support integers larger than 2^31 - 1 in API responses, e.g. S3
    object size, by using 64-bit numeric objects rather than 32-bit
    integer objects.

                 Changes in version 0.3.3 (2020-07-19)                  

  - Decode base64-encoded blobs to raw vectors. Previously, Paws decoded
    them to UTF-8 inappropriately, which would fail for any data other
    than text.
  - In some cases, httr/curl do not decompress the response body. In
    these cases, check whether it looks compressed and try decompressing
    it.

                 Changes in version 0.3.2 (2020-06-22)                  

  - Support the S3 operation SelectObjectContent in
    s3$select_object_content. This operation allows you to query a data
    file in S3 using SQL.
  - Correctly decode Unicode strings in API responses received from AWS,
    such as "Me voy a casa mañana.".

                 Changes in version 0.3.1 (2020-04-26)                  

  - Read in session tokens from shared credential files.
  - Fix handling of dates when used as arguments to CloudWatch and other
    APIs. Previously the operation would submit the date in an
    inappropriate format.
  - Fix handling of profiles when specified for a specific service, e.g.
    paws::svc(config = list(credentials = list(profile =
    "my-profile"))). Previously the profile was not used to get
    credentials.
  - Fix handling of operations that return nothing -- return an empty
    object rather than failing.

                 Changes in version 0.3.0 (2020-03-28)                  

  - Add HTTP status codes to the error response when an operation fails,
    along with any other information returned by AWS about the error.
  - Add support for S3 operation GetBucketLocation, which needs special
    handling.
  - Fix how paws.common provides request handlers to specific services
    (e.g. S3) so that fixes to handlers don't require re-installing any
    package other than paws.common.

                 Changes in version 0.2.6 (2020-02-23)
