1.5.0 20241027

BF: Build: Review and optimization
CR: Service: Optimization of the configuration via environment variables
    Simplifies the provision as a container.
    - XMEX_URI_XPATH_DELIMITER: XPath delimiter in the URI (!)
    - XMEX_STORAGE_DIRECTORY: Directory of the data storage (./data)
    - XMEX_STORAGE_QUANTITY: Maximum number of files in data storage (65535)
    - XMEX_STORAGE_SPACE: Maximum data size of files in data storage in bytes (256 *1024)
    - XMEX_STORAGE_EXPIRATION: Maximum idle time of the files in seconds (15 *60)
    - XMEX_STORAGE_REVISION_TYPE: Basis of the revision number (1)
    - XMEX_DEBUG_MODE: Activates debug mode for unit tests (off)
    - XMEX_CONTAINER_MODE: Activates debug mode for unit tests (off)
CR: Request: Configurable XPath delimiter of the URI
    XPath delimiter for the URI is not automatically the first symbol.
    The uniform standard is the exclamation mark !
CR: Request: Omission of XPath via query string
    The XPath includes the query string as part of the path.
CR: Request: Uniform identifier question mark for Base64 and hex encoded paths
    old: /xmex!Base64:Ly9ib29rW2xhc3QoKV0vY2hhcHRlcltsYXN0KCld
    new: /xmex!?Ly9ib29rW2xhc3QoKV0vY2hhcHRlcltsYXN0KCld
    old: /xmex!0x282f626f6f6b73292f2f6c6173743a3a6265666f7265
    new: /xmex!?282f626f6f6b73292f2f6c6173743a3a6265666f7265
CR: Storage: Optimization of the cleanup
    To reduce the execution time of the requests, the cleanup only runs every
    minute. Parallel cleanups due to parallel requests cannot be excluded, but
    should not be a problem.
CR: Storage: Review and optimization
    - The name now allows word characters and minus, if the minus is not at the
      beginning and not at the end.
    - The encoding of the file name has been optimized so that case-sensitive
      also works in case-insensitive file systems (like Windows).
    - Added the consideration of the root element. Name of storage and name of
      root element define the case-sensitive name of the storage in the file
      system. This means that the different spelling of the root element creates
      different storages.
CR: Service: Review of revision management
    - Added option XMEX_STORAGE_REVISION_TYPE
      Defines what the revision which is used in the attributes ___rev and
      ___uid should be based on. With 'serial', an auto incremental integer is
      used. The default value is 'timestamp', which uses an alphanumeric
      timestamp.
    - Omission of the response header Connection-Unique
      The client can manage this better for itself. The created ___uid attribute
      of the elements are now based on the storage revision ___rev attribute.
    - Omission of the response header Storage-Effects
    - Switch to response header Storage-Revision with the number of changes
      schema: revision/number of changes, e.g. Storage-Revision: 123/45
      without changes Storage-Revision: 123/0
CR: Service: Review and optimization of CONNECT
    - Storage must be initialized mandatory with CONNECT before it can be used.
    - Added alternative alias method TOUCH, if CONNECT is not allowed.
    - Added alternative PUT without XPath, if CONNECT and TOUCH is not allowed.
CR: Service: Review and optimization of OPTIONS
    - Omission of the response header Storage-Effects.
    - Omission as an alternative to CONNECT.
      If CONNECT is not allowed use TOUCH.
      If TOUCH is not allowed use PUT without XPath.
CR: Service: Review and optimization of GET
    - Requests with an XPath that does not address a target are responded to
      with status 204 (No Content). Previously it was status 404, but 404 now
      refers exclusively to the storage file.
CR: Service: Review and optimization of DELETE, PATCH, PUT
    - Requests with XPath that do not address a target are responded with status
      304 (Not Modified), as the request does not change the storage file.
CR: Service: Review and optimization of POST
    - Extension of the element output by the attribute encoding to specify the
      response header Content-Type.
CR: Service: Optimization of data storage
    - Unnecessary spaces and indentations are removed.
CR: Test: Added option XMEX_DEBUG_MODE
    - Forces the use of the automatic incremental revision type
    - Adds hashed headers for request, response and storage to the response
    - Storage files are also created with the file extension xml and formatted
    - Storage files are saved in versions
CR: Test: Review and optimization
    - Switch to the use of XMEX_DEBUG_MODE
    - Switch to new hashes in the response header
      Trace-Request-Hash, Trace-Request-Header-Hash, Trace-Request-Data-Hash
      Trace-Response-Hash, Trace-Response-Header-Hash, Trace-Response-Data-Hash
      Trace-Storage-Hash
    - Integration of JetBrains HTTP Client CLI
CR: Docker: Added support as Docker image

BF: Build: Optimization / correction of the release info process
CR: Build: Releases are now only available on the release page
CR: OpenAPI: Added the missing OpenAPI Specification
CR: Project: Moved repository to xml-micro-exchange-php
NT: Harmonization of version numbers for the different implementations
    Major and minor describe the API, patch refers to the implementation.
    The version of OpenAPI therefore only uses major and minor, patch is always 0.
