+=========
+Changelog
+=========
+
+Version 0.1.17
+--------------
+
+- Added detection label mapping for the ``phase1`` output to rename ``elephant_savanna`` to ``elephant``
+  to be consistent with the ``mvp`` output labels.
+- Added rounding to the WIC predicted confidence to 4 decimal points in the print and JSON outputs.
+- Added to the documentation the list of supported class labels for each model configuration.
+- Added platform detection code to detect macOS and reduce the batch size of WIC models with the
+  MVP model to 1 (added to Known Issues).
+- Added three new environment variables to allow specifying the model configuration for the ``WIC``,
+  ``LOC``, and ``AGG``, respectively: ``WIC_CONFIG``, ``LOC_CONFIG``, ``AGG_CONFIG``.  If unset, it
+  uses the global config and behavior as specified by the ``CONFIG`` environment variable.  The TILE
+  module does not have different settings dependent on the model configuration.
+- Added a new environment variable to allow for faster but less accurate results: ``FAST``.  If unset, it
+  uses the standard tile extraction behavior for grid1 and grid2.  Turning this flag on will dramatically
+  speed up inference by processing approximately half of the number of tiles per image.
+- Added ``CHANGELOG.rst`` and ``ISSUES.rst``.
+- Modified documentation strings in a few places for clarity and correctness.
+
+Version 0.1.16
+--------------
+
+*Alpha version of Scoutbot, with all Phase 1 and MVP functionality and pre-trained models included*

+============
+Known Issues
+============
+
+- Non-determinism and ONNX Runtime prediction failure on macOS when using MVP WIC
+  model and a batch size greater than 1.  The code will automatically recude the
+  batch size to 1 for this configuration and applicable environments.

    - ``WIC_BATCH_SIZE`` (default: 256)
       The configuration setting for how many tiles to send to the GPU in a single batch during the WIC
       prediction (forward inference).  The LOC model has a fixed batch size (16 for ``phase1`` and
       32 for ``mvp``) and cannot be adjusted.  This setting can be used to control how fast the pipeline
       runs, as a trade-off of faster compute for more memory usage.  It is highly suggested to set this
       value as high as possible to fit into the GPU.
+   - ``FAST`` (default: not set)
+      A flag that can be set to turn off extracting the second grid of tiles.  Defaults to "not set", which
+      translates to the standard process of extracting all tiles for grid1 and grid2.  Setting this
+      value to anything will turn off grid2 and results in faster (but less accurate) detections
+      (e.g., ``FAST=1``).
    - ``VERBOSE`` (default: not set)
       A verbosity flag that can be set to turn on debug logging.  Defaults to "not set", which translates
-      to no debug logging.

+Supported Objects of Interest
+-----------------------------
+
+The ONNX models are pre-configured to support a specific batch size and will predict specific species in
+the final detection results.  The input sizes are defined explicitly when they cannot be changed, but the
+``WIC`` model's inputs can be balanced using the environment variable ``WIC_BATCH_SIZE``.  The outputs of
+the pipeline is a collection of bounding boxes, confidence values, and class labels.  Some of the labels
+are not clean and are mapped, for convience, when the final detection labels are created.  Below are the
+supported species for each model:
+
+   - Phase 1: ``phase1``
+      - `elephant_savanna`
+      - - mapped to: `elephant`
