+## v1.0.4
+### 2024-04-05
+
+This version of HOSS implements `black` code formatting across the repository.
+There should be no functional changes in the service.

 ## v1.0.3
-### 2024-3-29
+### 2024-03-29
 
-This version of HOSS handles the error in the crs_wkt attribute in ATL19 where the 
-north polar crs variable has a leading iquotation mark escaped by back slash in the 
-crs_wkt attribute. This causes errors when the projection is being interpreted from 
-the crs variable attributes.

-### 2024-2-26

 This version of HOSS correctly handles edge-aligned geographic collections by
 adding the attribute `cell_alignment` with the value `edge` to `hoss_config.json`

+### pre-commit hooks:
+
+This repository uses [pre-commit](https://pre-commit.com/) to enable pre-commit
+checking the repository for some coding standard best practices. These include:
+
+* Removing trailing whitespaces.
+* Removing blank lines at the end of a file.
+* JSON files have valid formats.
+* [ruff](https://github.com/astral-sh/ruff) Python linting checks.
+* [black](https://black.readthedocs.io/en/stable/index.html) Python code
+  formatting checks.
+
+To enable these checks:
+
+```bash
+# Install pre-commit Python package as part of test requirements:
+pip install -r tests/pip_test_requirements.txt
+
+# Install the git hook scripts:
+pre-commit install
+
+# (Optional) Run against all files:
+pre-commit run --all-files
+```
+
+When you try to make a new commit locally, `pre-commit` will automatically run.
+If any of the hooks detect non-compliance (e.g., trailing whitespace), that
+hook will state it failed, and also try to fix the issue. You will need to
+review and `git add` the changes before you can make a commit.
+
+It is planned to implement additional hooks, possibly including tools such as
+`mypy`.
