I adjusted the 3.8.0 release notes .md and generated the PDF.

@DavidGoldwasser @wenyikuang We've been historically doing this for every release. The format is much better than what's displayed on the 3.8.0 release https://github.com/NREL/OpenStudio/releases/v3.8.0 which in this specific case is purely the automated github changelog, not even sorted by importance or removing the Developer issues.

Can you please advise whether we keep doing this going forward?

  • If so, friendly reminder to everyone that we should keep the habit of populating the TDB release notes with major changes at least, and to remind to produce the Release Notes at release time.
  • If not, we should at least clean and reorganize the automatically generated Github changelog on the release page.

@jmarrec I like the more advanced release notes that are https://github.com/NREL/OpenStudio/blob/develop/developer/doc/ReleaseNotes/

It's probably my fault that the release notes here https://github.com/NREL/OpenStudio/releases/tag/v3.8.0 don't look like they did for 3.7 https://github.com/NREL/OpenStudio/releases/tag/v3.7.0

I would like to automate builds more for 3.10 and later but we'll always have some hand written narratives. I can try to write those throughout the 6 month cycle and not wait to drop in at the end. But when we can pull in auto-generated change log that seems nice.

# OpenStudio Version 3.9.0

_Release Notes_ - _TDB_

These release notes describe version 3.9.0 of the OpenStudio SDK developed by the National Renewable Energy Laboratory (NREL), Buildings and Thermal Sciences Center, Commercial Buildings Research Group, Tools Development Section, and associated collaborators. The notes are organized into the following sections:

- Overview
- Where to Find OpenStudio Documentation
- Installation Notes
- OpenStudio SDK: Changelog

# Overview

As of April 2020, development and distribution of the OpenStudioApplication and the SketchUp plugin have transitioned to the OpenStudio Coalition, who is independently managing and distributing the software through its own [openstudiocoalition/OpenStudioApplication](https://github.com/openstudiocoalition/OpenStudioApplication) repository. The OpenStudio SDK is continuing to be actively developed and distributed by NREL and is released two times per year, through a spring and a fall release.

Below is the list of components that is included in this SDK installer:

__**OpenStudio SDK 3.9.0**__
- EnergyPlus
- Command Line Interface (CLI)
- Radiance
- Ruby API
- Python API
- C++ SDK

**Note** that [PAT](https://github.com/NREL/OpenStudio-PAT) is not included in either the SDK or the OpenStudio Coalition's Application installers. You will need to install PAT separately which is distributed on the [OpenStudio-PAT](https://github.com/NREL/OpenStudio-PAT) GitHub page.

# Where to Find OpenStudio SDK Documentation

- OpenStudio SDK release documentation, including these release notes, tutorials, and other user documentation, is available at [https://www.openstudio.net/](https://www.openstudio.net/.)

# OpenStudio SDK: Changelog

The 3.9.0 is a **major** release. This update includes several new features, performance improvements, and bug fixes.

## C++ Workflow code

As of OpenStudio SDK 3.7.0 a re-written workflow written in C++ is used by default in place of the Ruby based Workflow Gem that had been used in the past. This enhancement is in support of Python measures being used in an OpenStudio workflow, including mixed language workflows that include both Ruby Measures and Python Measures. If you need to use the older Workflow Gem implementation, you can do that by using the `classic` subcommand after `openstudio`. `classic` will be deprecated in a future version of OpenStudio.

## Python Bindings

As of OpenStudio SDK 3.2.0, Python bindings are officially supported and distributed through Python Package Index (PyPI). To install, users will need to have Python3 installed along with pip and simply run the following command in a terminal window.

`pip install openstudio==3.9.0`

Please see [openstudio on PyPi](https://pypi.org/project/openstudio/) for further instructions on how to install. Users can also visit the test channel at [openstudio on TestPyPi](https://test.pypi.org/project/openstudio/) to install development bindings.

You can also refer to the [OpenStudio SDK Python Binding Version Compatibility Matrix](https://github.com/NREL/OpenStudio/wiki/OpenStudio-SDK-Python-Binding-Version-Compatibility-Matrix) to see the list of supported platforms and python versions.

## New Features, Major Fixes and API-breaking changes

* [#5242](https://github.com/NREL/OpenStudio/pull/5242) - Update to EnergyPlus v24.2.0a
* To see the full list of additions and changes, refer to the issue [#5240](https://github.com/NREL/OpenStudio/issues/5240)

* [#5237](https://github.com/NREL/OpenStudio/pull/5237) - Updates to Controller:OutdoorAir
* This PR implements the fields `Humidistat Control Zone Name` and `Electronic Enthalpy Limit Curve`
* `ControllerOutdoorAir` has two API-breaking changes for `High Humidity Outdoor Air Flow Ratio` and `Control High Indoor Humidity Based on Outdoor Humidity Ratio`. These fields are now-required, so the getters no longer return an optional
* `getHighHumidityOutdoorAirFlowRatio` (`boost::optional<double>` to `double`)
* `getControlHighIndoorHumidityBasedOnOutdoorHumidityRatio` (`boost::optional<bool>` to `bool`)

I also adjusted the Release_Notes template.md to conform to latest format, and added some quick pandoc settings to set the title, margin and colors. And most importantly, a reminder of how to generate the PDF from the Markdown file.
