Requires the Github variable NIGHTLY_REPOSITORY to be set to the nightly release repository's name. (Already set to OpenVic-Simulation-nightly-builds)
Requires the Github secret NIGHTLY_REPOSITORY_TOKEN to be set.
Requires the Github variable NIGHTLY_CORE_VERSION to be set. (Already set to 0.1)
Requires the Github variable DEFAULT_COMMIT_HASH to an existing repository hash. (Already set to f6c94ddcb62c257f841051395d8511a454e091b7)

These templates follow semver:

• Template for alpha releases: MAJOR.MINOR.PATCH-alpha.COUNT.
• Template for beta releases: MAJOR.MINOR.PATCH-beta.COUNT.
• Template for release candidate releases: MAJOR.MINOR.PATCH-rc.COUNT.
• Template for full releases: MAJOR.MINOR.PATCH.
• Template for snapshot releases: MAJOR.MINOR.PATCH-snapshot.COUNT+SHA.
• Template for dev snapshot releases: MAJOR.MINOR.PATCH-snapshot.dev.COUNT+SHA.
• Automatically generates nightly releases: MAJOR.MINOR.PATCH-nightly.YYYY.MM.DD+SHA.

.PATCH is optional.
COUNT refers to how many of this release type there is with the release, so the first alpha for 0.1 would be 0.1-alpha.1, COUNT should be reset on the next major, minor, or patch change.

Tags must be pushed in this form for all except for nightly releases. The releases automatically generate the release notes with PRs since the last update. Full releases only consider the difference between non-prerelease releases. Alphas, betas, and release candidates don't consider snapshots or nightly releases. Snapshots don't consider nightly releases. And nightly releases consider every release.

Nightly releases will build their release notes based on the publish date of the releases of the last nightly build compared to the master's latest published release. (not github's latest, prereleases are included)
Nightly releases retrieve the MAJOR.MINOR.PATCH from NIGHTLY_CORE_VERSION.
Nightly releases only publish if a new commit (since the last nightly) which changes the output binary is found.

To disable nightly releases you can set the Github variable DISABLE_NIGHTLY_RELEASES to true.
To disable trigger releases via tags you can set the Github variable DISABLE_TAG_RELEASES to true.
To disable PR and master commit builds you can set the Github variable DISABLE_BUILDS to true.
