# Get the most recent tag
git describe --tags --abbrev=0

# Get unreleased commits since last tag
git log --oneline --no-merges $(git describe --tags --abbrev=0 2>/dev/null || echo "")..HEAD

# Get commits between two tags
git log --oneline --no-merges <prev-tag>..<current-tag>

# Get tag creation date
git log -1 --format=%ai <tag-name>

Loop Through All Tags

ALL_TAGS=$(git tag --sort=-version:refname)

for tag in $ALL_TAGS; do
  PREV_TAG=$(git describe --tags --abbrev=0 $tag^ 2>/dev/null || echo "")
  COMMITS=$(git log --oneline --no-merges $PREV_TAG..$tag)
  echo "Version $tag:"
  echo "$COMMITS"
  echo "---"
done
