Get the changelog of blade to help consumer with blade upgrades and checking release notes. Either for a specific version or a range of two versions,

Intent examples:
- help me with upgrades -> read \`package.json\` to get consumer's blade version to use it as \`fromVersion\` and then use \`toVersion\` as \`latest\` version (range)
- what was changed in x.x.x version? -> Just \`fromVersion\` (set isRange to false & omit toVersion)
- what was changed between x.x.x and y.y.y versions? -> \`fromVersion\` and \`toVersion\` (set isRange to true)
- what is the latest version of blade? -> \`fromVersion\` as \`latest\` (set isRange to false & omit toVersion)

You will provide high level summary of notable changes in this output format:

\`\`\`
