Is BS 449 still current?

I'm curious to know if the BS 449 standard is still considered current in today's rapidly evolving landscape of cryptocurrency and finance. Given the dynamic nature of this industry, it's crucial to ensure that we're adhering to the most up-to-date regulations and standards. Could you please clarify if this standard is still widely recognized and implemented, or if there are more recent or more suitable alternatives that should be adopted? Your insights into this matter would be greatly appreciated.
