Fresh NY Times article from yesterday (archived, NYT usually paywalled I don't see why this article would not be):
https://web.archive.org/web/20240616172129/https://www.nytimes.com/interactive/2024/06/15/world/europe/ukraine-russia-ceasefire-deal.html
The 2022 spring peace talks. They also link pdf-s (downloadable from the archived page) 2 drafts of the treaty (first from March 17th, second from April 15th) and the Istanbul Communiqué. I upload the English version (Russian ones also dl-able).
The April 15th version essentially says:
- Ukraine is neutral (they detail this in depth)
- weapon restrictions
- some cosmetics (such as about National Socialism, and whatnot)
As for Crimea, Ukraine don't have to recognize it as Russia, no such point in the document, but it stays under Russian occupation (Article 8 implies this).
They mention a map in Article 2, 6 ,and 9, but that is nowhere to be found sadly. It seems about the territories which remain under Russian occupation. This would be very important to judge how favorable or not was this thing compared to current situation, and the proposals above.
