| ### Backwards Compatibility | ||

| ink! and pallet_contracts are the projects under active development. As contracts API functions evolve to their newer versions, we need to introduce them in ink! in a way that still keeps current *MAJOR* ink! version compatible with elder substrate nodes built with the pallet_contracts version having not this new functionality. |

| ink! and pallet_contracts are the projects under active development. As contracts API functions (denoted by the `seal_*` prefix) evolve to their newer versions, we need to introduce them in ink! in a way that still keeps current *MAJOR* ink! version compatible with older Substrate nodes. These older nodes may have a version of the Contracts pallet which does not support new seal APIs. |

| In order to achieve this, please stick to the following workflow. | ||

| Imagine there is a `[seal0] function()` in pallet\_contracts API and our `ink_env::function()` uses its import under the hood. |

| 1. Mark the old `ink_env::function()` (which depends on the imported `[seal0]` function) with the `#[deprecated]` attribute. | ||
| Please, specify the `since` field with the ink! version since which this function is deprecated in favor of the newest one, and is left there only for the backwards compatibility purposes. Specifing some additional helpful info in the `note` field could also be a good idea. | ||
| 2. Name the new function (which depends on the `[seal1] function()`) somehow descriptive like `ink_env::function_whats_special()`. |

Mark all of these as 1, the markdown render will handle the numbering

well, this is an optional feature, btw it will work so even if you mark it with a randomly assigned set of integer numbers as well. However, I think it's good to have it numbered properly in the source itself.
