 ## Our set of commands is evolving [[toc](#table-of-content)]
-As usual, new release rhyms with changes to commands!
 
 ### New commands [[toc](#table-of-content)]
 ### Changes to existing commands [[toc](#table-of-content)]
+
+#### `with-env` [[toc](#table-of-content)]
+
+::: warning Breaking change
+See a full overview of the [breaking changes](#breaking-changes-toc)
+:::
+
+The enviroment variable list form of `with-env` is now deprecated aftter [#12523](https://github.com/nushell/nushell/pull/12523):
+```nushell
+with-env [X Y W Z] { $env.X }
+```
+
+Instead, one should use the record form:
+```nushell
+with-env { X: 'Y', W: 'Z' } { $env.X }
+```
+
+Additionally, setting the `PWD` variable through `with-env` is now disallowed.
+
+#### `load-env` [[toc](#table-of-content)]
+
+::: warning Breaking change
+See a full overview of the [breaking changes](#breaking-changes-toc)
+:::
+
+With [#12522](https://github.com/nushell/nushell/pull/12522), setting the `PWD` variable through `load-env` is now disallowed.
+
+
+#### `last` [[toc](#table-of-content)]
+
+::: warning Breaking change
+See a full overview of the [breaking changes](#breaking-changes-toc)
+:::
+
+To be consistent with `first` and other commands, `last` now errors if the input is empty ([#12478](https://github.com/nushell/nushell/pull/12478)).
+
+#### `drop` [[toc](#table-of-content)]
+
+::: warning Breaking change
+See a full overview of the [breaking changes](#breaking-changes-toc)
+:::
+
+With [#12479](https://github.com/nushell/nushell/pull/12479), `drop` will now error if the number of rows/columns is negative.
+
+#### `skip` [[toc](#table-of-content)]
+
+::: warning Breaking change
+See a full overview of the [breaking changes](#breaking-changes-toc)
+:::
+
+To be consistent with `take` and other commands, `skip` no longer accepts external streams as input ([#12559](https://github.com/nushell/nushell/pull/12559)).
+
+#### `group-by` [[toc](#table-of-content)]
+
+::: warning Breaking change
+See a full overview of the [breaking changes](#breaking-changes-toc)
+:::
+
+If a closure was used as the grouper for `group-by`, then errors inside the closure would previously be ignored. Instead, `group-by` would put the row/item under the `error` group.
+With [#12508](https://github.com/nushell/nushell/pull/12508), errors are no longer ignored and will immediately be bubbled up.
+
+#### `timeit` [[toc](#table-of-content)]
+
+::: warning Breaking change
+See a full overview of the [breaking changes](#breaking-changes-toc)
+:::
+
+After [#12465](https://github.com/nushell/nushell/pull/12465), the `timeit` command will no longer capture external command output, instead redirecting output to the terminal/stdio.
+
+#### `kill` [[toc](#table-of-content)]
+
+::: warning Breaking change
+See a full overview of the [breaking changes](#breaking-changes-toc)
+:::
+
+The `kill` command used to return a stream of values in certain cases. In [#12480](https://github.com/nushell/nushell/pull/12480) this was changed so that `kill` now always returns a single value (null or a string).
+
+#### `ls` [[toc](#table-of-content)]
+
+Instead of a single optional path, the `ls` command now takes a rest argument of paths ([#12327](https://github.com/nushell/nushell/pull/12327)). I.e., you can spread a list into `ls`:
+```nushell
+ls ...[directory1 directory2]
+```
+or simply `ls` multiple directories:
+```nushell
+ls directory1 directory2
+```
+
+#### `du` [[toc](#table-of-content)]
+
+In the `ls` PR ([#12327](https://github.com/nushell/nushell/pull/12327)), the same changes were also made to `du`. So, `du` now also takes a rest argument of paths.
+
+#### `into filesize` [[toc](#table-of-content)]
+
+Thanks to [@singh-priyank](https://github.com/singh-priyank) in [#12443](https://github.com/nushell/nushell/pull/12443), `into filesize` can now parse negative filesizes from strings.
+
+#### `explain` [[toc](#table-of-content)]
+
+With [#12432](https://github.com/nushell/nushell/pull/12432), the `type` column returned from `explain` should no longer contain `string` for every row.
