+## Changes affecting backward compatibility
 
-## Standard library additions and changes
-
-- Make `{.requiresInit.}` pragma to work for `distinct` types.
-
-- Added a macros `enumLen` for returning the number of items in an enum to the
-  `typetraits.nim` module.
-
-- `prelude` now works with the JavaScript target.
-
-- Added `almostEqual` in `math` for comparing two float values using a machine epsilon.
-
-- The JSON module can now handle integer literals and floating point literals of
-  arbitrary length and precision.
-  Numbers that do not fit the underlying `BiggestInt` or `BiggestFloat` fields are
-  kept as string literals and one can use external BigNum libraries to handle these.
-  The `parseFloat` family of functions also has now optional `rawIntegers` and
-  `rawFloats` parameters that can be used to enforce that all integer or float
-  literals remain in the "raw" string form so that client code can easily treat
-  small and large numbers uniformly.
-
-- Added an overload for the `collect` macro that inferes the container type based
-  on the syntax of the last expression. Works with std seqs, tables and sets.
-
-- Added `randState` template that exposes the default random number generator.
-  Useful for library authors.
-
-- Added std/enumutils module containing `genEnumCaseStmt` macro that generates
-  case statement to parse string to enum.
-
-- Removed deprecated `iup` module from stdlib, it has already moved to
-  [nimble](https://github.com/nim-lang/iup).
-
-- `nodejs` backend now supports osenv: `getEnv`, `putEnv`, `envPairs`, `delEnv`, `existsEnv`.
-
-- Added `cmpMem` to `system`.
-
-- `doAssertRaises` now correctly handles foreign exceptions.
-
-- Added `asyncdispatch.activeDescriptors` that returns the number of currently
-  active async event handles/file descriptors.
-
-- ``--gc:orc`` is now 10% faster than previously for common workloads. If
-  you have trouble with its changed behavior, compile with ``-d:nimOldOrc``.
-
-
-- `os.FileInfo` (returned by `getFileInfo`) now contains `blockSize`,
-  determining preferred I/O block size for this file object.
-
-- `repr` now doesn't insert trailing newline; previous behavior was very inconsistent,
-  see #16034. Use `-d:nimLegacyReprWithNewline` for previous behavior.
 
-- Added `**` to jsffi.
-
-- `writeStackTrace` is available in JS backend now.
-
-- Added `decodeQuery` to `std/uri`.
-- `strscans.scanf` now supports parsing single characters.
-- `strscans.scanTuple` added which uses `strscans.scanf` internally, returning a tuple which can be unpacked for easier usage of `scanf`.
-
-- Added `setutils.toSet` that can take any iterable and convert it to a built-in set,
-  if the iterable yields a built-in settable type.
-
-- Added `math.isNaN`.
-
-- `echo` and `debugEcho` will now raise `IOError` if writing to stdout fails.  Previous behavior
-  silently ignored errors.  See #16366.  Use `-d:nimLegacyEchoNoRaise` for previous behavior.
-
-- Added `math.copySign`.
-- Added new operations for singly- and doubly linked lists: `lists.toSinglyLinkedList`
-  and `lists.toDoublyLinkedList` convert from `openArray`s; `lists.copy` implements
-  shallow copying; `lists.add` concatenates two lists - an O(1) variation that consumes
-  its argument, `addMoved`, is also supplied.
-
-- Added `sequtils` import to `prelude`.
-
-- Added `euclDiv` and `euclMod` to `math`.
-- Added `httpcore.is1xx` and missing HTTP codes.
-- Added `jsconsole.jsAssert` for JavaScript target.
+## Standard library additions and changes
 
 
 ## Language changes
 
-- `nimscript` now handles `except Exception as e`.
-
-- The `cstring` doesn't support `[]=` operator in JS backend.
-
-- nil dereference is not allowed at compile time. `cast[ptr int](nil)[]` is rejected at compile time.
-
 
 ## Compiler changes
 
-- Added `--declaredlocs` to show symbol declaration location in messages.
-
-- Source+Edit links now appear on top of every docgen'd page when
-  `nim doc --git.url:url ...` is given.
-
-- Added `nim --eval:cmd` to evaluate a command directly, see `nim --help`.
-
-- VM now supports `addr(mystring[ind])` (index + index assignment)
-- Type mismatch errors now show more context, use `-d:nimLegacyTypeMismatch` for previous
-  behavior.
-
 
 ## Tool changes
 
-- The rst parser now supports markdown table syntax.
-  Known limitations:
-  - cell alignment is not supported, i.e. alignment annotations in a delimiter
-    row (`:---`, `:--:`, `---:`) are ignored,
-  - every table row must start with `|`, e.g. `| cell 1 | cell 2 |`.
