-### Changes affecting backwards compatibility
+This is a bugfix release of version 0.19.0. No new features or breaking changes.
+The most important bugfixes are:
 
-- The stdlib module ``future`` has been renamed to ``sugar``.
-- ``macros.callsite`` is now deprecated. Since the introduction of ``varargs``
-  parameters this became unnecessary.
-- Anonymous tuples with a single element can now be written as ``(1,)`` with a
-  trailing comma. The underlying AST is ``nnkTupleConstr(newLit 1)`` for this
-  example. ``nnkTupleConstr`` is a new node kind your macros need to be able
-  to deal with!
-- Indexing into a ``cstring`` for the JS target is now mapped
-  to ``charCodeAt``.
-- Assignments that would "slice" an object into its supertype are now prevented
-  at runtime. Use ``ref object`` with inheritance rather than ``object`` with
-  inheritance to prevent this issue.
-- The ``not nil`` type annotation now has to be enabled explicitly
-  via ``{.experimental: "notnil"}`` as we are still not pleased with how this
-  feature works with Nim's containers.
-- The parser now warns about inconsistent spacing around binary operators as
-  these can easily be confused with unary operators. This warning will likely
-  become an error in the future.
-- The ``'c`` and ``'C'`` suffix for octal literals is now deprecated to
-  bring the language in line with the standard library (e.g. ``parseOct``).
-- The dot style for import paths (e.g ``import path.to.module`` instead of
-  ``import path/to/module``) has been deprecated.
+- ``spawn`` can handle the empty seqs/strings that are internally
+  represented as ``nil``.
+- The most pressing bugs of the documentation generator have been fixed.
+- async streaming of the httpclient has been fixed.
 
-#### Breaking changes in the standard library
-
-- ``re.split`` for empty regular expressions now yields every character in
-  the string which is what other programming languages chose to do.
-- The returned tuple of ``system.instantiationInfo`` now has a third field
-  containing the column of the instantiation.
-
-- ``cookies.setCookie`` no longer assumes UTC for the expiration date.
-- ``strutils.formatEng`` does not distinguish between ``nil`` and ``""``
-  strings anymore for its ``unit`` parameter. Instead the space is controlled
-  by a new parameter ``useUnitSpace``.
-
-- The ``times.parse`` and ``times.format`` procs have been rewritten.
-  The proc signatures are the same so it should generally not break anything.
-  However, the new implementation is a bit stricter, which is a breaking change.
-  For example ``parse("2017-01-01 foo", "yyyy-MM-dd")`` will now raise an error.
-
-- ``proc `-`*(a, b: Time): int64`` in the ``times`` module has changed return type
-  to ``times.Duration`` in order to support higher time resolutions.
-  The proc is no longer deprecated.
-
-- The ``times.Timezone`` is now an immutable ref-type that must be initialized
-  with an explicit constructor (``newTimezone``).
-
-- ``posix.Timeval.tv_sec`` has changed type to ``posix.Time``.
-
-- ``math.`mod` `` for floats now behaves the same as ``mod`` for integers
-  (previously it used floor division like Python). Use ``math.floorMod`` for the old behavior.
-
-- For string inputs, ``unicode.isUpper`` and ``unicode.isLower`` now require a
-  second mandatory parameter ``skipNonAlpha``.
-
-- For string inputs, ``strutils.isUpperAscii`` and ``strutils.isLowerAscii`` now
-  require a second mandatory parameter ``skipNonAlpha``.
-
-- ``osLastError`` is now marked with ``sideEffect``
-- The procs ``parseHexInt`` and ``parseOctInt`` now fail on empty strings
-  and strings containing only valid prefixes, e.g. "0x" for hex integers.
-
-- ``terminal.setCursorPos`` and ``terminal.setCursorXPos`` now work correctly
-  with 0-based coordinates on POSIX (previously, you needed to use
-  1-based coordinates on POSIX for correct behaviour; the Windows behaviour
-  was always correct).
-
-- ``lineInfoObj`` now returns absolute path instead of project path.
-  It's used by ``lineInfo``, ``check``, ``expect``, ``require``, etc.
-
-- ``net.sendTo`` no longer returns an int and now raises an ``OSError``.
-- `threadpool`'s `await` and derivatives have been renamed to `blockUntil`
-  to avoid confusions with `await` from the `async` macro.
-
-
-#### Breaking changes in the compiler
-
-- The undocumented ``#? braces`` parsing mode was removed.
-- The undocumented PHP backend was removed.
-- The default location of ``nimcache`` for the native code targets was
-  changed. Read [the compiler user guide](https://nim-lang.org/docs/nimc.html#generated-c-code-directory)
-  for more information.
-
-### Library additions
-
-- ``re.split`` now also supports the ``maxsplit`` parameter for consistency
-  with ``strutils.split``.
-- Added ``system.toOpenArray`` in order to support zero-copy slicing
-  operations. This is currently not yet available for the JavaScript target.
-- Added ``getCurrentDir``, ``findExe``, ``cpDir`` and  ``mvDir`` procs to
-  ``nimscript``.
-- The ``times`` module now supports up to nanosecond time resolution when available.
-- Added the type ``times.Duration`` for representing fixed durations of time.
-- Added the proc ``times.convert`` for converting between different time units,
-  e.g days to seconds.
-- Added the proc ``algorithm.binarySearch[T, K]`` with the ```cmp``` parameter.
-- Added the proc ``algorithm.upperBound``.
-- Added inverse hyperbolic functions, ``math.arcsinh``, ``math.arccosh`` and ``math.arctanh`` procs.
-- Added cotangent, secant and cosecant procs ``math.cot``, ``math.sec`` and ``math.csc``; and their hyperbolic, inverse and inverse hyperbolic functions, ``math.coth``, ``math.sech``, ``math.csch``, ``math.arccot``, ``math.arcsec``, ``math.arccsc``, ``math.arccoth``, ``math.arcsech`` and ``math.arccsch`` procs.
-- Added the procs ``math.floorMod`` and ``math.floorDiv`` for floor based integer division.
-- Added the procs ``rationals.`div```, ``rationals.`mod```, ``rationals.floorDiv`` and ``rationals.floorMod`` for rationals.
-- Added the proc ``math.prod`` for product of elements in openArray.
-- Added the proc ``parseBinInt`` to parse a binary integer from a string, which returns the value.
-- ``parseOct`` and ``parseBin`` in parseutils now also support the ``maxLen`` argument similar to ``parseHexInt``.
-- Added the proc ``flush`` for memory mapped files.
-- Added the ``MemMapFileStream``.
-- Added a simple interpreting event parser template ``eventParser`` to the ``pegs`` module.
-- Added ``macros.copyLineInfo`` to copy lineInfo from other node.
-- Added ``system.ashr`` an arithmetic right shift for integers.
-
-- Added `split`, `splitWhitespace`, `size`, `alignLeft`, `align`,
-  `strip`, `repeat` procs and iterators to `unicode.nim`.
-
-### Library changes
-
-- ``macros.astGenRepr``, ``macros.lispRepr`` and ``macros.treeRepr``
-  now escapes the content of string literals consistently.
-- ``macros.NimSym`` and ``macros.NimIdent`` is now deprecated in favor
-  of the more general ``NimNode``.
-- ``macros.getImpl`` now includes the pragmas of types, instead of omitting them.
-- ``macros.hasCustomPragma`` and ``macros.getCustomPragmaVal`` now
-  also support ``ref`` and ``ptr`` types, pragmas on types and variant
-  fields.
-- ``system.SomeReal`` is now called ``SomeFloat`` for consistency and
-  correctness.
-- ``algorithm.smartBinarySearch`` and ``algorithm.binarySearch`` is
-  now joined in ``binarySearch``. ``smartbinarySearch`` is now
-  deprecated.
-- The `terminal` module now exports additional procs for generating ANSI color
-  codes as strings.
-- Added the parameter ``val`` for the ``CritBitTree[int].inc`` proc.
-- An exception raised from a ``test`` block of ``unittest`` now shows its type in
-  error message.
-- The ``compiler/nimeval`` API was rewritten to simplify the "compiler as an
-  API". Using the Nim compiler and its VM as a scripting engine has never been
-  easier. See ``tests/compilerapi/tcompilerapi.nim`` for an example of how to
-  use the Nim VM in a native Nim application.
-- Added the parameter ``val`` for the ``CritBitTree[T].incl`` proc.
-- The proc ``tgamma`` was renamed to ``gamma``. ``tgamma`` is deprecated.
-- The ``pegs`` module now exports getters for the fields of its ``Peg`` and ``NonTerminal``
-  object types. ``Peg``s with child nodes now have the standard ``items`` and ``pairs``
-  iterators.
-- The ``accept`` socket procedure defined in the ``net`` module can now accept
-  a nil socket.
-
-- In `strutils` empty strings now no longer matched as substrings anymore.
-
-### Language additions
-
-- Vm suport for float32<->int32 and float64<->int64 casts was added.
-
-
-### Language changes
-
-- The `importcpp` pragma now allows importing the listed fields of generic
-  C++ types. Support for numeric parameters have also been added through
-  the use of `static[T]` types.
-  (#6415)
-
-- Native C++ exceptions can now be imported with `importcpp` pragma.
-  Imported exceptions can be raised and caught just like Nim exceptions.
-  More details in language manual.
-
-- ``nil`` for strings/seqs is finally gone. Instead the default value for
-  these is ``"" / @[]``. Use ``--nilseqs:on`` for a transition period.
-
-- Accessing the binary zero terminator in Nim's native strings
-  is now invalid. Internally a Nim string still has the trailing zero for
-  zero-copy interoperability with ``cstring``. Compile your code with the
-  new switch ``--laxStrings:on`` if you need a transition period.
-
-- The command syntax now supports keyword arguments after the first comma.
-
-- Thread-local variables can now be declared inside procs. This implies all
-  the effects of the ``global`` pragma.
-
-- Nim now supports the ``except`` clause in the export statement.
-
-- Range float types, example ``range[0.0 .. Inf]``. More details in language manual.
-- The ``{.this.}`` pragma has been deprecated. It never worked within generics and
-  we found the resulting code harder to read than the more explicit ``obj.field``
-  syntax.
-- "Memory regions" for pointer types have been deprecated, they were hardly used
-  anywhere. Note that this has **nothing** to do with the ``--gc:regions`` switch
-  of managing memory.
-
-- The exception hierarchy was slightly reworked, ``SystemError`` was renamed to
-  ``CatchableError`` and is the new base class for any exception that is guaranteed to
-  be catchable. This change should have minimal impact on most existing Nim code.
-
-
-### Tool changes
-- `jsondoc` now include a `moduleDescription` field with the module
-  description. `jsondoc0` shows comments as it's own objects as shown in the
-  documentation.
-
-- ``jsondoc2`` has been renamed ``jsondoc``, similar to how ``doc2`` was renamed
-  ``doc``. The old ``jsondoc`` can still be invoked with ``jsondoc0``.
-
-### Compiler changes
-
-- The VM's instruction count limit was raised to 3 million instructions in
-  order to support more complex computations at compile-time.
-
-- Support for hot code reloading has been implemented for the JavaScript
-  target. To use it, compile your code with `--hotCodeReloading:on` and use a
-  helper library such as LiveReload or BrowserSync.
-
-- A new compiler option `--cppCompileToNamespace` puts the generated C++ code
-  into the namespace "Nim" in order to avoid naming conflicts with existing
-  C++ code. This is done for all Nim code - internal and exported.
-
-- Added ``macros.getProjectPath`` and ``ospaths.putEnv`` procs to Nim's virtual
-  machine.
-
-- The ``deadCodeElim`` option is now always turned on and the switch has no
-  effect anymore, but is recognized for backwards compatibility.
-
-- ``experimental`` is now a pragma / command line switch that can enable specific
-  language extensions, it is not an all-or-nothing switch anymore.
-
-- Nintendo Switch was added as a new platform target. See [the compiler user guide](https://nim-lang.org/docs/nimc.html)
-  for more info.
-
-- macros.bindSym now capable to accepts not only literal string or string constant expression.
-  bindSym enhancement make it also can accepts computed string or ident node inside macros /
-  compile time functions / static blocks. Only in templates / regular code it retains it's old behavior.
-  This new feature can be accessed via {.experimental: "dynamicBindSym".} pragma/switch.
-
-- On Posix systems the global system wide configuration is now put under ``/etc/nim/nim.cfg``,
-  it used to be ``/etc/nim.cfg``. Usually it does not exist, however.
-
-- On Posix systems the user configuration is now looked under ``$XDG_CONFIG_HOME/nim/nim.cfg``
-  (if ``XDG_CONFIG_HOME`` is not defined, then under ``~/.config/nim/nim.cfg``). It used to be
-  ``$XDG_CONFIG_DIR/nim.cfg`` (and ``~/.config/nim.cfg``).
-
-  Similarly, on Windows, the user configuration is now looked under ``%APPDATA%/nim/nim.cfg``.
-  This used to be ``%APPDATA%/nim.cfg``.
