See issue + [#6223](https://github.com/nim-lang/Nim/issues/6223) for more details. + You can use ``substr(str, start, finish)`` to get the old behaviour back, + see [this commit](https://github.com/nim-lang/nimbot/commit/98cc031a27ea89947daa7f0bb536bcf86462941f) for an example. + +- ``strutils.split`` and ``strutils.rsplit`` with an empty string and a + separator now returns that empty string. + See issue [#4377](https://github.com/nim-lang/Nim/issues/4377). + +- Arrays of char cannot be converted to ``cstring`` anymore, pointers to + arrays of char can! This means ``$`` for arrays can finally exist + in ``system.nim`` and do the right thing. This means ``$myArrayOfChar`` changed + its behaviour! Compile with ``-d:nimNoArrayToString`` to see where to fix your + code. + +- `reExtended` is no longer default for the `re` constructor in the `re` + module. + +- The behavior of ``$`` has been changed for all standard library collections. The + collection-to-string implementations now perform proper quoting and escaping of + strings and chars. + +- `newAsyncSocket` taking an `AsyncFD` now runs `setBlocking(false)` on the + fd. + +- ``mod`` and bitwise ``and`` do not produce ``range`` subtypes anymore. This + turned out to be more harmful than helpful and the language is simpler + without this special typing rule. + +- ``formatFloat``/``formatBiggestFloat`` now support formatting floats with zero + precision digits. The previous ``precision = 0`` behavior (default formatting) + is now available via ``precision = -1``. + +- Moved from stdlib into Nimble packages: + - [``basic2d``](https://github.com/nim-lang/basic2d) + _deprecated: use ``glm``, ``arraymancer``, ``neo``, or another package instead_ + - [``basic3d``](https://github.com/nim-lang/basic3d) + _deprecated: use ``glm``, ``arraymancer``, ``neo``, or another package instead_ + - [``gentabs``](https://github.com/lcrees/gentabs) + - [``libuv``](https://github.com/lcrees/libuv) + - [``numeric``](https://github.com/lcrees/polynumeric) + - [``poly``](https://github.com/lcrees/polynumeric) + - [``pdcurses``](https://github.com/lcrees/pdcurses) + - [``romans``](https://github.com/lcrees/romans) + - [``libsvm``](https://github.com/nim-lang/libsvm_legacy) + - [``joyent_http_parser``](https://github.com/nim-lang/joyent_http_parser) + +- Proc [toCountTable](https://nim-lang.org/docs/tables.html#toCountTable,openArray[A]) + now produces a `CountTable` with values correspoding to the number of occurrences + of the key in the input. It used to produce a table with all values set to `1`. + + Counting occurrences in a sequence used to be: + + ```nim + let mySeq = @[1, 2, 1, 3, 1, 4] + var myCounter = initCountTable[int]() + + for item in mySeq: + myCounter.inc item + ``` + + Now, you can simply do: + + ```nim + let + mySeq = @[1, 2, 1, 3, 1, 4] + myCounter = mySeq.toCountTable() + ``` + +- If you use ``--dynlibOverride:ssl`` with OpenSSL 1.0.x, you now have to + define ``openssl10`` symbol (``-d:openssl10``). By default OpenSSL 1.1.x is + assumed. + +- ``newNativeSocket`` is now named ``createNativeSocket``. + +- ``newAsyncNativeSocket`` is now named ``createAsyncNativeSocket`` + and it no longer raises an OS error but returns an ``osInvalidSocket`` when + creation fails. + +- The ``securehash`` module is now deprecated. Instead import ``std / sha1``. + +- The ``readPasswordFromStdin`` proc has been moved from the ``rdstdin`` + to the ``terminal`` module, thus it does not depend on linenoise anymore. + +#### Breaking changes in the compiler + +- ``\n`` is now only the single line feed character like in most + other programming languages. The new platform specific newline escape sequence is + written as ``\p``. This change only affects the Windows platform. + +- The overloading rules changed slightly so that constrained generics are + preferred over unconstrained generics. (Bug #6526) + +- We changed how array accesses "from backwards" like ``a[^1]`` or ``a[0..^1]`` are + implemented. These are now implemented purely in ``system.nim`` without compiler + support. There is a new "heterogeneous" slice type ``system.HSlice`` that takes 2 + generic parameters which can be ``BackwardsIndex`` indices. ``BackwardsIndex`` is + produced by ``system.^``. + This means if you overload ``[]`` or ``[]=`` you need to ensure they also work + with ``system.BackwardsIndex`` (if applicable for the accessors). + +- The parsing rules of ``if`` expressions were changed so that multiple + statements are allowed in the branches. We found few code examples that + now fail because of this change, but here is one: + +```nim +t[ti] = if exp_negative: '-' else: '+'; inc(ti) +``` + +This now needs to be written as: + +```nim +t[ti] = (if exp_negative: '-' else: '+'); inc(ti) +``` + +- The experimental overloading of the dot ``.`` operators now take + an ``untyped``` parameter as the field name, it used to be + a ``static[string]``. You can use ``when defined(nimNewDot)`` to make + your code work with both old and new Nim versions. + See [special-operators](https://nim-lang.org/docs/manual.html#special-operators) + for more information. + +- ``yield`` (or ``await`` which is mapped to ``yield``) never worked reliably + in an array, seq or object constructor and is now prevented at compile-time. + +### Library additions + +- **Added ``sequtils.mapLiterals`` for easier construction of array and tuple literals.** + +- Added ``system.runnableExamples`` to make examples in Nim's documentation easier + to write and test. The examples are tested as the last step of + ``nim doc``. + +- Implemented ``getIoHandler`` proc in the ``asyncdispatch`` module that allows + you to retrieve the underlying IO Completion Port or ``Selector[AsyncData]`` + object in the specified dispatcher. + +- For string formatting / interpolation a new module + called [strformat](https://nim-lang.org/docs/strformat.html) has been added + to the stdlib. + +- The `ReadyKey` type in the selectors module now contains an ``errorCode`` + field to help distinguish between ``Event.Error`` events. + +- Implemented an `accept` proc that works on a `SocketHandle` in + ``nativesockets``. + +- Added ``algorithm.rotateLeft``. + +- Added ``typetraits.$`` as an alias for ``typetraits.name``. + +- Added ``system.getStackTraceEntries`` that allows you to access the stack + trace in a structured manner without string parsing. + +- Added ``parseutils.parseSaturatedNatural``. + +- Added ``macros.unpackVarargs``. + +- Added support for asynchronous programming for the JavaScript backend using + the `asyncjs` module. + +- Added true color support for some terminals. Example: +```nim +import colors, terminal + +const Nim = "Efficient and expressive programming." + +var + fg = colYellow + bg = colBlue + int = 1.0 + +enableTrueColors() + +for i in 1..15: + styledEcho bgColor, bg, fgColor, fg, Nim, resetStyle + int -= 0.01 + fg = intensity(fg, int) + +setForegroundColor colRed +setBackgroundColor colGreen +styledEcho "Red on Green.", resetStyle +``` + +### Library changes + +- ``echo`` now works with strings that contain ``\0`` (the binary zero is not + shown) and ``nil`` strings are equal to empty strings. + +- JSON: Deprecated `getBVal`, `getFNum`, and `getNum` in favour of + `getBool`, `getFloat`, `getBiggestInt`. A new `getInt` procedure was also + added. + +- ``rationals.toRational`` now uses an algorithm based on continued fractions. + This means its results are more precise and it can't run into an infinite loop + anymore. + +- ``os.getEnv`` now takes an optional ``default`` parameter that tells ``getEnv`` + what to return if the environment variable does not exist. + +- The ``random`` procs in ``random.nim`` have all been deprecated. Instead use + the new ``rand`` procs. The module now exports the state of the random + number generator as type ``Rand`` so multiple threads can easily use their + own random number generators that do not require locking. For more information + about this rename see issue [#6934](https://github.com/nim-lang/Nim/issues/6934) + +- ``writeStackTrace`` is now proclaimed to have no IO effect (even though it does) + so that it is more useful for debugging purposes. + +- ``db_mysql`` module: ``DbConn`` is now a ``distinct`` type that doesn't expose the + details of the underlying ``PMySQL`` type. + +- ``parseopt2`` is now deprecated, use ``parseopt`` instead. + +### Language additions + +- It is now possible to forward declare object types so that mutually + recursive types can be created across module boundaries. See + [package level objects](https://nim-lang.org/docs/manual.html#package-level-objects) + for more information. + +- Added support for casting between integers of same bitsize in VM (compile time and nimscript). + This allows to, among other things, reinterpret signed integers as unsigned. + +- Custom pragmas are now supported using pragma ``pragma``, please see language + manual for details. + +- Standard library modules can now also be imported via the ``std`` pseudo-directory. + This is useful in order to distinguish between standard library and nimble package + imports: + + ```nim + import std / [strutils, os, osproc] + import someNimblePackage / [strutils, os] + ``` + +### Language changes + +- The **unary** ``<`` is now deprecated, for ``.. <`` use ``..<`` for other usages + use the ``pred`` proc. + +- Bodies of ``for`` loops now get their own scope: + +```nim +# now compiles: +for i in 0..4: + let i = i + 1 + echo i +``` + +- To make Nim even more robust the system iterators ``..`` and ``countup`` + now only accept a single generic type ``T``. This means the following code + doesn't die with an "out of range" error anymore: + +```nim +var b = 5.Natural +var a = -5 +for i in a..b: + echo i +``` + +- ``atomic`` and ``generic`` are no longer keywords in Nim. ``generic`` used to be + an alias for ``concept``, ``atomic`` was not used for anything. + +- The memory manager now uses a variant of the TLSF algorithm that has much + better memory fragmentation behaviour. According + to [http://www.gii.upv.es/tlsf/](http://www.gii.upv.es/tlsf/) the maximum + fragmentation measured is lower than 25%. As a nice bonus ``alloc`` and + ``dealloc`` became O(1) operations. + +- The compiler is now more consistent in its treatment of ambiguous symbols: + Types that shadow procs and vice versa are marked as ambiguous (bug #6693). + +- codegenDecl pragma now works for the JavaScript backend. It returns an empty + string for function return type placeholders. + +- Extra semantic checks for procs with noreturn pragma: return type is not allowed, + statements after call to noreturn procs are no longer allowed. + +- Noreturn proc calls and raising exceptions branches are now skipped during common type + deduction in ``if`` and ``case`` expressions. The following code snippets now compile: + ```nim + import strutils + let str = "Y" + let a = case str: + of "Y": true + of "N": false + else: raise newException(ValueError, "Invalid boolean") + let b = case str: + of nil, "": raise newException(ValueError, "Invalid boolean") + elif str.startsWith("Y"): true + elif str.startsWith("N"): false + else: false + let c = if str == "Y": true + elif str == "N": false + else: + echo "invalid bool" + quit("this is the end") + ``` + +- Pragmas now support call syntax, for example: ``{.exportc"myname".}`` and + ``{.exportc("myname").}`` + +- The ``deprecated`` pragma now supports a user-definable warning message for procs. + + ```nim + proc bar {.deprecated: "use foo instead".} = + return + + bar() + ``` + +### Tool changes + +- The ``nim doc`` command is now an alias for ``nim doc2``, the second version of + the documentation generator. The old version 1 can still be accessed + via the new ``nim doc0`` command. + +- Nim's ``rst2html`` command now supports the testing of code snippets via an RST + extension that we called ``:test:``:: + + ```rst + .. code-block:: nim + :test: + # shows how the 'if' statement works + if true: echo "yes" + ``` + +### Compiler changes + +### Bugfixes + +- Fixed "ReraiseError when using try/except within finally block" + ([#5871](https://github.com/nim-lang/Nim/issues/5871)) +- Fixed "Range type inference leads to counter-intuitive behvaiour" +
