Additional Information

this test previously had surgery #12744

This test is very flaky, this change might help reducing the

but is still flaky (perhaps with a different error msg)

parsecfg: retain CRLF line breaks, fixes #12970 (#12971)

generic stack trace overriding mechanism (#12922)

* libbacktrace support

* switch to a generic stack trace overriding mechanism

When "nimStackTraceOverride" is defined, once of the imported modules
can register its own procedure to replace the default stack trace
generation by calling `registerStackTraceOverride(myOwnProc)`.

Tested with `./koch boot -d:release --debugger:native -d:nimStackTraceOverride --import:libbacktrace`
for the compiler itself and `./bin/nim c -r -f --stacktrace:off --debugger:native -d:nimStackTraceOverride --import:libbacktrace foo.nim`
for an external program.

* make the StackTraceOverrideProc {.noinline.}

c_fflush() the rawWrite() buffer (#12987)

Stack traces on an unbuffered stderr get out of sync with line-buffered
stdout - usually on Windows terminals or CI logs. This fixes it by
calling C's fflush() on the output buffer in the procedure used for
printing stack traces.

fixes disruptek/nimph#102 multi-level nim.cfg use (#13001) [backport]

--exception:goto switch for deterministic exception handling (#12977)

This implements "deterministic" exception handling for Nim based on goto instead of setjmp. This means raising an exception is much cheaper than in C++'s table based implementations. Supports hard realtime systems. Default for --gc:arc and the C target because it's generally a good idea and arc is all about deterministic behavior.

Note: This implies that fatal runtime traps are not catchable anymore! This needs to be documented.

compiler/ccgtypes: hide exportc proc unless it has dynlib (#13199)

fix #13211 relativePath("foo", ".") (#13213)

fixes a critical times.nim bug reported on IRC [backport] (#13216)

httpclient, maxredirects to Natural, newHttpClient/newAsyncHttpClient add headers argument instead of hardcoded empty (#13207)

added note to re constructor regarding performance (#13224)

Since I was new to regex I did not know that there is a compilation going on with ``re"[abc]"`` constructor and so I followed the other examples in the docs blindly, that is I just put the constructor directly in the arguments of match, find, etc., which was inside a loop and then wondered why my performance was so bad. Of course putting it outside the loop made it vastly more performant. People like me would benefit from the small note I added I would think :)

fix lots of bugs with parentDir, refs #8734 (#13236)

Unexport even more symbols (#13214)

* system/gc: don't export markStackAndRegisters

* compiler/cgen: unexport internal symbols

As these functions are Nim-specific walkaround against C's optimization
schemes, they don't serve any purpose being exported.

* compiler/cgen: don't export global var unless marked

* compiler/ccgthreadvars: don't export threadvar unless marked

* tests/dll/visibility: also check for exports

This ensure that these changes don't break manual exports.

* compiler/cgen: hide all variables created for constants

* compiler/ccgtypes: don't export RTTI variables

* compiler/ccgexprs: make all complex const static

* nimbase.h: fix export for windows

* compiler/cgen, ccgthreadvars: export variables correctly

For C/C++ variables, `extern` means that the variable is defined in an
another unit. Added a new N_LIB_EXPORT_VAR to correctly export
variables.

Removed lib/system/allocators.nim. seqs_v2 and strs_v2 now uses allocShared0. (#13190)

* Cleanup, remove lib/system/allocators.nim. seqs_v2 and strs_v2 now use
allocShared0 by default.

* Fixed -d:useMalloc allocShared / reallocShared / deallocShared. These now use the alloc/dealloc/realloc implementation that also takes care of zeroing memory at realloc.

* Removed debug printfs

* Removed unpairedEnvAllocs() from tests/destructor/tnewruntime_misc

* More mmdisp cleanups. The shared allocators do not need to zero memory or throw since the regular ones already do that

* Introduced realloc0 and reallocShared0, these procs are now used by
strs_v2 and seqs_v2. This also allowed the -d:useMalloc allocator to
drop the extra header with allocation length.

* Moved strs_v2/seqs_v2 'allocated' flag into 'cap' field

* Added 'getAllocStats()' to get low level alloc/dealloc counters. Enable with -d:allocStats

* *allocShared implementations for boehm and go allocators now depend on the proper *allocImpl procs

Fix typo for literal `[` (#13243)

The literal value for the `tkBracketLe` token was incorrectly set to `]` rather than `[`. I've had a quick glance at the code and it doesn't look like this change will affect anything at all, but I haven't tested yet - let's see if the CI explodes...

testament/azure: major rewrite (#13246)

This commit features a major rewrite of Azure Pipelines integration,
turning the spaghetti it originally was into something maintainable.

Key changes:
- No longer requires a ton of hooks into testament.
- Results are now cached then bulk-uploaded to prevent throttling from
  Azure Pipelines, avoiding costly timeouts.
- A low timeout is also employed to avoid inflated test time.
- The integration is now documented.

generic stack trace overriding mechanism (nim-lang#12922)

* libbacktrace support

* switch to a generic stack trace overriding mechanism

When "nimStackTraceOverride" is defined, once of the imported modules
can register its own procedure to replace the default stack trace
generation by calling `registerStackTraceOverride(myOwnProc)`.

Tested with `./koch boot -d:release --debugger:native -d:nimStackTraceOverride --import:libbacktrace`
for the compiler itself and `./bin/nim c -r -f --stacktrace:off --debugger:native -d:nimStackTraceOverride --import:libbacktrace foo.nim`
for an external program.

* make the StackTraceOverrideProc {.noinline.}

c_fflush() the rawWrite() buffer (nim-lang#12987)

Stack traces on an unbuffered stderr get out of sync with line-buffered
stdout - usually on Windows terminals or CI logs. This fixes it by
calling C's fflush() on the output buffer in the procedure used for
printing stack traces.

fixes disruptek/nimph#102 multi-level nim.cfg use (nim-lang#13001) [backport]

--exception:goto switch for deterministic exception handling (nim-lang#12977)

This implements "deterministic" exception handling for Nim based on goto instead of setjmp. This means raising an exception is much cheaper than in C++'s table based implementations. Supports hard realtime systems. Default for --gc:arc and the C target because it's generally a good idea and arc is all about deterministic behavior.

Note: This implies that fatal runtime traps are not catchable anymore! This needs to be documented.

added note to re constructor regarding performance (nim-lang#13224)

Since I was new to regex I did not know that there is a compilation going on with ``re"[abc]"`` constructor and so I followed the other examples in the docs blindly, that is I just put the constructor directly in the arguments of match, find, etc., which was inside a loop and then wondered why my performance was so bad. Of course putting it outside the loop made it vastly more performant. People like me would benefit from the small note I added I would think :)

Unexport even more symbols (nim-lang#13214)

* system/gc: don't export markStackAndRegisters

* compiler/cgen: unexport internal symbols

As these functions are Nim-specific walkaround against C's optimization
schemes, they don't serve any purpose being exported.

* compiler/cgen: don't export global var unless marked

* compiler/ccgthreadvars: don't export threadvar unless marked

* tests/dll/visibility: also check for exports

This ensure that these changes don't break manual exports.

* compiler/cgen: hide all variables created for constants

* compiler/ccgtypes: don't export RTTI variables

* compiler/ccgexprs: make all complex const static

* nimbase.h: fix export for windows

* compiler/cgen, ccgthreadvars: export variables correctly

For C/C++ variables, `extern` means that the variable is defined in an
another unit. Added a new N_LIB_EXPORT_VAR to correctly export
variables.

Removed lib/system/allocators.nim. seqs_v2 and strs_v2 now uses allocShared0. (nim-lang#13190)

* Fixed -d:useMalloc allocShared / reallocShared / deallocShared. These now use the alloc/dealloc/realloc implementation that also takes care of zeroing memory at realloc.

* Removed debug printfs

* Removed unpairedEnvAllocs() from tests/destructor/tnewruntime_misc

* More mmdisp cleanups. The shared allocators do not need to zero memory or throw since the regular ones already do that

* Introduced realloc0 and reallocShared0, these procs are now used by
strs_v2 and seqs_v2. This also allowed the -d:useMalloc allocator to
drop the extra header with allocation length.

* Moved strs_v2/seqs_v2 'allocated' flag into 'cap' field

* Added 'getAllocStats()' to get low level alloc/dealloc counters. Enable with -d:allocStats

* *allocShared implementations for boehm and go allocators now depend on the proper *allocImpl procs

testament/azure: major rewrite (nim-lang#13246)

This commit features a major rewrite of Azure Pipelines integration,
turning the spaghetti it originally was into something maintainable.

Key changes:
- No longer requires a ton of hooks into testament.
- Results are now cached then bulk-uploaded to prevent throttling from
  Azure Pipelines, avoiding costly timeouts.
- A low timeout is also employed to avoid inflated test time.
- The integration is now documented.

Changelog:
# v1.2.0 - 2020-04-02

## Standard library additions and changes

- Added overloaded `strformat.fmt` macro that use specified characters as
  delimiter instead of '{' and '}'.
- Added new procs in `tables.nim`: `OrderedTable.pop`, `CountTable.del`,
  `CountTable.pop`, `Table.pop`.
- Added `strtabs.clear` overload that reuses the existing mode.
- Added `browsers.osOpen` const alias for the operating system specific *"open"* command.
- Added `sugar.dup` for turning in-place algorithms like `sort` and `shuffle`
  into operations that work on a copy of the data and return the mutated copy,
  like the existing `sorted` does.
- Added `sugar.collect` that does comprehension for seq/set/table collections.
- Added `sugar.capture` for capturing some local loop variables when creating a
  closure. This is an enhanced version of `closureScope`.
- Added `typetraits.tupleLen` to get number of elements of a tuple/type tuple,
  and `typetraits.get` to get the ith element of a type tuple.
- Added `typetraits.genericParams` to return a tuple of generic params from a
  generic instantiation.
- `options` now treats `proc` like other pointer types, meaning `nil` proc variables
  are converted to `None`.
- Added `os.normalizePathEnd` for additional path sanitization.
- Added `times.fromUnixFloat,toUnixFloat`, sub-second resolution versions of
  `fromUnix`,`toUnixFloat`.
- Added `wrapnils` module for chains of field-access and indexing where the LHS
  can be nil. This simplifies code by reducing need for if-else branches around
  intermediate maybe nil values. E.g. `echo ?.n.typ.kind`.
- Added `minIndex`, `maxIndex` and `unzip` to the `sequtils` module.
- Added `os.isRelativeTo` to tell whether a path is relative to another.
- Added `resetOutputFormatters` to `unittest`.
- Added `expectIdent` to the `macros` module.
- Added `os.isValidFilename` that returns `true` if `filename` argument is valid
  for cross-platform use.
- Added `times.isLeapDay`
- `base64` adds URL-Safe Base64, implements RFC-4648 Section-7.
- Added a new module, `std / compilesettings` for querying the compiler about
  diverse configuration settings.
- Added `net.getPeerCertificates` and `asyncnet.getPeerCertificates` for
  retrieving the verified certificate chain of the peer we are connected to
  through an SSL-wrapped `Socket`/`AsyncSocket`.
- Added `browsers.openDefaultBrowser` without URL, implements IETF RFC-6694 Section-3.
- Added `jsconsole.trace`, `jsconsole.table`, `jsconsole.exception` for JavaScript target.
- Added `distinctBase` overload for values: `assert 12.MyInt.distinctBase == 12`
- Added new module `std/stackframes`, in particular `setFrameMsg`, which enables
  custom runtime annotation of stackframes, see #13351 for examples.
  Turn on/off via `--stackTraceMsgs:on/off`.
- Added `sequtils.countIt`, allowing for counting items using a predicate.
- Added a `with` macro for easy function chaining that's available everywhere,
  there is no need to concern your APIs with returning the first argument
  to enable "chaining", instead use the dedicated macro `with` that
  was designed for it. For example:

```nim
type
  Foo = object
    col, pos: string

proc setColor(f: var Foo; r, g, b: int) = f.col = $(r, g, b)
proc setPosition(f: var Foo; x, y: float) = f.pos = $(x, y)

var f: Foo
with(f, setColor(2, 3, 4), setPosition(0.0, 1.0))
echo f
```

- `macros.newLit` now works for ref object types.
- `macro pragmas` can now be used in type sections.
- 5 new pragmas were added to Nim in order to make the upcoming tooling more
  convenient to use. Nim compiler checks these pragmas for syntax but otherwise
  ignores them. The pragmas are `requires`, `ensures`, `assume`, `assert`, `invariant`.
- `system.writeFile` has been overloaded to also support `openarray[byte]`.
- `asyncdispatch.drain` now properly takes into account `selector.hasPendingOperations`
  and only returns once all pending async operations are guaranteed to have completed.
- `sequtils.zip` now returns a sequence of anonymous tuples i.e. those tuples
  now do not have fields named "a" and "b".
- `distinctBase` has been moved from `sugar` to `typetraits` and now it is
  implemented as compiler type trait instead of macro. `distinctBase` in sugar
  module is now deprecated.
- `CountTable.mget` has been removed from `tables.nim`. It didn't work, and it
  was an oversight to be included in v1.0.
- `tables.merge(CountTable, CountTable): CountTable` has been removed.
  It didn't work well together with the existing inplace version of the same proc
  (`tables.merge(var CountTable, CountTable)`).
  It was an oversight to be included in v1.0.
- `asyncdispatch.drain` now consistently uses the passed timeout value for all
  iterations of the event loop, and not just the first iteration.
  This is more consistent with the other asyncdispatch APIs, and allows
  `asyncdispatch.drain` to be more efficient.
- `base64.encode` and `base64.decode` were made faster by about 50%.
- `htmlgen` adds [MathML](https://wikipedia.org/wiki/MathML) support
  (ISO 40314).
- `macros.eqIdent` is now invariant to export markers and backtick quotes.
- `htmlgen.html` allows `lang` in the `<html>` tag and common valid attributes.
- `macros.basename` and `basename=` got support for `PragmaExpr`,
  so that an expression like `MyEnum {.pure.}` is handled correctly.
- `httpclient.maxredirects` changed from `int` to `Natural`, because negative values
  serve no purpose whatsoever.
- `httpclient.newHttpClient` and `httpclient.newAsyncHttpClient` added `headers`
  argument to set initial HTTP Headers, instead of a hardcoded empty `newHttpHeader()`.
- `parseutils.parseUntil` has now a different behaviour if the `until` parameter is
  empty. This was required for intuitive behaviour of the strscans module
  (see bug #13605).
- `strutils.formatFloat` with `precision = 0` has the same behavior in all
  backends, and it is compatible with Python's behavior,
  e.g. `formatFloat(3.14159, precision = 0)` is now `3`, not `3.`.
- `times.parse` now only uses input to compute its result, and not `now`:
  `parse("2020", "YYYY", utc())` is now `2020-01-01T00:00:00Z` instead of
  `2020-03-02T00:00:00Z` if run on 03-02; it also doesn't crash anymore when
  used on 29th, 30th, 31st of each month.
- `httpcore.==(string, HttpCode)` is now deprecated due to lack of practical
  usage. The `$` operator can be used to obtain the string form of `HttpCode`
  for comparison if desired.
- `std/oswalkdir` was buggy, it's now deprecated and reuses `std/os` procs.
- `net.newContext` now performs SSL Certificate checking on Linux and OSX.
  Define `nimDisableCertificateValidation` to disable it globally.
- `os.walkDir` and `os.walkDirRec` now have new flag, `checkDir` (default: false).
  If it is set to true, it will throw if input dir is invalid instead of a noop
  (which is the default behaviour, as it was before this change),
  `os.walkDirRec` only throws if top-level dir is invalid, but ignores errors for
  subdirs, otherwise it would be impossible to resume iteration.
- The `FD` variant of `selector.unregister` for `ioselector_epoll` and
  `ioselector_select` now properly handle the `Event.User` select event type.
- `joinPath` path normalization when `/` is the first argument works correctly:
  `assert "/" / "/a" == "/a"`. Fixed the edge case: `assert "" / "" == ""`.
- `xmltree` now adds indentation consistently to child nodes for any number
  of children nodes.
- `os.splitPath()` behavior synchronized with `os.splitFile()` to return "/"
  as the dir component of `/root_sub_dir` instead of the empty string.
- The deprecated `lc` macro has been removed from `sugar`. It is now replaced with the
  more powerful `collect` macro.
- `os.relativePath("foo", "foo")` is now `"."`, not `""`, as `""` means invalid
  path and shouldn't be conflated with `"."`; use `-d:nimOldRelativePathBehavior`
  to restore the old behavior.
- `os.joinPath(a, b)` now honors trailing slashes in `b` (or `a` if `b` = "").
- `base64.encode` no longer supports `lineLen` and `newLine`.
  Use `base64.encodeMime` instead.


## Language changes

- An `align` pragma can now be used for variables and object fields, similar
  to the `alignas` declaration modifier in C/C++.
- `=sink` type bound operator is now optional. Compiler can now use combination
  of `=destroy` and `copyMem` to move objects efficiently.
- Unsigned integer operators have been fixed to allow promotion of the first operand.
- Conversions to unsigned integers are unchecked at runtime, imitating earlier Nim
  versions. The documentation was improved to acknowledge this special case.
  See nim-lang/RFCs#175 for more details.
- New syntax for lvalue references: `var b {.byaddr.} = expr` enabled by
  `import std/decls`.
- `var a {.foo.}: MyType = expr` now lowers to `foo(a, MyType, expr)` for
  non-builtin pragmas, enabling things like lvalue references (see `decls.byaddr`).


## Compiler changes

- Generated JS code uses spaces, instead of mixed spaces and tabs.
- The Nim compiler now supports the ``--asm`` command option for easier
  inspection of the produced assembler code.
- The Nim compiler now supports a new pragma called ``.localPassc`` to
  pass specific compiler options to the C(++) backend for the C(++) file
  that was produced from the current Nim module.
- The compiler now inferes "sink parameters". To disable this for a specific routine,
  annotate it with `.nosinks`. To disable it for a section of code, use
  `{.push sinkInference: off.}`...`{.pop.}`.
- The compiler now supports a new switch `--panics:on` that turns runtime
  errors like `IndexError` or `OverflowError` into fatal errors that **cannot**
  be caught via Nim's `try` statement. `--panics:on` can improve the
  runtime efficiency and code size of your program significantly.
- The compiler now warns about inheriting directly from `system.Exception` as
  this is **very bad** style. You should inherit from `ValueError`, `IOError`,
  `OSError` or from a different specific exception type that inherits from
  `CatchableError` and cannot be confused with a `Defect`.
- The error reporting for Nim's effect system has been improved.
- Implicit conversions for `const` behave correctly now, meaning that code like
  `const SOMECONST = 0.int; procThatTakesInt32(SOMECONST)` will be illegal now.
  Simply write `const SOMECONST = 0` instead.
- The `{.dynlib.}` pragma is now required for exporting symbols when making
  shared objects on POSIX and macOS, which make it consistent with the behavior
  on Windows.
- The compiler is now more strict about type conversions concerning proc
  types: Type conversions cannot be used to hide `.raise` effects or side
  effects, instead a `cast` must be used. With the flag `--useVersion:1.0` the
  old behaviour is emulated.
- The Nim compiler now implements a faster way to detect overflows based
  on GCC's `__builtin_sadd_overflow` family of functions. (Clang also
  supports these). Some versions of GCC lack this feature and unfortunately
  we cannot detect this case reliably. So if you get compilation errors like
  "undefined reference to `__builtin_saddll_overflow`" compile your programs
  with `-d:nimEmulateOverflowChecks`.


## Tool changes

- Nimpretty doesn't accept negative indentation argument anymore, because it was
  breaking files.

netbsd-srcmastr pushed a commit to NetBSD/pkgsrc that referenced this issue Apr 6, 2020
Changelog:
# v1.2.0 - 2020-04-02

## Standard library additions and changes

- Added overloaded `strformat.fmt` macro that use specified characters as
  delimiter instead of '{' and '}'.
- Added new procs in `tables.nim`: `OrderedTable.pop`, `CountTable.del`,
  `CountTable.pop`, `Table.pop`.
- Added `strtabs.clear` overload that reuses the existing mode.
- Added `browsers.osOpen` const alias for the operating system specific *"open"* command.
- Added `sugar.dup` for turning in-place algorithms like `sort` and `shuffle`
  into operations that work on a copy of the data and return the mutated copy,
  like the existing `sorted` does.
- Added `sugar.collect` that does comprehension for seq/set/table collections.
- Added `sugar.capture` for capturing some local loop variables when creating a
  closure. This is an enhanced version of `closureScope`.
- Added `typetraits.tupleLen` to get number of elements of a tuple/type tuple,
  and `typetraits.get` to get the ith element of a type tuple.
- Added `typetraits.genericParams` to return a tuple of generic params from a
  generic instantiation.
- `options` now treats `proc` like other pointer types, meaning `nil` proc variables
  are converted to `None`.
- Added `os.normalizePathEnd` for additional path sanitization.
- Added `times.fromUnixFloat,toUnixFloat`, sub-second resolution versions of
  `fromUnix`,`toUnixFloat`.
- Added `wrapnils` module for chains of field-access and indexing where the LHS
  can be nil. This simplifies code by reducing need for if-else branches around
  intermediate maybe nil values. E.g. `echo ?.n.typ.kind`.
- Added `minIndex`, `maxIndex` and `unzip` to the `sequtils` module.
- Added `os.isRelativeTo` to tell whether a path is relative to another.
- Added `resetOutputFormatters` to `unittest`.
- Added `expectIdent` to the `macros` module.
- Added `os.isValidFilename` that returns `true` if `filename` argument is valid
  for cross-platform use.
- Added `times.isLeapDay`
- `base64` adds URL-Safe Base64, implements RFC-4648 Section-7.
- Added a new module, `std / compilesettings` for querying the compiler about
  diverse configuration settings.
- Added `net.getPeerCertificates` and `asyncnet.getPeerCertificates` for
  retrieving the verified certificate chain of the peer we are connected to
  through an SSL-wrapped `Socket`/`AsyncSocket`.
- Added `browsers.openDefaultBrowser` without URL, implements IETF RFC-6694 Section-3.
- Added `jsconsole.trace`, `jsconsole.table`, `jsconsole.exception` for JavaScript target.
- Added `distinctBase` overload for values: `assert 12.MyInt.distinctBase == 12`
- Added new module `std/stackframes`, in particular `setFrameMsg`, which enables
  custom runtime annotation of stackframes, see #13351 for examples.
  Turn on/off via `--stackTraceMsgs:on/off`.
- Added `sequtils.countIt`, allowing for counting items using a predicate.
- Added a `with` macro for easy function chaining that's available everywhere,
  there is no need to concern your APIs with returning the first argument
  to enable "chaining", instead use the dedicated macro `with` that
  was designed for it. For example:

```nim
type
  Foo = object
    col, pos: string

proc setColor(f: var Foo; r, g, b: int) = f.col = $(r, g, b)
proc setPosition(f: var Foo; x, y: float) = f.pos = $(x, y)

var f: Foo
with(f, setColor(2, 3, 4), setPosition(0.0, 1.0))
echo f
```

- `macros.newLit` now works for ref object types.
- `macro pragmas` can now be used in type sections.
- 5 new pragmas were added to Nim in order to make the upcoming tooling more
  convenient to use. Nim compiler checks these pragmas for syntax but otherwise
  ignores them. The pragmas are `requires`, `ensures`, `assume`, `assert`, `invariant`.
- `system.writeFile` has been overloaded to also support `openarray[byte]`.
- `asyncdispatch.drain` now properly takes into account `selector.hasPendingOperations`
  and only returns once all pending async operations are guaranteed to have completed.
- `sequtils.zip` now returns a sequence of anonymous tuples i.e. those tuples
  now do not have fields named "a" and "b".
- `distinctBase` has been moved from `sugar` to `typetraits` and now it is
  implemented as compiler type trait instead of macro. `distinctBase` in sugar
  module is now deprecated.
- `CountTable.mget` has been removed from `tables.nim`. It didn't work, and it
  was an oversight to be included in v1.0.
- `tables.merge(CountTable, CountTable): CountTable` has been removed.
  It didn't work well together with the existing inplace version of the same proc
  (`tables.merge(var CountTable, CountTable)`).
  It was an oversight to be included in v1.0.
- `asyncdispatch.drain` now consistently uses the passed timeout value for all
  iterations of the event loop, and not just the first iteration.
  This is more consistent with the other asyncdispatch APIs, and allows
  `asyncdispatch.drain` to be more efficient.
- `base64.encode` and `base64.decode` were made faster by about 50%.
- `htmlgen` adds [MathML](https://wikipedia.org/wiki/MathML) support
  (ISO 40314).
- `macros.eqIdent` is now invariant to export markers and backtick quotes.
- `htmlgen.html` allows `lang` in the `<html>` tag and common valid attributes.
- `macros.basename` and `basename=` got support for `PragmaExpr`,
  so that an expression like `MyEnum {.pure.}` is handled correctly.
- `httpclient.maxredirects` changed from `int` to `Natural`, because negative values
  serve no purpose whatsoever.
- `httpclient.newHttpClient` and `httpclient.newAsyncHttpClient` added `headers`
  argument to set initial HTTP Headers, instead of a hardcoded empty `newHttpHeader()`.
- `parseutils.parseUntil` has now a different behaviour if the `until` parameter is
  empty. This was required for intuitive behaviour of the strscans module
  (see bug #13605).
- `strutils.formatFloat` with `precision = 0` has the same behavior in all
  backends, and it is compatible with Python's behavior,
  e.g. `formatFloat(3.14159, precision = 0)` is now `3`, not `3.`.
- `times.parse` now only uses input to compute its result, and not `now`:
  `parse("2020", "YYYY", utc())` is now `2020-01-01T00:00:00Z` instead of
  `2020-03-02T00:00:00Z` if run on 03-02; it also doesn't crash anymore when
  used on 29th, 30th, 31st of each month.
- `httpcore.==(string, HttpCode)` is now deprecated due to lack of practical
  usage. The `$` operator can be used to obtain the string form of `HttpCode`
  for comparison if desired.
- `std/oswalkdir` was buggy, it's now deprecated and reuses `std/os` procs.
- `net.newContext` now performs SSL Certificate checking on Linux and OSX.
  Define `nimDisableCertificateValidation` to disable it globally.
- `os.walkDir` and `os.walkDirRec` now have new flag, `checkDir` (default: false).
  If it is set to true, it will throw if input dir is invalid instead of a noop
  (which is the default behaviour, as it was before this change),
  `os.walkDirRec` only throws if top-level dir is invalid, but ignores errors for
  subdirs, otherwise it would be impossible to resume iteration.
- The `FD` variant of `selector.unregister` for `ioselector_epoll` and
  `ioselector_select` now properly handle the `Event.User` select event type.
- `joinPath` path normalization when `/` is the first argument works correctly:
  `assert "/" / "/a" == "/a"`. Fixed the edge case: `assert "" / "" == ""`.
- `xmltree` now adds indentation consistently to child nodes for any number
  of children nodes.
- `os.splitPath()` behavior synchronized with `os.splitFile()` to return "/"
  as the dir component of `/root_sub_dir` instead of the empty string.
- The deprecated `lc` macro has been removed from `sugar`. It is now replaced with the
  more powerful `collect` macro.
- `os.relativePath("foo", "foo")` is now `"."`, not `""`, as `""` means invalid
  path and shouldn't be conflated with `"."`; use `-d:nimOldRelativePathBehavior`
  to restore the old behavior.
- `os.joinPath(a, b)` now honors trailing slashes in `b` (or `a` if `b` = "").
- `base64.encode` no longer supports `lineLen` and `newLine`.
  Use `base64.encodeMime` instead.


## Language changes

- An `align` pragma can now be used for variables and object fields, similar
  to the `alignas` declaration modifier in C/C++.
- `=sink` type bound operator is now optional. Compiler can now use combination
  of `=destroy` and `copyMem` to move objects efficiently.
- Unsigned integer operators have been fixed to allow promotion of the first operand.
- Conversions to unsigned integers are unchecked at runtime, imitating earlier Nim
  versions. The documentation was improved to acknowledge this special case.
  See nim-lang/RFCs#175 for more details.
- New syntax for lvalue references: `var b {.byaddr.} = expr` enabled by
  `import std/decls`.
- `var a {.foo.}: MyType = expr` now lowers to `foo(a, MyType, expr)` for
  non-builtin pragmas, enabling things like lvalue references (see `decls.byaddr`).


## Compiler changes

- Generated JS code uses spaces, instead of mixed spaces and tabs.
- The Nim compiler now supports the ``--asm`` command option for easier
  inspection of the produced assembler code.
- The Nim compiler now supports a new pragma called ``.localPassc`` to
  pass specific compiler options to the C(++) backend for the C(++) file
  that was produced from the current Nim module.
- The compiler now inferes "sink parameters". To disable this for a specific routine,
  annotate it with `.nosinks`. To disable it for a section of code, use
  `{.push sinkInference: off.}`...`{.pop.}`.
- The compiler now supports a new switch `--panics:on` that turns runtime
  errors like `IndexError` or `OverflowError` into fatal errors that **cannot**
  be caught via Nim's `try` statement. `--panics:on` can improve the
  runtime efficiency and code size of your program significantly.
- The compiler now warns about inheriting directly from `system.Exception` as
  this is **very bad** style. You should inherit from `ValueError`, `IOError`,
  `OSError` or from a different specific exception type that inherits from
  `CatchableError` and cannot be confused with a `Defect`.
- The error reporting for Nim's effect system has been improved.
- Implicit conversions for `const` behave correctly now, meaning that code like
  `const SOMECONST = 0.int; procThatTakesInt32(SOMECONST)` will be illegal now.
  Simply write `const SOMECONST = 0` instead.
- The `{.dynlib.}` pragma is now required for exporting symbols when making
  shared objects on POSIX and macOS, which make it consistent with the behavior
  on Windows.
- The compiler is now more strict about type conversions concerning proc
  types: Type conversions cannot be used to hide `.raise` effects or side
  effects, instead a `cast` must be used. With the flag `--useVersion:1.0` the
  old behaviour is emulated.
- The Nim compiler now implements a faster way to detect overflows based
  on GCC's `__builtin_sadd_overflow` family of functions. (Clang also
  supports these). Some versions of GCC lack this feature and unfortunately
  we cannot detect this case reliably. So if you get compilation errors like
  "undefined reference to `__builtin_saddll_overflow`" compile your programs
  with `-d:nimEmulateOverflowChecks`.


## Tool changes

- Nimpretty doesn't accept negative indentation argument anymore, because it was
  breaking files.
