9.0.0
# Major Features
## 64-bit capacity: Data values larger than 2 GB
- Strings can be any length (that fits in your available memory)
- Lists and dictionaries can have very large numbers of elements
## Internationalization of text
- Full Unicode range of codepoints
- New encodings: `utf-16`/`utf-32`/`ucs-2`(`le`|`be`), `CESU-8`, etc.
- `encoding` options `-profile`, `-failindex` manage encoding of I/O.
- `msgcat` supports custom locale search list
- `source` defaults to `-encoding utf-8`
## Zip filesystems and attached archives
- Packaging of the Tcl script library with the Tcl binary library,
meaning that the `TCL_LIBRARY` environment variable is usually not
required.
- Packaging of an application into a virtual filesystem is now a
supported
core Tcl feature.
## Unix notifiers available using `epoll()` or `kqueue()`
- This relieves limits on file descriptors imposed by legacy
`select()` and fixes a performance bottleneck.
# Incompatibilities
## Notable incompatibilities
- Unqualified varnames resolved in current namespace, not global.
Note that in almost all cases where this causes a change, the
change is actually the removal of a latent bug.
- No `--disable-threads` build option. Always thread-enabled.
- I/O malencoding default response: raise error (`-profile strict`)
- Windows platform needs Windows 7 or Windows Server 2008 R2 or later
- Ended interpretation of `~` as home directory in pathnames.
(See `file home` and `file tildeexpand` for replacements when you
need them.)
- Removed the `identity` encoding.
(There were only ever very few valid use cases for this; almost
all uses were systematically wrong.)
- Removed the encoding alias `binary` to `iso8859-1`.
- `$::tcl_precision` no longer controls string generation of doubles.
(If you need a particular precision, use `format`.)
- Removed pre-Tcl 8 legacies: `case`, `puts` and `read` variant
syntaxes.
- Removed subcommands [`trace variable`|`vdelete`|`vinfo`]
- Removed `-eofchar` option for write channels.
- On Windows 10+ (Version 1903 or higher), system encoding is always
utf-8.
- `%b`/`%d`/`%o`/`%x` format modifiers (without size modifier) for
`format` and `scan` always truncate to 32-bits on all platforms.
- `%L` size modifier for `scan` no longer truncates to 64-bit.
- Removed command `::tcl::unsupported::inject`.
(See `coroinject` and `coroprobe` for supported commands with
significantly more comprehensible semantics.)
## Incompatibilities in C public interface
- Extensions built against Tcl 8.6 and before will not work with
Tcl 9.0;
ABI compatibility was a non-goal for 9.0. In _most_ cases,
rebuilding against Tcl 9.0 should work except when a removed API
function is used.
- Many arguments expanded type from `int` to `Tcl_Size`, a signed
integer type large enough to support 64-bit sized memory objects.
The constant `TCL_AUTO_LENGTH` is a value of that type that
indicates that the length should be obtained using an appropriate
function (typically `strlen()` for `char *` values).
- Ended support for `Tcl_ChannelTypeVersion` less than 5
- Introduced versioning of the `Tcl_ObjType` struct
- Removed macros `CONST*`: Tcl 9 support means dropping Tcl 8.3
support.
(Replaced with standard C `const` keyword going forward.)
- Removed registration of several `Tcl_ObjType`s.
- Removed API functions:
- `Tcl_Backslash()`
- `Tcl_*VA()`
- `Tcl_*MathFunc*()`
- `Tcl_MakeSafe()`
- `Tcl_(Save|Restore|Discard|Free)Result()`
- `Tcl_EvalTokens()`
- `Tcl_(Get|Set)DefaultEncodingDir()`
- `Tcl_UniCharN(case)cmp()`
- `Tcl_UniCharCaseMatch()`
- Revised many internals; beware reliance on undocumented behaviors.
# New Features
## New commands
- `array default` — Specify default values for arrays (note that
this alters the behaviour of `append`, `incr`, `lappend`).

binary data.
- `coroinject`, `coroprobe` — Interact with paused coroutines.
- `clock add weekdays` — Clock arithmetic with week days.
- `const`, `info const*` — Commands for defining constants (variables
that can't be modified).
- `dict getwithdefault` — Define a fallback value to use when
`dict get` would otherwise fail.
- `file home` — Get the user home directory.
- `file tempdir` — Create a temporary directory.
- `file tildeexpand` — Expand a file path containing a `~`.
- `info commandtype` — Introspection for the kinds of commands.
- `ledit` — Equivalent to `lreplace` but on a list in a variable.
- `lpop` — Remove an item from a list in a variable.
- `lremove` — Remove a sublist from a list in a variable.
- `lseq` — Generate a list of numbers in a sequence.
- `package files` — Describe the contents of a package.
- `string insert` — Insert a string as a substring of another string.
- `string is dict` — Test whether a string is a dictionary.
- `tcl::process` — Commands for working with subprocesses.
- `*::build-info` — Obtain information about the build of Tcl.
- `readFile`, `writeFile`, `foreachLine` — Simple procedures for
basic working with files.

input and reading passwords.

## Numbers
- <code>0<i>NNN</i></code> format is no longer octal interpretation.
Use <code>0o<i>NNN</i></code>.
- <code>0d<i>NNNN</i></code> format to compel decimal interpretation.
- <code>NN_NNN_NNN</code>, underscores in numbers for optional
readability
- Functions: `isinf()`, `isnan()`, `isnormal()`, `issubnormal()`,
`isunordered()`
- Command: `fpclassify`
- Function `int()` no longer truncates to word size
## TclOO facilities
