Two remarks:
A. Build problem
================
I use to building for a x86_64-mingw32 target from a linux host, using a gcc cross compiler. This
went well for Tcl. For Tk, the build aborted with:

B. Typo
=======
In the announcement text below, referring to a 9.0b1 release, when actually announcing a 9.0b2
release. Marked by me with "typo".

> Tcl/Tk 9.0b1 sources are freely available as open source from the Tcl <===== typo

> General Summary
> ---------------
>
> These are new major versions of both Tcl and Tk. There are new features
> to be enjoyed. There are incompatibilities to be considered. The list
> of both is long and detailed and not fully included here. We believe many
> scripts written for Tcl 8 will run unchanged in Tcl 9. We believe many more
> can be modified in small and simple ways to produce a new script that runs
> in both Tcl 8 and Tcl 9. We expect that extensions and applications using
> the public C APIs of Tcl and Tk will involve more effort, but that it is
> still within reasonable reach to produce source code supporting both Tcl 8
> and Tcl 9 while both releases remain in widespread use.
>
> These are beta releases. The developers believe the new feature set is
> complete enough and the code quality is high enough that it is time for
> a larger audience of Tcl/Tk users to give them a try and report back
> to the developers what difficulties need resolution before stable
> releases of Tcl/Tk 9.0.0.
>
> The experiences of Tcl/Tk 8 users adapting their code to the beta releases
> of Tcl/Tk 9 will shape the final interfaces of Tcl/Tk 9.0.0, and will
> determine the need for possible Tcl/Tk 8.7 releases that might supply
> additional lifecycle and migration support.
>
> It is not recommended to deploy these beta releases directly to mission
> critical use without significant testing and review.

> Tcl Changes Summary
> -------------------
>
> The source code for Tcl is managed by fossil. Tcl developers coordinate all
> changes to the Tcl source code at
>
> > [Tcl Source Code](https://core.tcl-lang.org/tcl/timeline)
>
> Release Tcl 9.0b2 arises from the check-in with tag core-9-0-b2.
>
> Highlighted differences between Tcl 9.0 and Tcl 8.6 are summarized below,
> with focus on changes important to programmers using the Tcl library and
> writing Tcl scripts.
>
> ## 64-bit capacity: Data values larger than 2Gb
>
> ## 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.
>
> ## Unix notifiers available using epoll() or kqueue()
> - relieves limits on file descriptors imposed by legacy select()
>
> ## Notable incompatibilities
> - Unqualified varnames resolved in current namespace, not global.
> - 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
> - Removed the "identity" encoding
> - $::tcl_precision no longer controls string generation of doubles
> - Removed Tcl 7 legacies: [case], [puts] [read] variant syntaxes
> - Removed subcommands [trace variable|vdelete|vinfo]
> - No -eofchar option for channels anymore for writing.
> - On Windows 10+ (Version 1903 or higher), system encoding is always utf-8.
>
> ## Incompatibilities in C public interface
> - Many arguments expanded type from int to Tcl_Size
> - 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
> - Removed routines:
> > 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()
>
> ## New commands
> - `array default`, `array for`
> - `coroinject`, `coroprobe`
> - `clock add weekdays`
> - `const`, `info const*`
> - `dict getdefault`
> - `file tempdir`, `file home`, `file tildeexpand`
> - `info commandtype`
> - `ledit`
> - `lpop`
> - `lremove`
> - `lseq`
> - `package files`
> - `string insert`, `string is dict`
> - `tcl::process`
> - `*::build-info`
>
> ## New command options
> - `regsub ... -command ...`
> - `lsearch ... -stride ...`
> - `clock scan ... -validate ...`
> - `socket ... -nodelay ... -keepalive ...`
> - `vwait` controlled by several new options
>
> ## Numbers
> - 0NNN format is no longer octal interpretation. Use 0oNNN.
> - 0dNNNN format to compel decimal interpretation.
> - NN_NNN_NNN, underscores in numbers for optional readability
> - Functions: isinf() isnan() isnormal() issubnormal() isunordered()
> - `fpclassify`
> - Function int() no longer truncates to word size
>
> ## tcl::oo facilities
> - private variable and methods
> - `method -export`, `method -unexport`
>

>
> ## Many improvements to use of platform features and conventions.
> - Built-in widgets and themes are scaling-aware.
> - Improved support of two-finger gestures, where available
> - The `tk windowingsystem` "aqua" needs macOS 10.10 or later
>

> - `$image get ... -withalpha ...`
> - All indices now accept the forms **end**, **end-int**, **int+|-int**
>
> ## Improved widget appearance
> - `ttk::notebook` with nondefault tab positions
>
> ## Images
> - Partial SVG support
> - Read/write access to photo image metadata
