-# Tcl/Tk 9.0b2 Release Announcement
-April ??, 2024
 
-The Tcl Core Team is pleased to announce the 9.0b2 releases of the Tcl
-dynamic language and the Tk graphical interface package.  These are the
-second beta releases of Tcl 9.0 and Tk 9.0.  More details can be found below.
+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`

-## <a id="wheretoget">1.</a> Where to get the new releases
-
-Tcl/Tk 9.0b2 sources are freely available as open source from the Tcl
-SourceForge project's file distribution area:
-
-        https://sourceforge.net/projects/tcl/files/
-
-This distribution is source code only.  We keep links to some third
-parties offering pre-built binaries for various systems here:
-
-        https://www.tcl-lang.org/software/tcltk/bindist.html
-
-## <a id="summary">2.</a> 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.

-## <a id="tips">4.</a> Tcl Improvement Proposals (TIPs)
-
-Each new user-visible feature in Tcl or Tk should find its origins in
-a Tcl Improvement Proposal (TIP).  TIPs are published, edited, considered
-and voted in public, and should contain valuable information about how
-a feature came to be the way it is.  See the full collection here:
-
-    https://tip.tcl-lang.org/
-
-## <a id="support">5.</a> Additional support resources

-See the following links for an accumulation of migration advice:

-https://core.tcl-lang.org/tcl/wiki?name=Migrating+scripts+to+Tcl+9
-
-There has been much progress already porting many known applications,
-extensions, and packages in the Tcl world to compatibility with Tcl/Tk 9:
