The "Minimal release" of Squeak would be the smallest possible kernel which contains a bootstrappable core of Squeak. This could be used for creating lightweight configurations, experiments, etc. For 3.6 there exists a minimal release done by Boris Gaertner.
Those interested in tiny Squeak images would perhaps like to check out Craig Latta's work at http://www.netjam.org/squat. This is a tiny version of squeak, which could potentially become the official Minimal image.

Found on the Squeak mailing list by Pavel Krivanek:
Hi all,
I have prepared an experimental kernel image based on Squeak 3.7.
Properties:
size: 1.3 MB
no Morphic
no MVC
no Sound
no Network
no Browser, Debugger etc.
no SUnit
no Projects support (there’s only one default project)
only necessary processes
no ObsoleteClasses (consistent references in sources)
single font
simple console with clipboard support
transcript output (with file log)
transparent creation mechanism
Download:
image with changes: ftp://comtalk.eu/pub/bootstrap/kernel.zip
please, can somebody place it to a new location with better connectivity?
How to prepare it:
use QuiteSmall image (http://www.swerlingphoto.com/squeak/QuiteSmall-3.7.zip)
load Mirrors.1.cs
load Bootstrap.st
evaluate "Bootstrap start"
in console type "Bootstrap revert"
wait a while
condense changes, clear transcript, save image
How it works:
for all classes in system "mirrors" are created. Mirrors are classes with prefix "Xxx" that contain only class definition and methods. They contain no valid references to class variables.
mirrors are modified so they contain whole class hierarchy for new system. There are original classes used in code of methods.
initial cleanup is executed and system processes are recreated
for all original classes, methods of mirrors are assigned. Methods that aren’t in mirrors are removed. Then the new definition of class is used.
unnecessary original classes are removed
mirrors are removed
whole sources are recompiled
additional cleanup is executed
The console is very simple. Now it cannot simulate FillInTheBlank, confirmations, user interrupt etc.
