Emacs 29.3 is an emergency bugfix release intended to fix several
security vulnerabilities described below.
* Editing Changes in Emacs 29.3
** Arbitrary Lisp code is no longer evaluated as part of turning on Org mode.
This is for security reasons, to avoid evaluating malicious Lisp code.
* Changes in Specialized Modes and Packages in Emacs 29.3
** New buffer-local variable 'untrusted-content'.
When this is non-nil, Lisp programs should treat buffer contents with
extra caution.
* New Modes and Packages in Emacs 29.3
** Gnus now treats inline MIME contents as untrusted.
To get back previous insecure behavior, 'untrusted-content' should be
reset to nil in the buffer.

** LaTeX preview is now by default disabled for email attachments.
To get back previous insecure behavior, set the variable
'org--latex-preview-when-risky' to a non-nil value.

* Changes in Emacs 29.3 on Non-Free Operating Systems
