* lisp/ox-html.el (org-html-latex-image-options,
org-html-prepare-latex-images, org-html-latex-image,
org-html-latex-image--data, org-html-close-tag): Delegate LaTeX
preview image creation to `org-latex-preview-cache-images'.
Require both 'svg and 'svg-embed in the :inline condition of
`org-html-latex-image-options' to embed svg tags. Handle LaTeX
preview image generation errors gracefully when exporting to html,
and highlight missing images in the html output.
* lisp/ox-html.el (org-html-latex-image--data, org-html-latex-image):
Add support for inlining dvisvgm-exported svgs as <svg> elements,
preserving the effect of the currentColor attribute. While making this
change, we improve a few other aspects of the html LaTeX fragment export
system, namely refactoring/code style improvements and the recognition
of \[...\] and $$...$$ fragments as blocks not inline fragments.
* lisp/org-latex-preview.el (org-latex-preview--construct-entries,
org-latex-preview-auto--regenerate-overlay): Blank fragments produce
invisible previews, which is at best silly and at worst confusing. It's
much better to simply not produce a preview image of blank fragments.
We also now avoid exessive re-numbering calculations when repeatadly
generating live previews.
* lisp/ox-html.el (org-html-latex-image, org-html-prepare-latex-images,
org-html-latex-image-options): Allow for customising the LaTex image
directory in `org-html-latex-image-options'.
* lisp/org-latex-preview.el (org-latex-preview-options,
org-latex-preview-appearance-options): Rename
`org-latex-preview-options' to `org-latex-preview-appearance-options',
as it better reflects the purpose of the variable.
(org-latex-preview--tex-styled, org-latex-preview--image-extract-async,
org-latex-preview--create-tex-file,
org-latex-preview--create-image-async, org-latex-preview--hash,
org-latex-preview-place, org-latex-preview--update-overlay): Put the
page width specification in `org-latex-preview-appearance-options', and
adjust existing code to handle this new structuring.
* lisp/ox-html.el (org-html-prepare-latex-images,
org-html-latex-image-options): Adjust for the
`org-latex-preview-appearance-options' rename, and put :page-width in
the options plist, just with a raised value of 1.0 as the HTML default.
* lisp/org.el (org-do-latex-and-related, org-latex-preview-options),
org-compute-latex-and-related-regexp): Adjust for the
`org-latex-preview-appearance-options' rename.
* lisp/org-compat.el: Adjust for the
`org-latex-preview-appearance-options' rename.
* lisp/ob-latex.el (org-babel-execute:latex, org-latex-preview-header)):
Adjust for the `org-latex-preview-appearance-options' rename.
* etc/ORG-NEWS: Adjust for the `org-latex-preview-appearance-options'
rename.
* doc/org-manual.org (Previewing LaTeX fragments): Adjust for the
`org-latex-preview-appearance-options' rename.
* lisp/ox-html.el (org-html-latex-image, org-html-latex-image-options):
Add a new `org-html-latex-image-options' keyword, ":inline", which
controls image inlining in `org-html-latex-image'.
* lisp/org-latex-preview.el (org-latex-preview--create-tex-file,
org-latex-preview--hash, org-latex-preview-place,
org-latex-preview-clear-cache): The only the default preamble was being
hashed, which led to incorrect results across documents. To correctly
hash the preamble, it is now determined at the start of
`org-latex-preview-place', and used in `org-latex-preview--hash',
`org-latex-preview--create-tex-file', and
`org-latex-preview-clear-cache'.
* lisp/ox-html.el (org-html-latex-environment, org-html-format-latex,
org-latex-to-html-convert-command, org-format-latex-as-html,
org-html-latex-image-options): Introduce new functions and variables to
work directly with the new org-latex-preview and ox-mathml API.
* lisp/org-latex-preview.el (org-format-latex-as-html,
org-latex-preview--tex-styled, org-latex-preview-replace-fragments,
org-latex-to-html-convert-command, org-latex-preview-options,
org-latex-preview-place-image-link): Move all of the HTML-specific
processing out of org-latex-preview.el, and into ox-html.el, and remove
now-obsolete code.
* lisp/org-compat.el (org-place-formula-image, org-html-format-latex):
Relocate a copy of `org-place-formula-image' and `org-html-format-latex'
here, and mark them as obsolete.
* lisp/org-latex-preview.el (org-format-latex, org-create-latex-preview,
org-latex-replace-fragments): The rather large `org-format-latex'
function mixed the preview and export code paths together in rather
confusing way. This has now been split into
`org-latex-replace-fragments' for export, and
`org-latex-preview-fragments' for in-buffer previews.
(org--latex-preview-region): Replace `org-format-latex' with the more
specific `org-latex-preview-fragments'.
(org-latex-tentative-math-re): Instead of let-binding the math regexp,
use a const and explain its usage.
* lisp/ox-odt.el (org-odt--translate-latex-fragments): Replace
`org-format-latex' with the more specific `org-latex-replace-fragments`.
* lisp/ox-html.el (org-html-format-latex): Replace `org-format-latex'
with the more specific `org-latex-replace-fragments`.
* lisp/ox-html.el (org-html-toc): When multiple TOCs are generated
inside the exported document, make sure that they do not have
duplicate IDs.

faces without :inherit property to the generated css. Update the
docstring, detailing that the css class names are the face names with
`org-html-htmlize-font-prefix' prepended.
* lisp/ox-html.el (org-html-inline-image-rules): Add AVIF image
support for inline images on HTML export.
AVIF is well supported by browsers these days and offers similar
features and much better compression than the other image formats
commonly used for the web.

TINYCHANGE
lisp/ox-ascii.el: Create alias `org-export-region-to-ascii` for

lisp/ox-texinfo.el: Create alias `org-export-region-to-texinfo` for

doc/org-manual.org: Change commands from "*-convert-region-*" form to
the "org-export-region-to-*" aliases. Add function index for aliases.
* doc/org-manual.org (Exporting): Add cindex entry for both "backend"
and "back-end" for better searchability.
All other changes are trivial.
Note that `org-element-export-snippet-parser' will still use :back-end
property. So will ox.el in INFO channel.
* lisp/ox-html.el (org-html--id-attr-prefix):
* lisp/ox-odt.el (org-odt--id-attr-prefix): Refactor hardcoded "ID-"
as a new private variable.
* org/ox-html.el (org-html--reference): Add support for the ID
property (previously only supported CUSTOM_ID).
These changes make crossfile ID links work in the exported HTML when
`org-html-prefer-user-labels' is not-nil.
* lisp/ox-html.el (org-html-src-block): Do not treat src blocks
without LANG as example blocks. Instead, export them using "nil"
language. This way, such src blocks will get captions, unlike example
blocks.
The new behavior is consistent with ox-latex and ox-ascii.

buffer upon finished, when the target is provided. Make sure that
remaining buffer copy does not preserve `buffer-file-name' from the

(org-export-copy-buffer): Allow copying into provided buffer and copy
selectively passing the new optional arguments to
`org-export--generate-copy-script'. Do not try to check if all the
local variable values are `read'able - it is only needed during async
export.
* lisp/ox-html.el (org-html-format-latex): Re-use the same hidden
buffer during export. Only copy local variables into that buffer.
This commit avoids excessive calls to `org-mode' and copying the
exported buffer contents for every single latex fragment. The result
is lower impact on GC and better overall performance.
