This appendix is informative.
Listed in this section are all the changes have been made to this Candidate Recommendation relative to the previous public Working Draft of SVG Tiny 1.2. Cosmetic changes (i.e. correction of typos, changes related to the styling of the document and addition of links) need not be listed.
All examples of SVG 1.2 now use "xml:id" rather than "id".
References to SMIL 2.0 Second Edition updated to SMIL 2.1
Made Namespaces in XML 1.0 allowed everywhere to avoid version 1.1 requiring XML 1.1 for all documents.
Removed all modules from the spec.
Changed all mentions of "XML character data" to "XML content".
'Animation Elements' definition is added to the list of definitions.
'SVG User Agent' definition is added to the list of definitions.
'font', 'linearGradient' and 'radialGradient' elements are added to the rendering tree definition as elements not part of the rendering tree.
Namespace policy documented per [NSState].
The following sentence added to 1.3: "Backwards compatible means that conformant SVG Tiny 1.1 content will render the same in conformant SVG Tiny 1.2 User Agents as it did in conformant SVG Tiny 1.1 User Agents."
Added section, How to Reference This Specification
'Document time' definition is added to the list of definitions.
Clarified in definition of SVG Document Fragment that nested 'svg' elements are unsupported elements.
Added a normative definition for bounding box, linked to relevant parts of the spec, clarified behavior of bounding box in terms of return values for elements not found, and with regard to animation.
Loosened restriction against returning a bounding box for non-rendered elements.
Added a normative definition for decorated bounding box.
Added a definition for "text content block element" to allow for consistency and extensibility.
'CSS units' renamed to 'optional units' as XSL uses them as well. Link to QName definition added.
In The Svg Element definition, added zoomAndPan attribute and clarified that, together with width and height, it establishes the intrinsic size of the element.
The exception thrown when modifying the 'version' and 'baseProfile' attributes via the DOM has been removed. Changing those attributes does not cause any behavioral change in implementation.
Small clarification to prefetch element to clarify that the metadata returned by the server is not overridden, merely examined to detect hint staleness. Interplay of 'mediaTime' and 'mediaSize' explained better.
Fixed typo in definition of class attribute. Now <list-of-names>.
Viewport scaling paragraph in 5.1.2 changed to: "Normally, SVG content is designed to be scalable. In order for the SVG content to scale automatically to fill the available viewport, it must include a 'viewBox' attribute on the 'svg' element. This describes the region of world coordinate space (the initial user coordinate system) used by the graphic. This attribute thus provides a convenient way to design SVG documents to scale-to-fit into an arbitrary viewport."
To 5.1.2 added: "Note: 'animateMotion' and 'animateTransform' are legal as children to 'svg' but don't apply to 'svg' parents (since the 'svg' element doesn't have a 'transform' attribute). They only have any effect if the xlink:href attribute is attached to them so they point to other elements."
Slight clarification in the switch definition, "bypassed" was removed.
Minor rewording of the snapshotTime example images.
Clarified section 5.9.2 on when elements become resolved.
Simplified requiredFormats to take a space-separated list of Internet Media types
Updated the description of the true value for 'externalResourcesRequired' to correctly state the target of the load event.

Clarified that shorthand properties are not expressed as presentation attributes.
In The TransformRef value, added EBNF.
In The transform attribute, added 'none' value.
In Units, removed the terms "absolute" and "CSS" when referring to unit identifiers.
In Intrinsic Sizing Properties of the Viewport of SVG content, removed the term "absolute" when referring to unit identifiers.
In The transform attribute, added 'none' value.
In The transform attribute, moved parts of bounding box discussion into a normative definition in intro.html, added link.
In The viewBox attribute, added EBNF to define syntax.
Updated the link to 'Recommended XML/GML 3.1.1 encoding of common CRS definitions'
Removed unused wording about unit identifiers, which did not apply to Tiny.
Changed description of stroking operation of the rect element (now we start with an elliptical arc and closepath)
Now preserve tbreak elements when editing text content. tspan elements are still stripped.
Multiple consecutive tbreak elements now cause multiple line-breaks.
Definition of 'auto' value for line-spacing harmonised with 'normal' value for XSL 'line-height'.
10.13: "For systems which have system clipboards, the SVG user agent is required to provide a user interface for initiating a copy of the currently selected text to the system clipboard." is changed to: "For systems which have system clipboards, the SVG user agent should provide a user interface for initiating a copy of the currently selected text to the system clipboard."
editable attribute is now consistently listed as animatable.
Added explanation and example for using pointer-events="boundingBox" with textArea to allow empty text inputs to activate via a pointer.
Removed comment about how the specification doesn't say how computed values for 'font-weight' are represented.

Added references to "text content element" or "text content block element" where appropriate.
In Specifying paint it has been clarified that <IRI> actually is: url(<IRI>).
In Specifying paint, it has been clarified that invalid IRIs must be treated as 'none'.
In Fill Properties changed the computed value from 'Specified value, except inherit' to '"none", system paint, normalized <color> value or absolute IRI'
In Stroke Properties changed the computed value from 'Specified value, except inherit' to '"none", system paint, normalized <color> value or absolute IRI'
In 'viewport-fill' property changed the computed value from 'Specified value, except inherit' to 'normalized <color> value, except inherit'
In Solid Color Element changed the computed value from 'Specified value, except inherit' to 'normalized <color> value, except inherit'
In The SVG 'color' property changed the computed value from 'Specified value, except inherit' to 'normalized <color> value, except inherit'
In 'stop-color' property changed the computed value from 'Specified value, except inherit' to 'normalized <color> value, except inherit'
Added 'The text-align' property as it had been accidently left of out of the previous working draft.
Added value of "none" to 'viewport-fill' property.
System paint clarified as a paint server, not a subtype of color.
Changed specific links to "bounding box" to point to the new bbox definition
Changed 'normalized' to 'specified' <color /> value for 'Computed Values'
Added references to decorated bounding box for selected attributes (stroke, stroke-width, stroke-linecap, stroke-miterlimit, and stroke-linejoin).
Added restriction on color keywords, such that they must be lowercase, for consistency.
Added additional wording at stroke-dasharray and stroke-dashoffset to cover linecaps on dashing, informative note on unspecified behavior and restarting dash-offset from scratch for subpaths
Added references to "text content element" or "text content block element" where appropriate.
The media type in the audio example is changed to "application/ogg".
The computed value of audio-level is corrected,and volumes can increase as well as decrease.
Added section Audio mixing for 'audio' and 'video' elements that explains how mixing of the audio for multiple audio and/or video elements is done. This was previously identically explained in both the audio and the video elements.
Made it clear that audio and video must reference the appropriate types.
In The 'video' element it has been clarified that the width and height attributes have no effect on the rendering if the transform behaviour is pinned. Also updated list of transformBehaviour values in attribute definition to be consistent with rest of section.
In The audio-level property, the type has been changed from <float> to <number>.
In Specifying navigation all the nav-* attributes used to have the IRI attribute value specified as url(<Local IRI>). This is changed to nav-* = url(<IRI>). And the following sentence is added to all nav-* attributes: "The specified element must be within the Current SVG Document Fragment."
In Navigation Behaviour we add that there should be a mechanism for escaping from a focus ring to the user agent.
In Complete list of supported events, a note stating that the load event does not bubble was added to the list and the paragraph at the end of the list that intended to say the same thing was removed.
In Complete list of supported events, the load event description was updated to better explain when the load event triggers.
In Complete list of supported events, the wheel event was changed to mousewheel, changed from an UIEvent to a MouseEvent, and put it in the SVG namespace.

Removed numerical argument in the DOMActivate event.
Specified default Eventbase-element for SVG Media Elements as being the element itself.
Added references to "text content element" or "text content block element" where appropriate.
The erroneous reference to XML Names in fragment identifiers was corrected to NCNames, per XPointer framework. The TransformParams token was corrected to TransformList.
Clarified svgView in fragment identifiers
Specifying traditional linking behavior as regard bare name fragment identifiers, such that the target element is brought into view, using decorated bounding box.
The Script Element definition text was updated to indicate that a script executes when it is loaded, and that inserting a script into the DOM tree will cause it to execute.
In The Listener Element the reference to removeEventLister was removed from the 2nd paragraph, and the note on the observer attribute from the same paragraph was moved to the attribute definition section.

Updated The Handler Element, correcting the statement about script execution semantics.
In Relationship to SMIL 2.1 Animation the discard element has been removed from the list. 'discard' is not an animation element.
In Attributes that control whether animations are additive px units from the small examples are removed since it is not legal in tiny.
Clarified that for attributeType="auto", all known CSS properties are searched, not just those defined by SVG.
In the second bullet list in 16.2.16 "skew" is replaced by "skewX" and "skewY"
