MathType integrations release notes

• Fixed a bug that would make CKEditor 5 to ignore the arguments passed in the methods setData() and getData().
• Fixed a bug that would make specific styled formulas to make the equation render to stop working when processed.

• Improved the behaviour of the equation renderer. Before, when an equation failed to render, all the subsequent equations would fail. Now the renderer renders all correct equations and malformed ones don't make it abort the rendering of the correct ones.

• Updated the dependencies in our projects so they are compatible with the breaking change introduced by Node in Node v17

• Fixed a bug that would make equations to be pasted to times when using Froala 4.2
• Fixed a bug that would not allow the edition of the formula in the public MathType for CKEditor 5 Demo under certain conditions.

• After this release, customers will be able to use the parameter “wiriscustomheaders” in the configuration.ini file to set custom headers in wiris' HTTPS requests that can be modified dynamically. This tasks allows to modify the headers of the requests initiated by the MathType Viewer.

• Upgraded a dependency to a new major version. Having this dependency outdated caused some mathml tags to be removed when editing formulas, resulting in a different expression compared to the original one.

• Fixed a bug that would make equations to be pasted to times when using Froala 4.2
• Fixed a bug that would not allow the edition of the formula in the public MathType for CKEditor 5 Demo under certain conditions.

• Added a way to force Handwriting Mode when opening the MathType Editor without seeing the classic editor version. This can be set in the MathTypeParameters.

• Fixed a bug that would prevent adding more than 1 equation in Froala when using inline toolbar configuration.
• Fixed a bug that prevented formulas that contained a largeop operator in their MathML and all the subsequent formulas in the page to be rendered.
• Fixed a bug that would not set the language defined by the user in CKEditor5
• Fixed a bug that would make the content of equation to change under certain circumstances when editing already existant formulas in CKEditor.
• Created demos for Vue for html-integrations to offer customers the more information for integrating in this environment.
• Fixed an error that was launched when creating an equation after selecting a string of text in an html editor

• This release solves an issue that caused the viewer to render some characters inserted in MathType equations incorrectly, creating unexpected errors.

• In the demo of the Generic integration, we have included a "Handwriting-only" mode for those customers interested in this functionality alone.

The viewer (WIRISplugin.js) had a configuration that required users to download dependencies and build the package every time we updated it. With the change performed, we will be able to build and upload the package to NPM with the rest of the viewer files, which will simplify the user flow when we upload the viewer.

• We have fixed a bug that prevented our Froala and Generic Integration demos from properly setting the GUI parameters from the “advanced options" section.
• Also, the MathType for CKEditor 5 PHP demo hosted in store.wiris.com does not ignore the configuration.ini file anymore.
• Creating a new formula in "only handwriting mode” will not transition as the classic handwriting did.
• Fixed an error that appeared when double-clicking an equation in CKEditor 4 when the parameters “wiriseditorsavemode” in the configuration.ini was set to “base64”.

• Added zh_hant (Traditional Chinese) localization.

• Fixed some zh (Simplified Chinese) translation entries.
• Display the correct error message when services are used without a license.
• Avoid crashing when invalid values are used for the after attribute in a custom toolbar.

• We have included a "Handwriting-only" mode in the demo of the Generic integration so the customers interested in this feature can test it.

• The viewer (WIRISplugin.js) had a configuration that required users to download dependencies and build the package every time we updated it, thus creating a non-optimal user experience. 

After this release, we will build and upload the package to NPM with the rest of the viewer files, which will simplify the user flow when we upload the viewer.

• This release fixes a bug that prevented our Froala and Generic demos from adequately setting the GUI parameters from the "advanced options" section.
• Also, we have fixed a bug that made MathType for CKEditor 5 PHP demo ignore the configuration.ini file. From now on, it will take the parameter configuration into account.

• MathType for CKEditor Integration was doing an abnormal number of calls when using the Integration Services. The number of calls has been optimized to use fewer resources when using particular services.
• The ChemType icon in the toolbar was blurry for TinyMCE5 and TinyMCE6 Integrations. This has been fixed.

• Fixed a bug where the font and some font properties of the text changed after a formula was inserted through the web editor. Now the properties do not change anymore after a formula.
• Fixed a bug where the re-do action was not working in TinyMCE 6 and Froala. Now the re-do action works as expected.
• Fixed a bug where an error was displayed when adding to the website the contents edited with an HTML editor if some text was added before some LaTeX code. Now no error is returned.
• Fixed a bug where dragging and dropping an inserted formula with brackets would change the brackets to parentheses. Now the brackets do not change after being dragged and dropped.

• Now we generate "external integration" scripts for all our HTML Editors integrations, as an alternative installation method. These are served from our CDN.

• Vulnerability fix in our MT for Tiny6 integration.
• We have fixed a bug where the alt text was not adequately generated in our BlackBoard LMS integration.
• We have fixed a bug where hand-written formulae weren't filtered in CKEditor 5.
• We have fixed a bug that prevented the modification of LaTeX formulae when editing them in CKEditor 5.

• A bug that incorrectly displayed the rendered formulas after being inserted.
• A bug that prevented the MathType's modal window from being focused on the first open.

• You can download the package from NPM here. You will also find it in our integration services package or add the script in the HTML of the page.
• Our new render engine is now retro-compatible with older integration versions.
• This new render engine is open source, and you can find it in our Github repository wiris/html-integrations.
• It has a dynamic configuration allowing you to change its parameters.

• We have improved our handwritten formula parser to generate an exact MathML object than the editor formula parser.
• Froala bug fixes:
  • When clicking on the ChemType button, it works as expected
  • When an image is loaded before or after a formula, it works as expected
• CKEditor 4 bug fixes:
  • When clearing CKE4 contents right after inserting a formula, it works as expected
• Fixed inline widgets and caret misbehavior.
• Now preloaded formulas don't get misaligned when double-clicked.
• ChemType formulas won't be generated in italic anymore. Only MathType formulas will.
• CKEditor 5 integration runtime errors fixed on Vue.js projects.

• When copying/pasting a formula along with a “line break”, the line break was removed. Now it persists.
• When trying to edit a handwritten copy/paste formula by double-clicking it, it wasn't opened in handwriting mode. Now it is.
• When dragging and dropping a formula from one instance of the editor to another, the formula wasn't editable. Now it is.
• A memory leak was produced when destroying instances of our editor. The objects ClassicEditor and CKEditor5Integration weren't properly managed by the garbaged collector. Now they do, so the memory leak is gone.
• Custom toolbars that added the “<” and “>” symbols corrupted formulas, so they couldn't be rendered appropriately. Now they do.

• Send custom headers to the API requests.
• Globalization of the event handlers for opening and closing the editor.
• A friendly message alerting the users that the editor is offline and needs an internet connection to work.

• The integration will trigger a friendly pop-up alert to notify the editor has gone offline.
• The editor opening and closing event handlers have been exposed globally for them to be conveniently used.
• This new version allows the user to add custom headers to the editor's requests.

• Our staging server has been updated with changes to the test automation.

• Bugfix: The formulas edited using ChemType won't add an extra blank space between the math and xmlns tags.
• Bugfix: Now, the editor can insert an edited LaTeX formula when placed next to another rendered formula.
• Bugfix: Narrow screens are now handled as mobile, so the editor applies the proper properties.
• Bugfix: The integration for TinyMCE6 has been updated to handle the new TinyMCE API and pass the proper settings to the Wiris editor parameters. Consequently, our TinyMCE6 advanced options are functional back again.

• We got our integration services updated to be compatible with PHP 8.1
• Progressing in our automated test initiatives, we added a data-testid attribute in the interactable elements in the HTML-Integrations demos to work them in Cypress.
• The old telemetry component has been removed from the Devkit.
• A new telemetry class has been created in the Devkit to deal with Telemeter methods in our integrations.
• We added new telemetry events to our HTML Integrations.
• We removed the language configuration for consistency with the other editor demos, as it is already set in editorParameteres.

• We made the minimize and maximize modal buttons accessible via the tab.
• An alternative text has been given to the MT and CT icons for accessibility.
• The behavior of the “Cancel” and “Close” buttons of the editor and its confirmation modal has been fixed. It caused many focus/caret issues.
• DOMPurify for CKEditor5 was configured to accept necessary semantics and annotation tags.
• We have fixed internal issues when building TinyMCE demos.
• Add xmlns attribute to default formulas.
• When a Froala demo is opened, the editor is not focused by default, and we cannot insert formulas. Now we fixed that, and we can insert formulas at the beginning of the editor when this is not focused.
