This release is a replacement for the 5.4.3 patch release. It was changed to a minor version because of some larger changes behind the scenes to pave the way for future support for live updates in Scheduler Pro and Gantt.

FEATURES / ENHANCEMENTS

• We have refactored a few features and changed their prototype chain. If you are importing those features directly, or are extending them, you need to use correct base class and import path: Grid/feature/RowReorder -> Scheduler/feature/RowReorder, Grid/feature/CellEdit -> SchedulerPro/feature/CellEdit, Scheduler/feature/Dependencies -> SchedulerPro/feature/Dependencies

BUG FIXES

• #7154 – FillTicks and Indicator placement is not correct after setting start date

You can find more information in updated guides and in this repository: https://github.com/bryntum/bryntum-salesforce-showcase#bryntum-salesforce-showcase
• We have created a public Salesforce org where this app is preinstalled. You can find link to it and login credentials on the updated examples page
• Scheduler beforeDependencyEdit event now supports async handlers (#7109)

BUG FIXES

• #4869 – REACT StateTrackingManager configuration triggering an error
• #6077 – TypeScript Model constructors should allow second param
• #6347 – Store idChange event not fired

FEATURES / ENHANCEMENTS

• This release introduces a new TimelineHistogram class which implements a grid with histogram charts displayed for rows in the time axis section. Please check the new "Timeline histogram" guide for more details
• The release also includes refactored ResourceUtilization and ResourceHistogram views which now better support TreeGroup and Group features, and provide some additional APIs for customization. For more details please check the new "Resource histogram" and "Resource utilization" guides and see the updated resourcehistogram and resourceutilization examples
• Gantt now supports setting the eventColor field on a Task to a pre-defined named color (red, green, blue etc.) or a CSS color value. This changes the background color of the rendered task bar. It is also possible to configure the Gantt with a default eventColor that applies to all tasks, overriding the default coloring (#857)
• The TaskCopyPaste feature has been enhanced to use a page-global internal clipboard and also supports the browser's native Clipboard API if accessible. This means that it is possible to copy and paste tasks between multiple instances of Gantt or other Grid-based components. It is also possible to copy a task and paste it inside a Spreadsheet app like (#4169)
• Setting scheduling direction is now supported on the task level. See the docs for direction field on the Task model for more details (#2131)
• Widget has a new config, maximizeOnMobile which takes effect only on floating widgets on a mobile device. It causes the widget to be maximized instead of positioned in order to accommodate the mobile virtual keyboard. This will make event editing much easier to use on mobile devices (#6522)
• On mobile devices, type : 'checkbox' is rendered as a slidetoggle widget. The API and value is the same, it is just a more appropriate UI for the platform
• We have also added default editors for the eventColor field. There is one in the TaskMenu feature's context menu and one in the TaskEdit feature's task editing panel. Just set showTaskColorPickers to true and the editors will appear (#3157)
• There is also a new EventColorColumn which can be added to any Gantt. It renders a colored element which the user can click and select a new color for each task (#3537)
• ANGULAR taskeditor demo has been updated to show use of showTaskColorPickers Gantt configuration option
• REACT taskeditor demo has been updated to show use of showTaskColorPickers Gantt configuration option
• VUE taskeditor demo has been updated to show use of showTaskColorPickers Gantt configuration option
• For a slightly better docs experience for most users, the docs browser now by default hides some more obscure APIs normally only used when implementing own widgets and features. Advanced users in need of these APIs can still opt in to see them using the Show menu in the docs browser
• Added a set of baseline columns: "Baseline start" (BaselineStartDateColumn), "Baseline finish" (BaselineEndDateColumn), "Baseline duration" (BaselineDurationColumn), "Baseline start variance" (BaselineStartVarianceColumn), "Baseline end variance" (BaselineEndVarianceColumn) & "Baseline duration variance" (BaselineDurationVarianceColumn). Used in the updated baselines demo

API CHANGES

• Because of the support for eventColor in Gantt (mentioned above), changes to the CSS classes coloring Gantt Tasks has been made. If your app customizes the task bar's background color, we would recommend you to take a look at the result after upgrading to this version. The most notable changes are that $gantt-task-hover-background-color and $gantt-task-parent-hover-background has been removed. Instead, hovering now adds a linear-gradient on top of the background color. Please read the Upgrade guide for more information
• The TaskCopyPaste feature's copyRow and pasteRow has been made asynchronous due to the enhancements mentioned above
• The TaskCopyPaste feature's beforeCopy and beforePaste events are now asynchronously preventable
• The ScaleColumn class has been moved from Pro to regular Scheduler classes. This should not affect your application unless it imports the class from its individual file (not the case for the vast majority of customers). The distribution still includes SchedulerPro/column/ScaleColumn.js file which is now an empty wrapper importing the class from its new location. The wrapper is there till the next major release so please update your code and import the file from its new location if needed (#6176)

LOCALE UPDATES

• Localization for the new class SchedulingDirectionColumn has been added. Keys are: SchedulingDirectionColumn.schedulingDirection, SchedulingDirectionColumn.inheritedFrom, SchedulingDirectionColumn.enforcedBy
• Localization for the new class SchedulingDirectionPicker has been added. Keys are: SchedulingDirectionPicker.Forward, SchedulingDirectionPicker.Backward, SchedulingDirectionPicker.inheritedFrom, SchedulingDirectionPicker.enforcedBy

API CHANGES

• DEPRECATED LocaleManager.registerLocale and LocaleManager.extendLocale are deprecated. LocaleHelper.publishLocale should be used instead.
• When configuring a Gantt with a time zone at initialization, and there's also a startDate and/or a endDate initially, those days will be treated as in local system time zone and will therefore be converted to the configured time zone.

API CHANGES

• Recently browsers have added support for Unicode 15, which changes the output of Intl.DateTimeFormat when formatting time to include AM/PM. Those browsers now use "thin space" (\u202f) instead of regular space. This affects the DateHelper.format() function, but likely you do not need to take any action in your application. It also affects DateHelper.parse(), which has been updated to support the new unicode space (#6193)

• The responsive state objects used in the responsive config of the Responsive mixin now support a once property to allow configs to only be set on first activation of the state
• The Core.helper.DateHelper class has a new method formatRange method which can format date ranges, as well as new formatting options for week numbers
• Added new feature TaskNonWorkingTime which highlights the non-working time of the tasks, meaning time intervals when they can not be worked on. Try it out in the new calendars demo (#3260)
• Baselines can now be styled by supplying cls and/or style as part of their data (#2873)
• The TreeGroup feature was reworked to allow manipulating the tasks in the generated structure, applying the same rules as in the original view
• PdfExport feature is refactored to render content directly. This significantly improves performance and robustness by eliminating component scrolling. This behavior is enabled by default. You can revert to the old behavior by setting enableDirectRendering config on the export feature to false. (#4449)
• Baselines are now exported to PDF (#4834)
• New fieldfilters demo showing how to add multi-filter UI to a Gantt
• ResourceHistogram has got a new generateScalePoints event that allows customizing its scale points at runtime (#5025)

LOCALE UPDATES

• Added localization for the new task split functionality, key EventSegments.splitTask

API CHANGES

• EventModel has new ignoreResourceCalendar boolean field. When field is set to true the event will not take its assigned resource calendars into account and will perform according to its own calendar only. (#3349)

BUG FIXES

• #336 – Task baselines need to track changes and modify Task
• #1947 – Update MSProjectImport demo to use the latest Maven
• #2422 – Wrong baselines dates should not cause crash
• #2755 – Task baselines are not imported correctly

• #5387 – Exporter throws exception when trying to render dependency to unscheduled task
• #5399 – MS Project import demo corrupts Japanese characters

FEATURES / ENHANCEMENTS

• New demo drag-resources-from-utilization-panel showing how to drag resources from utilization and drop on a Gantt row to assign the resource to a task.
• New records are assigned a generated id if none is provided. The generated id is meant to be temporary (a phantom id), and should be replaced by the backend on commit. Previously the id was based on a global counter incremented with each assignment. That simplistic scheme assured no two records got the same id during a session, but if an application serialized the generated id (note, they should not) and then reloaded it, it would eventually collide with a new generated id. To prevent this, the generated ids are now based on a random UUID instead
• Stores now by default show a warning on console when loading records that has generated ids, as a reminder that it should be replaced by the backend on commit

BUG FIXES

• #4645 – Improve error message "Bryntum bundle included twice"
• #4654 – REACT Bryntum widget wrappers don't accept all component properties in React 18
• #5312 – Crash when partnering with a hidden partner

• #5189 – Project throws exception when trying to apply changes for copied tasks hierarchy

FEATURES / ENHANCEMENTS

• An application's filters on a store may now be configured with an internal property. This indicates that they are fixed, and must not be ingested and modified by filtering UIs such as the Filter and FilterBar features (#4980)
• Configs that accept configuration options for a widget (or other class) are now (mostly) documented to accept a typed config object rather than a plain object. For example instead of {Object} tooltip - A tooltip configuration object, it is now {TooltipConfig} tooltip - A tooltip configuration object. This improves our TypeScript typings (transforms to Partial<TooltipConfig> in typings) when using such configs, but also improves our docs by linking to the configs of the type
• Gantt now supports using keyboard shortcuts for indenting and outdenting tasks. Defaults are Alt + Shift + Right for indenting, and Alt + Shift + Left for outdenting. Note that the Alt key matches the Option key on Mac Configurable with the KeyMap mixin **Guides/Customization/Keyboard shortcuts**
• Added a config to allow State Tracking Manager to ignore remote changes coming in a sync response. This allows user to only undo/redo local changes (ignoreRemoteChangesInSTM config on the ProjectModel) (#5083)

API CHANGES

• CalendarModel expanded field now defaults to true

BUG FIXES

• #3729 – Assignment field selection is cleared when picker store has a filter

• #5102 – Calendars missing unless parent calendar is expanded
• #5114 – Gantt SharePoint fabric demo fails on npm install

BUG FIXES

• #3427 – Infinite sync loop if percentDone value is incorrect

FEATURES / ENHANCEMENTS

• The Dependencies feature was refactored, it now continuously redraws dependencies during transitions. It also allows customizing the marker (arrow head) and applying a radius to line corners for a more rounded look
• Our TypeScript typings for string types that have a predefined set of alternatives was improved to only accept those alternatives. For example previously the dock config which was previously declared as dock: string is now dock : 'top'|'right'|'bottom'|'left'
• Create React App templates now available
• Configuring the crud manager functionality of the project was made a little easier by introducing shortcuts for setting load and sync urls using the new loadUrl and syncUrl configs
• Updated the built-in version of FontAwesome Free to 6.1.1
• Added new Angular Gantt + Resource Utilization combination demo
• KeyMap is a mixin that allows for standardized and customizable keyboard shortcuts functionality. KeyMap is by default mixed in to Widget and therefore available to all Widget's child classes. There is a new guide **Guides/Customization/Keyboard shortcuts** describing how to customize currently integrated keyboard shortcuts (#4300, #4313, #4328)
• Added applyProjectChanges method to the Project model which allows applying changes object from another project. Projects should be isomorphic
• Project optionally allows sync() calls without local changes, to retrieve changes from the backend. Configure forceSync : true to enable this new behaviour (#4575)

API CHANGES

• BREAKING ANGULAR Angular wrappers now use the more modern module bundle by default, instead of the legacy umd bundle. Hence application imports must be changed to match. This will slightly improve application size and performance (#2786)
• BREAKING gantt.lite.umd.js bundle is no longer available
• BREAKING WebComponents has been removed from gantt.module.js ES modules bundle. New bundle with WebComponents is gantt.wc.module.js

We hope you will enjoy this release and we are looking forward to hearing your feedback of what you would like us to develop next

/ Mats Bryntse, CEO @Bryntum

FEATURES / ENHANCEMENTS

• Added a new Resource Utilization view displaying resource allocation. Please check its demo for details (#2348)
• With this release Gantt starts displaying a popup informing users of scheduling conflicts, cycles and calendar misconfigurations. The popup allows the user to pick an appropriate resolution for the case at hand. On the data level the cases are indicated by new events triggered on the project (#1264, #1265)
• Gantt now performs the initial rendering of tasks quicker than before, by rendering them using raw data prior to performing calculations. Especially on large datasets this makes it feel much snappier. Requires loading normalized data to work optimally. Depending on how much non-UI manipulating your app does on the tasks the delayed calculations might affect your code, be sure to check out the upgrade guide (#2251)
• Gantt has a new TreeGroup feature that can transform the task tree on the fly. It generates a new tree structure based on an array of field names (or functions), each entry yields a new level in the resulting tree. Check it out in the new grouping demo (#3543)
• Each product has a new "thin" JavaScript bundle. The thin bundle only contains product specific code, letting you combine multiple Bryntum products without downloading the shared code multiple times (previously only possible with custom-built bundles from sources). Find out more in the What's new guide (#2805)
• Each theme is now available in a version that only has product specific CSS in it, called a thin version. These files are name product.theme.thin.css – gantt.stockholm.thin.css for example. They are intended for using when you have multiple different bryntum products on the same page, to avoid including shared CSS multiple times Read more about it in the What's new section in docs (#3276)
• Model has a new readOnly field that is respected by UI level editing features to disallow editing records having readOnly : true. It does not directly affect the datalayer, meaning that you can still programmatically edit the records (#665)
• Manually scheduled tasks are changed to not skip non-working time for proposed start/end date values. Check the upgrade guide if you want to revert to the previous behaviour (#2326)
• Added a pinSuccessors config that allows successors to stay in place by adjusting lag when dragging a task (#3998)
• Gantt's task rendering now uses absolute positioning instead of translation to position the task bars. This was changed to match changes in Scheduler and Scheduler Pro (#4055)
• New ParentArea feature highlighting the area encapsulating all child tasks (#1290)
• New ProjectModel setters/getters for assignments, calendars, dependencies, resources, tasks, timeRanges (#4043)
• New highlight-time-spans demo showing how to visualize time spans
• New grid-regions demo showing how to place columns on the right side of the timeline
• window references are replaced with globalThis which is supported in all modern browsers and across different JS environments (#4071)
• Gantt now triggers beforeMspExport and mspExport events when MspExport feature is used (#3565)
• A new function called downloadTestCase() was added to Bryntum widgets, it is intended to simplify creating test cases for reporting issues on Bryntum's support forum. Running it collects the current value for the configs your app is using, inlines the current dataset and compiles that into a JavaScript app that is then downloaded. The app will most likely require a fair amount of manual tweaking to reproduce the issue, but we are hoping it will simplify the process for you. Run gantt.downloadTestCase() on the console in a demo to try it
• Updated FontAwesome Free to version 6, which includes some new icons sponsored by Bryntum in the charts category: https://fontawesome.com/search?m=free&c=charts-diagrams&s=solid
• When configured with a StateProvider and stateId, Gantt state is stored automatically as stateful properties change (#1859)
• You can now style CalendarIntervals by providing a cls field in their data. This makes it very easy to style non working time elements (#3255)
• WRAPPERS Gantt has a new ProjectModel framework wrapper available for React, Vue and Angular. It simplifies sharing data between multiple Bryntum components (#4877)
• ANGULAR New demo showing use of inline data. Demo located in examples/frameworks/angular/inline-data folder
• REACT New demo showing use of inline data. Demo located in examples/frameworks/react/javascript/inline-data folder
• VUE New demo showing use of inline data. Demo located in examples/frameworks/vue/javascript/inline-data folder
• VUE-3 New demo showing use of inline data. Demo located in examples/frameworks/vue-3/javascript/inline-data folder For more details, see What's new and Upgrade guide in docs

API CHANGES

• BREAKING The Engine ResourceAllocationInfo class allocation property has been changed from an Array to an Object with two properties total and byAssignments. The total property contains an array of the resource allocation intervals. And the byAssignments is a Map keeping individual assignment allocation intervals with assignments as keys and arrays of allocation intervals as values Please check Upgrade guide if your code uses that class
