#29993

Configuration: Each configured function can be implemented in either Java or TL-Script, using the same configuration syntax (including in the React configuration editor)

#30000

Design System UI pass, part 1: one selection form; surface-interactive-selected becomes surface-interactive-strong

#30006

Engine Extensions for the Tax Application: writable secret storage in the database, application context path in development mode (tl.contextPath), and instance search by attribute value

#30025

React UI: Hide commands and units for which the logged-in user does not have the required role on any object

#30031

The database does not enforce uniqueness of reference values without duplicates: a unique index on the link tables, separate link tables for bags

#30041

Self-service accounts: invitations expire and record their acceptance, invitations can be accepted and managed in the React UI, localized mail templates

#30045

View layer slots: report a <slot-content> that reaches no <slot>, empty fallback of a <slot>, slot positions in split panels and the sidebar

#30053

Agent runs: bound the pool of parallel tool calls (AgentLoop.TOOL_WORKERS) and tell a user whose chat message waits for a free worker

#30054

Agent screenshots belong to their chat: deleted with it, shown as thumbnails in the chat

#30057

Administration of the React UI: scheduler (task list, run now, stop, activate/deactivate, cluster lock, run history) with one unified active/inactive switch per task

#30058

Administration of the React UI: memory trend chart (memory use over time incl. garbage collection) and the remaining monitoring views of the classic UI

#30059

Administration of the React UI: maintenance functions of the classic maintenance pages (database export/import/history compaction, SQL console, reload, search index, security storage, encryption)

#30061

React UI: recent changes of the user with revert of a commit (user menu)

#30062

Model editor of the React UI: instance browser and instance import of the selected type

#30075

Log View (React UI): Display the details of an entry (stack trace) in a dialog in a readable format

#30076

#30081

TL Views: Change Authenticator App (New TOTP Secret), Reset Two-Factor Authentication by Administrator

#30086

XML import: <update> of <unless-known> must restate the structure of the descendants it updates

#30104

Nightly preview builds of the engine with a fixed Maven version and a changelog instead of a rolling SNAPSHOT

#30122

Remove TLDoclet exceptions in ext/javadoc/javadoc-ignores

#30126

tl-chat: Chat actions run as React commands within the window rather than via a separate ChatServlet; the chat's proxy workaround is no longer used in favor of engine polling

#30131

View layer: show the fallback of AttributeWithFallbackStorage as placeholder of a form field

#30132

View layer: value listeners of the model (<value-listeners>) react to field changes in the React form, through a UI-independent listener contract

Let a chat agent run page commands that the page of the chat allows, e.g. open a dialog

#30150

View layer: a value channel whose value is remembered per user

#30223

Self-service mails: texts editable in the service configuration, language of an invitation selectable

#30225

Model: handlers declared on an attribute (change) or a type (creation, deletion), run within the commit

#30227

Design System UI pass, part 1b: tables with depth and visible column boundaries

#30250

TL Views: <start-job> / <job-status> - close button for an ended job, point of no return, partial result of a cancelled job, closing the dialog from the follow-up, follow-up sees the job's commits

#30253

tl-ai-core pulls the Playwright browsers (driver-bundle, 200 MB) into every application: browser tools move into the optional module tl-ai-browser

#30199

React-Views: When a constraint is violated, the editable table displays only a red border, not an error message

#30204

React Table: When there are multiple row types, attribute columns are resolved only for the first type (label, sorting, filter)

#30205

#30257

React-UI: Commands from a window in a detached session generate two WARN lines per command

#30258

React-UI: The only way to display tabs for a single type is by using a type deviation in `access-control`, and that is logged as a WARN.

Exporting diagrams as SVG (reactFlowToSvg, flowToSvg) is not suitable for Batik or printing

TLScript

Problem

The SVG generated by reactFlowToSvg(...) cannot be rendered using pdfFile (Flying Saucer + Batik, embedded as <img src="data:image/svg+xml;base64,...">):

The engine sets `fill="transparent" ` or `stroke="transparent"`, including in `GanttLayoutOperations` and `GraphEdgeOperations` (tl-react-flow-common). Batik does not recognize "transparent " and terminates.
rgba(...)-colors are discarded by Batik.
The screen stylesheet is always embedded. It contains `var(--...)`, which is not resolved outside the browser.

The same applies to the flowToSvg(...) export of classic diagrams (tl-graphic-blocks-server): Colors from the script are carried over unchanged, and the embedded stylesheet tl-flow-core.css uses CSS variables.

Workaround in the application: The SVG is edited as text. ` transparent ` becomes ` none`, `rgba ` becomes ` rgb + fill-opacity`, and the stylesheet is removed. This requires a workaround using `parseCSV `; see the ticket “TL-Script: Read binary value as text.”

Expected

An exported SVG is portable:

`none ` instead of ` transparent`
`fill-opacity`/`stroke-opacity ` instead of ` rgba`
No stylesheet with CSS variables

Solution

reactFlowToSvg and flowToSvg always generate portable SVG that Batik (and thus pdfFile) can render. No option is needed; the display in the browser remains the same. The application can remove the workaround.

ColorFormat also supports the CSS notation rgb(r, g, b) / rgba(r, g, b, a) (channels 0–255 or percentages, alpha 0–1 or percentages). ColorFormat.parseColorOrNull returns null for text that is not a color.
The ` SvgTagWriter ` in both export lines converts `fill` and`stroke ` using `ColorFormat `: Each color is written as `#RRGGBB ` (including color names, e.g., ` black` as ` #000000`). A fully transparent color is rendered as `none`; the opacity of a partially transparent color is specified in `fill-opacity `/`stroke-opacity`, multiplied by an opacity value set on the element. Values that are not colors (`none`, `url(#...)`, `currentColor`) remain unchanged.
Instead of the on-screen stylesheet, the export embeds its own CSS2 stylesheet without variables (tl-react-flow-export.css or tl-flow-export.css in the classpath next to the respective FlowFactory), which only hides the selection markers. The on-screen display remains unchanged.

Test

TestColorFormat
TestSvgTagWriter in tl-react-flow-server and tl-graphic-blocks-server
TestFlowSvgPortable (tl-react-flow-server) and TestFlowPdf (tl-graphic-blocks-server): exported SVG without transparent, rgba(, and var(; rendering via pdfFile without Batik errors.
