Fixes in what export does to the copies of libraries it leaves out, and in
the migrations of swap slots and copy texts (Phase 3c).
- Drop library color refs in fills and strokes on detached export.
The binfile export that detaches libraries drops each reference to another
file. For colors it read only where the older format kept them
(:fill-color-ref-file and :stroke-color-ref-file on the shape and on text
nodes), so a library color ref inside :fills or :strokes, the current
format, stayed and the exported file pointed at a library it does not
carry (F57). Every color of the shape, its text nodes included, now goes
through cts/process-shape-colors, which detaches the ones that refer to
another file.
file-test: a fill ref inside :fills is dropped.
- Detach copies by where their refs and components point on export.
The binfile export that detaches libraries decided for each copy shape
from one file, the :component-file of the shape or of the closest head
above it, and then dropped its component and its :shape-ref together
(F52). That is wrong both ways:
- a library copy nested in a local component refers, in each copy of that
component, to the nested copy in the local main; using the head's own
library, its :shape-ref was dropped, and the next sync treated the shape
as one the copy added;
- a dropped link kept :touched, :remote-synced and :main-instance;
- the shapes stored in deleted components were not detached at all.
A shape's :shape-ref now points into the file of the component of the top
head of its copy, or of the closest swapped head above it, and the link
goes with the shape's other component attributes (ctk/detach-shape) only
when that file is another one. A head whose own component is in another
file stops being a head and loses :swap-group, but stays a copy while its
main shape is in this file. Deleted components' shapes are detached the
same way.
file-test: a dropped link loses :touched; a library copy nested in a local
component keeps its ref in the component's copy, and the file validates; a
deleted component's nested library copy is detached.
- Follow a swap slot's chain through the pages of its mains.
find-ref-id-for-swapped, which migration 0010 runs on files older than the
swap group, walks a swapped shape's ref chain to the main child its swap
slot names. It read each step's children from the page of the step's own
component, not from the page the step lives on, so when the mains of a
nesting sat on different pages it found nothing, and the migration then
removed a valid slot: the swap was lost (F56). Each step now goes on in
the container the ref lookup found it in.
file-test: the original ref of a swap is found with the mains on two
pages.
- Remove ctf/get-component-container-from-head.
Its last caller, the swap slot chain walk of migration 0010, now takes
each step's container from the ref lookup.
- Recompute copy texts touched with the content group alone.
Files older than the text override groups mark a copy text whose content
changed with :content-group alone. Sync reads that as nothing touched in
the text and writes the main's content, so the copy lost its text and
styles at the next sync of its main (F50). Migration 0034 converted the
later groups but left this one.
convert-text-overrides now also converts a copy text with :content-group
and no text group, reading it as allowing every text group: compared with
its near main, it takes the groups where it differs (all of them when the
near main cannot be reached). Migration 0035 runs it on files that already
passed 0034; a binfile import converts them with the other old text
groups, deferred as they are.
convert-text-overrides-test: such a copy takes the letters and styles that
differ, nothing where nothing differs, and through the migration.
text-sync-test: once migrated, the copy keeps its text and takes the
main's new size.

Penpot is the open-source design platform for teams that build digital products at scale.
Penpot’s key strength lies in giving you full ownership of your design infrastructure. Built on open source and designed for self-hosting, it puts teams in complete control of their design environment supporting strict compliance and governance requirements. Whether used in the browser or deployed on your own servers, Penpot works with open standards like SVG, CSS, HTML, and JSON.
Real-time collaboration strengthens this foundation, helping teams scale and bring design closer to the product through top-tier capabilities. Additionally, developers feel at home using Penpot, because design is expressed as code, enabling a direct translation and shipping products faster.
Best-in-class native Design Tokens provide a single source of truth between design and development. They ensure consistency, improve collaboration, and make it easier to manage complex design systems.
The MCP server takes it further by enabling multi-directional workflows between design and code. A powerful open API and plugin system makes the workspace programmable, enabling automation, AI-driven workflows, and integrations with the tools and systems you already use.
With CSS Grid and Flex Layout, teams can design responsive interfaces that behave like real code from the start.
Combined, these features turn Penpot into a full-stack design platform for building scalable design systems and fully integrated product development processes.
If your organization is scaling and needs extra support, we’re here to help. Talk to us

Why Penpot
Penpot connects design, code, and AI workflows through a code-based approach, making designs readable by developers and AI via the MCP server. This approach helps teams ship what’s actually designed and manage design systems at scale with powerful design tokens. As a self-hosted, open-source and real-time collaboration platform, Penpot offers full flexibility, security, and ownership without vendor lock-in. Learn more about why Penpot is the platform for your team.
Plugin system
Penpot plugins let you expand the platform's capabilities, give you the flexibility to integrate it with other apps, and design custom solutions.
Designed for developers
Penpot was built to serve both designers and developers and create a fluid design-code process. You have the choice to enjoy real-time collaboration or play "solo".
Inspect mode
Work with ready-to-use code and make your workflow easy and fast. The inspect tab gives instant access to SVG, CSS and HTML code.
Integrations
Penpot offers integration into the development toolchain, thanks to its support for webhooks and an API accessible through access tokens.
Building Design Systems: design tokens, components and variants
Penpot brings design systems to code-minded teams: a single source of truth with native Design Tokens, Components, and Variants for scalable, reusable, and consistent UI across projects and platforms.
Getting started
Penpot is the only design & prototype platform that is deployment agnostic. You can use it in our SAAS or deploy it anywhere.
Learn how to install it with Docker, Kubernetes, Elestio or other options on our website.
Penpot Enterprise
Penpot Enterprise is our paid plan for organizations that need to scale their design work across multiple teams with advanced governance, security, and administration. Manage teams and access from a centralized Admin Console, configure advanced permissions, and connect your identity provider through SSO. Available for cloud and self-hosted environments, it combines enterprise controls with Penpot’s open-source foundation and open standards.
