# Changelog
|
|
|
|
All notable changes to Ebox are documented here.
|
|
|
|
## 2.0.1 (Unreleased)
|
|
|
|
### Added
|
|
|
|
- Direct dependencies on the independent ECSS 0.1.0 cascade engine and TP 1.0.1 retained/reactive text runtime.
|
|
- ECSS-backed property schemas, selectors, stylesheets, inheritance, cascade layers, custom properties, computed values, and provenance for Box, Flex, and Grid nodes.
|
|
- Surface-scoped region handles through `ebox-region-resolve`, retained TP publication through `ebox-render-to-buffer` and `ebox-display-buffer`, and atomic handle/selector/viewport/scroll updates.
|
|
- Typography longhands and inherited foreground projection that keep text readable when child boxes override background colors.
|
|
- A public, nestable framework render-burst boundary that covers pre-commit allocation, shares interactive deferred GC ownership with Ebox commits, and restores batch GC settings without collecting at the boundary.
|
|
- A supported `ebox-transaction-participant-route` switch: v2 structured TP
|
|
registration is the default, while the complete v1 adapter remains available
|
|
explicitly and as the compatibility fallback for older TP manifests.
|
|
|
|
### Changed
|
|
|
|
- Package metadata now distinguishes builds with the public unmount/revision
|
|
boundary and SPI v2 compatibility surface from older 2.0.0 development
|
|
snapshots.
|
|
- ECSS is the only selector matcher and cascade winner. Ebox adapts node trees to ECSS subjects, interprets computed values for measurement/layout/paint, and classifies their layout impact.
|
|
- TP is the only live buffer writer. Ebox produces retained surface candidates and semantic dirty-owner plans; TP owns diff execution, marker-backed mounts, revisions, transactions, and rollback.
|
|
- Flex and Grid container/item declarations enter the same ECSS pipeline as ordinary boxes instead of maintaining a parallel style path.
|
|
- Region updates use opaque surface-scoped handles. The same declarative source may be mounted in multiple buffers without sharing live identity.
|
|
- A full declarative update that continues a committed native frame now computes
|
|
a complete selector-local style certificate before stable native eligibility.
|
|
Other full/local paths retain their existing O(changed) style work. Native
|
|
updates no longer commit replacement runtime nodes without computed styles,
|
|
and structural full-frame bootstrap remains available.
|
|
|
|
### Removed
|
|
|
|
- `ebox-pop-to-buffer`, `ebox-switch-to-buffer`, and the private erase-and-evaluate buffer writer they exposed.
|
|
- Ebox's duplicate selector parser/matcher and duplicate cascade winner.
|
|
- Bundled playground fixtures. Executable `.ebox` references live in the independent `ebox-playground` package.
|
|
|
|
### Migration
|
|
|
|
- Install ECSS 0.1.0 and TP 1.0.1, in either order, before Ebox 2.0.1.
|
|
- Replace numeric region-id mutation with `ebox-region-resolve` followed by `ebox-region-update` on the returned handle.
|
|
- Replace `ebox-pop-to-buffer` or `ebox-switch-to-buffer` with `ebox-display-buffer`, or call `ebox-render-to-buffer` when display is controlled by the caller.
|
|
- Ebox does not scan previously rendered text to reconstruct runtime identity. Remount the declarative source through Ebox 2.0.
