Changelog.

API Migration to api.e-labs.co.uk

• Updates and licensing now go through the unified E-Labs API at https://api.e-labs.co.uk instead of Lemon Squeezy + slab.e-labs.co.uk
• Updater path moved from /api/slab/updates/latest to /v1/slab/updates/latest
• Auth header changed from X-API-Key to X-ELabs-Client-Key
• The previous slab.e-labs.co.uk updater stays alive so v0.2.8 users can still upgrade to this release; it'll be retired in v0.3.0

Licence System

• Replaced direct Lemon Squeezy calls with E-Labs API endpoints (/v1/slab/licence/{activate,check,deactivate})
• New stable per-install device ID (UUID) replaces Lemon Squeezy's instance_id
• Old licence data is automatically cleared on first launch — re-activate with your existing key
• Licence modal now shows your tier alongside email and key

Auto-Updater

• Fixed update endpoint returning HTTP 500 on every request — auto-updater was broken end-to-end since v0.2.7
• Update banner now correctly fetches and displays available versions

Editor

• Untitled tabs no longer locked into raw view — formatted/split modes now work on new blank tabs
• Line numbers toggle now works on Untitled tabs

Build & Branding

• Renamed app build env vars: MARKPAD_UPDATE_API → SLAB_UPDATE_API, MARKPAD_UPDATE_KEY → SLAB_UPDATE_KEY
• Silenced two Rust compiler warnings in P2P module

Main Branch Sync Release

• Merged the full v0.2.0 release line into main so main now includes the latest app updates, release pipeline fixes, and runner-feature integrations
• Preserved recent website/main behavior while carrying over the successful updater pipeline improvements from v0.2.x

Why this release

• Aligns branch strategy by making main the up-to-date source of truth before continuing 0.2.x releases
• Prepares a clean next patch release from fully synced history

Previous (v0.2.6)

Release Pipeline Completion Fix

• Fixed the updater merge/upload step to use explicit repository targeting when uploading latest.json, avoiding git-context failures in non-checked-out jobs
• Keeps the v0.2.5 endpoint normalization and action runtime updates, with final release publishing path now corrected end-to-end

Previous (v0.2.5)

CI Release Reliability Fix

• Updated GitHub Actions core steps to newer major versions to stay ahead of Node.js runtime deprecation warnings
• Hardened updater endpoint secret parsing to handle wrapped quotes, leading/trailing whitespace, trailing slashes, and case variations in the URL scheme
• Preserved strict release safety checks so local/private addresses are still blocked for production tags

Why this release

• v0.2.4 failed in CI because the endpoint validation rejected a secret value format that was effectively correct but differently wrapped
• This release keeps security checks while improving normalization so valid production URLs pass consistently

Previous (v0.2.4)

New Features and Editor Enhancements

• Merged RAW pane line number support and related editor improvements
• Added rich markdown extension improvements for better in-editor behavior and formatting
• Included recently merged bug and feature runner updates from v0.2.0

Website Download & Release Flow Improvements

• Improved website DMG lookup/download behavior for Mac architecture-specific releases
• Refined release detection and download handling paths used by the website client

Updater Endpoint Safety Fix

• Added release-time validation in CI to prevent accidental local/private updater URLs from being baked into production builds
• Publish workflow now fails fast if MARKPAD_UPDATE_API is empty, non-HTTPS, or points to localhost/private network ranges
• Standardized endpoint handling to trim trailing slashes before generating /api/slab/updates/latest

Previous (v0.2.3)

Branding Completion Release

• Finalized remaining Slab rebrand updates throughout the app so product naming, identifiers, and in-app messaging are fully consistent
• Updated app metadata and defaults to align with the Slab identity across startup content and runtime behavior
• Synced release version references to match this release and avoid mismatch with prior tags

Previous (v0.2.2)

Auto-Updater Fix

• Fixed latest.json missing aarch64 (Apple Silicon) platform entries — previously only x86_64 was included, causing "None of the fallback platforms were found" error on M-series Macs
• CI now merges updater JSON from both architecture builds into a single latest.json with all platforms
• Apple Silicon users can now receive and install updates correctly

Previous (v0.2.1)

Infrastructure & Branding

• Updated CI release pipeline to use "Slab" branding in release names and descriptions
• Migrated update proxy endpoint to new production URL (slab.e-labs.co.uk)
• Updated .env.example to reflect new Slab branding and production endpoint

Previous (v0.2.0)

Slab Brand Themes

• Introduced 3 new Slab brand themes: Muted, Light, and Dark
• Slab Muted is now the default theme, featuring the warm parchment palette from the Slab brand pack v1.5
• Slab Light offers a clean white-led surface with deep forest green accents
• Slab Dark provides a low-light reading experience with earthy tones
• Typography updated to brand fonts: Syne (headings), DM Sans (body), DM Mono (code)
• New Slab syntax highlighting theme for code blocks, using greens and earth tones from the brand palette
• Slab themes appear in their own submenu under View > Theme > Slab

Existing Themes

• All 9 previous themes (Clean Light, Warm Light, Cool Light, High Contrast, Material Dark, True Dark, Midnight Blue, Dracula, Nord Dark) remain available and unchanged
