Release Notes

v0.5.0 — August 13, 2026

Highlights: Image preview in the result grid, refreshed brand identity, simplified environment model

New Features

  • Image preview in results — hover over binary or URL cells to preview images inline, with a reworked blob viewer for image payloads
  • "Mark as Image Column" override — manually flag columns the auto-detection misses from the column header menu
  • Simplified environments — the environment model is now Development, Staging, and Production; existing projects on the removed Local/Testing tiers migrate to Development automatically
  • Refreshed branding — new logo and app icon across the app and installer
  • Plan badge in the toolbar — your plan now shows as a pill next to the project name
  • In-app feedback prompt — a one-time prompt to share how Zentro is working for you

Fixes & Polish

  • FK join suggestions are now collected from every anchor in the statement, not just the first
  • Leading comments are stripped before classifying SELECT statements, so commented queries no longer trigger write-safety incorrectly
  • Backend session reconnects before switching project environment, fixing stale-connection errors after a switch
  • Write confirmations are no longer silently dropped in edge cases
  • Sandbox preview (eye icon) is now correctly gated behind Pro entitlement
  • Fixed stuck dialog nodes wedging Ctrl+Tab and other global shortcuts
  • Update checker now points at the ZentroIDE org repository
  • Patched Go and npm dependency vulnerabilities (Dependabot criticals/highs, transitive dompurify override)

v0.4.0 — July 28, 2026

Highlights: Adaptive SQL completion, spotlight-style Context Search, Keys panel rework, per-project instance lock

New Features

  • Adaptive SQL completion engine — tables and views are prioritized in suggestions; starter keywords no longer get an unwanted trailing semicolon
  • Statement run buttons — a run link above each detected statement via CodeLens, with the active statement highlighted as you move the cursor
  • Spotlight-style Context Search (Ctrl+E) — unified prefix-based search: schema objects by default, # for saved scripts, > for commands, @git/@env for branches/environments, : to jump to a line
  • Project workspace redesign — two-column create/edit wizard with an icon picker, a DBeaver connection importer, preloaded connections/schemas on project open, per-project instance lock with a distinct project color identity, and "Open in new window"
  • Inline database creation — create a new database directly from the database tree picker
  • Catalog object details viewer — inline diff view with a confirm-before-discard step for PostgreSQL, MySQL, and SQLite
  • Keys panel rework — tab-rail layout with real DDL previews
  • Query Statistics panel (Pro) — execution count, P95, and error rate, docked in the bottom panel
  • Safety awareness moved to Free — write-safety guardrails and environment strictness are foundational behavior, not a premium gate; Pro adds stricter enforcement (type-to-confirm, cooldown, reason field) on top
  • Export profile via a native OS save dialog
  • Feedback entry point in the toolbar — reports bugs/requests with app version, build, and OS attached automatically

Fixes & Polish

  • Fixed the editor not regaining focus after running a query from the editor itself (only worked from the toolbar/shortcut before)
  • Fixed the WHERE filter editor losing Ctrl+Z undo history every time the filter re-ran
  • Fixed table data types disappearing from the grid header while View Mode was on
  • Fixed a visual overlap between deleted/draft row states and the index column
  • Fixed transaction row totals being computed incorrectly for multi-statement runs
  • Fixed Space silently swallowing keystrokes instead of inserting a space while SQL suggestions were open
  • Hid internal Zentro housekeeping queries from the audit log and query statistics
  • Redesigned the ORDER BY sort-term popovers — pick ASC/DESC directly instead of a dropdown-plus-Save step

v0.3.0 — April 26, 2026

Highlights: Production Safety suite, ERD visualization, PII blur

New Features

  • Production overlay — persistent red banner when connected to a Production environment
  • Write confirmation prompts — write statements require confirmation on Production; stricter enforcement (type-to-confirm, cooldown, reason field) is Pro-only
  • Audit log — every query is logged locally with timestamp and status
  • Schema snapshots — automatic DDL snapshots before mutating schema changes; rollback to a prior snapshot is Pro-only
  • App lock — PIN protection on app open (Pro)
  • PII blur — mark columns as PII; values masked in Data Grid by default (Pro)
  • ERD visualization — auto-generated Entity-Relationship Diagram from live schema; pan, zoom, filter, export as PNG
  • Environment indicators — color-coded toolbar (blue / yellow / red) for Dev / Staging / Production

Improvements

  • Schema Explorer now shows estimated row counts per table
  • Auto-complete now resolves column names after a known table alias
  • Query execution time shown in the result toolbar
  • Improved error messages from database engine (less "unknown error")

Fixes

  • Fixed: switching environments in quick succession could cross-contaminate schema cache
  • Fixed: SQL Server NVARCHAR(MAX) columns displayed as empty in Data Grid
  • Fixed: app window position not restored correctly on multi-monitor setups

v0.2.0-beta — March 30, 2026

Highlights: Multi-tab editor, Saved Scripts, Query History

New Features

  • Multi-tab SQL editor — open multiple query tabs per connection
  • Saved Scripts — explicitly save and name frequently-used queries per project
  • Query History — automatic per-session history with search
  • Global search — search across saved script names and content from Context Search
  • Copy as — copy Data Grid selection as CSV, JSON, SQL INSERT, or plain text
  • Export — export full result set to CSV or JSON from the grid toolbar

Improvements

  • Connection test now reports specific failure reason (auth failure, host unreachable, SSL, etc.)
  • Data Grid: NULL values now display as a distinct badge instead of blank
  • Timestamps in Data Grid show UTC tooltip on hover

Fixes

  • Fixed: large result sets (1000+ rows) caused scroll lag in Data Grid
  • Fixed: PostgreSQL TIMESTAMPTZ columns parsed incorrectly in some locales
  • Fixed: app would occasionally hang on startup if default project was missing
