Recent updates
3.24.1
2026-01-17Release 3.24.1 focuses on fixing configuration auto-adjustment for virtual alignment in Rainbow CSV. It does not list any new commands or RBQL changes for this patch release.
3.24.0
2026-01-10Rainbow CSV 3.24.0 adds a new “Go To Column” command to quickly navigate to a specific CSV column. It also improves virtual alignment configuration auto-adjustment and fixes CSV autodetection behavior for small .csv files. The release includes an RBQL update, but the notes do not specify detailed query or compatibility changes.
Features3.23.0
2025-10-04Rainbow CSV 3.23.0 extends RBQL query capabilities and tweaks export behavior. It adds support for RBQL pipe `|` query chaining, removes the RBQL reliance on the legacy `python` (python2) command, and improves the Excel export command to respect the current selection range when specified.
BreakingFeatures3.22.0
2025-09-20This release focuses on improving virtual alignment reliability and adding new export commands. It also changes RBQL behavior by removing trailing spaces from fields by default, and removes an obsolete alignment feature that may have been used by some configurations.
BreakingFeatures3.21.0
2025-08-30Rainbow CSV 3.21.0 adds a new export command for Markdown and fixes sticky header alignment specifically in virtual alignment mode. It also removes an obsolete “scratch file alignment” feature, which was already superseded by virtual alignment.
BreakingFeatures3.20.0
2025-06-28Rainbow CSV 3.20.0 adds an export command aimed at Excel and Google Sheets, making it easier to copy query results in a spreadsheet-friendly format. It also changes RBQL behavior by removing trailing spaces from fields by default, which can affect queries that depend on exact string values including whitespace.
BreakingFeatures3.19.0
2025-04-05Rainbow CSV 3.19.0 includes a fix for a virtual alignment range issue. Between 3.11 and 3.19, the release notes indicate multiple behavioral changes and refinements around Virtual Alignment (inlay-hint based), including configuration/default tweaks and related UI improvements, plus several fixes to highlighting and alignment behavior.
BreakingFeatures3.18.0
2025-03-08Version 3.18.0 changes how Rainbow CSV performs field alignment in “virtual alignment” related modes, including where it adds readability padding. It also moves the Virtual Align configuration back into the extension’s JS code (global behavior) and adds an optional virtual vertical grid for improved table-like rendering.
BreakingFeatures3.17.0
2025-02-08Release 3.17.0 adds two user-facing capabilities to Rainbow CSV. It introduces alternate row background highlighting and an "auxiliary column" tracking feature, which likely improves how the extension understands or displays additional column-related data during CSV editing.
Features3.16.0
2025-02-01Version 3.16.0 contains a targeted fix for the extension's Virtual Alignment configuration. It resolves an issue by moving the Virtual Align configuration into the extension's package.json so VSCode can load it correctly.
