Opensolr Changelog — Recent Updates & Improvements

Control Panel Mar 15, 2026

New Smart Fix Suggestions in Error Audit — the error table now automatically matches each error against the Opensolr documentation and suggests the right FAQ page to help you fix it. See a replication failure? A config XML error? A type mismatch? Click the suggested link and get step-by-step resolution. Works in both the per-index Error Audit and the Weekly Error Digest emails. Fully automatic — no setup required.

Improved Reload and Reset error messages in the Error Audit are now human-readable — raw Java stack traces are replaced with a short root-cause summary and a direct link to the Error Log for the full details.
Improved Index Reset is now bulletproof — the reset process verifies the index is actually empty after clearing it. If the standard reset fails (locked segments, corrupt index), it automatically falls back to a hard reset that nukes the data directory and rebuilds from scratch. Reset status is now properly reported back to the UI instead of always showing success.
New Communications Preferences — A new Communications page under Account lets you control which email notifications you receive. Toggle the Weekly Error Digest on or off at any time. Critical alerts (disk, bandwidth) and billing emails remain always-on to protect your service.
New Weekly Error Digest — Opensolr now sends a weekly email digest every Monday summarizing the top errors across your indexes from the past 7 days. Each index links directly to its Error Log in the dashboard. Account owners receive reports for all their indexes; team members only see the indexes they are assigned to. One consolidated email per person, no matter how many indexes you manage.

New API Usage now includes an endpoint filter — select any API method from the dropdown to see which users called it and how many times. Makes it easy to drill down into specific endpoints like ai_summary, stream_solr_log, or any other API action.
New Error Audit — every Solr error your index encounters is now automatically captured, classified, and stored for 7 days in a dedicated searchable index. The new Error Audit dashboard in the Control Panel gives you an error rate chart, severity and type breakdowns, full-text search across stack traces, date range filtering, and a detail view with root cause extraction and plain-English explanations. Find it in the left sidebar of any index, right below Tail Error Log.

Improved The Add New Index page now uses a sidebar filter panel instead of dropdown menus. Region, Version, Country, Type, and Crawler filters are always visible on the left, with result counts next to each value. Click any value to filter, click it again to clear. Active filters are highlighted and a Clear All link resets everything. On mobile, filters collapse behind a sticky Filters button at the top of the page.
Improved The Add New Index page is now more compact and easier to scan. Fonts, cards, and filter controls have all been tightened up so you can see more server options at a glance without scrolling. Each card shows the key details — Solr version, region, and server type — cleanly and without clutter.
Fix Error Log now catches all errors for your index, even when multiple different issues occur at the same time. Previously, errors with the same top-level message but different root causes were silently merged, and some Solr errors logged without the index name prefix were missed entirely. The dashboard now shows each distinct error with its actual root cause and a compact, readable stack trace.
