# 2026.4 - February 18 2026 Preview Release ## New Features * **Studio Versioning** - Production deployments will no longer auto-update with new releases, minimizing regression risk and enabling implementations to upgrade on their own schedule. Each org can select which official Studio Version is used for the player (embedded and platform), editor, and most jobs. Existing orgs will be set to the first version, which is the current state at the time of this release. New orgs will default to the latest version when provisioned. See guide [here](/platform-documentation/org-setup/project-settings/studio-versioning.md). ## Improvements & Bug Fixes * **Error Handling** - Resolved an issue where certain temporary service errors returned a 401 instead of a 503, which prevented automatic retries. * **Player** - Resolved an issue in the 2d player where fully transparent configuration layers were cropped to 1×1 pixels and then downscaled to 0×0 dimensions, resulting in 400 errors due to invalid image sizing.\*\* * **Player** - Resolved an issue in the 2D player where prefetched layer images were refetched on configuration change even if the layer images did not change.\*\* * **Product Import** - Resolved an issue where special characters were not being encoded in tag names. \*\*These fixes have already been deployed to production. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
