# MinIO AIStor RELEASE.2026-04-14T21-32-45Z Released: April 14, 2026 This release delivers significant improvements to delta sharing token lifecycle management, including automatic garbage collection of expired tokens and a new relative expiry option that avoids client/server clock-skew issues. It also fixes internode communication when using separate internode ports and improves diagnostic error messages. --- ## Downloads ### Binary Downloads | Platform | Architecture | Download | | -------- | ------------ | --------------------------------------------------------------------------- | | Linux | amd64 | [minio](https://dl.min.io/aistor/minio/release/linux-amd64/minio) | | Linux | arm64 | [minio](https://dl.min.io/aistor/minio/release/linux-arm64/minio) | | macOS | arm64 | [minio](https://dl.min.io/aistor/minio/release/darwin-arm64/minio) | | macOS | amd64 | [minio](https://dl.min.io/aistor/minio/release/darwin-amd64/minio) | | Windows | amd64 | [minio.exe](https://dl.min.io/aistor/minio/release/windows-amd64/minio.exe) | ### FIPS Binaries | Platform | Architecture | Download | | -------- | ------------ | --------------------------------------------------------------------------- | | Linux | amd64 | [minio.fips](https://dl.min.io/aistor/minio/release/linux-amd64/minio.fips) | | Linux | arm64 | [minio.fips](https://dl.min.io/aistor/minio/release/linux-arm64/minio.fips) | ### Package Downloads | Format | Architecture | Download | | ------ | ------------ | ----------------------------------------------------------------------------------------------------------------------------------- | | DEB | amd64 | [minio_20260414213245.0.0_amd64.deb](https://dl.min.io/aistor/minio/release/linux-amd64/minio_20260414213245.0.0_amd64.deb) | | DEB | arm64 | [minio_20260414213245.0.0_arm64.deb](https://dl.min.io/aistor/minio/release/linux-arm64/minio_20260414213245.0.0_arm64.deb) | | RPM | amd64 | [minio-20260414213245.0.0-1.x86_64.rpm](https://dl.min.io/aistor/minio/release/linux-amd64/minio-20260414213245.0.0-1.x86_64.rpm) | | RPM | arm64 | [minio-20260414213245.0.0-1.aarch64.rpm](https://dl.min.io/aistor/minio/release/linux-arm64/minio-20260414213245.0.0-1.aarch64.rpm) | ### Container Images ```bash # Standard docker pull quay.io/minio/aistor/minio:RELEASE.2026-04-14T21-32-45Z podman pull quay.io/minio/aistor/minio:RELEASE.2026-04-14T21-32-45Z # FIPS docker pull quay.io/minio/aistor/minio:RELEASE.2026-04-14T21-32-45Z.fips podman pull quay.io/minio/aistor/minio:RELEASE.2026-04-14T21-32-45Z.fips ``` ### Homebrew (macOS) ```bash brew install minio/aistor/minio ``` --- ## New Features - **Relative token expiry for delta sharing** -- `CreateTokenRequest` now accepts an `expiresIn` duration field (e.g. `"720h"`) as an alternative to `expiresAt`, avoiding client/server clock-skew issues when setting token expiry (#4076) --- ## Bug Fixes ### Delta Sharing - **Token garbage collection now survives leadership failover** -- the GC goroutine previously exited permanently when a node lost leadership; it now re-acquires the leader lock and resumes collection (#4136) - **Expired tokens are now automatically cleaned up** -- a leader-only background loop (every 6 hours) scans and deletes expired tokens from storage and both indexes, preventing indefinite accumulation (#4076) - **Share deletion no longer orphans global index entries** -- if the global or per-share token index cannot be loaded, `deleteShareByID` now returns an error instead of proceeding with partial cleanup (#4076) - **Token index errors are now propagated** -- `deleteTokenInfo` previously returned nil even when index updates failed, masking inconsistencies (#4076) - **STS credential expiry capped for legacy tokens** -- tokens without explicit expiry now receive 30-day STS credentials on regeneration instead of the previous incorrect 365-day window (#4076) - **Table drop no longer deletes entire multi-table share** -- dropping a table referenced by a share now removes only that table and prunes empty schemas; the share is only deleted when no tables remain (#4076) - **Orphaned token index files cleaned up on share deletion** -- per-share token indexes are now unconditionally removed when deleting a share, preventing index file accumulation (#4136) ### Internode Communication - **Fixed query parameter handling on separate internode port** -- when using `--internode-port`, the peer REST server did not call `ParseForm`, causing query parameters to silently return empty strings for speedtest, binary update, cordon, and other admin-path operations (#4052) --- ## Improvements - **Cleaner inspect error messages** -- removed the internal `GetRawData:` prefix from inspect errors so that `mc support inspect` and the console UI display user-friendly messages (#4041) --- ## Security & Compliance ### Software Bill of Materials (SBOM) This release includes comprehensive SBOM documentation in multiple formats: - [SPDX JSON](sbom-RELEASE.2026-04-14T21-32-45Z.spdx.json) - Standard SBOM format - [CycloneDX JSON](sbom-RELEASE.2026-04-14T21-32-45Z.cyclonedx.json) - Security scanner compatible - [Go Modules](go-modules-RELEASE.2026-04-14T21-32-45Z.txt) - Human-readable dependency list SBOM files document all direct and transitive dependencies for security auditing and compliance requirements. --- ## Upgrade Instructions For detailed upgrade instructions, please read: https://docs.min.io/enterprise/aistor-object-store/upgrade-aistor-server/ Platform-specific upgrade guides: - **Linux/Bare Metal**: https://docs.min.io/enterprise/aistor-object-store/upgrade-aistor-server/upgrade-aistor-linux/ - **Kubernetes with Helm**: https://docs.min.io/enterprise/aistor-object-store/upgrade-aistor-server/upgrade-aistor-kubernetes-helm/ ### Support For enterprise support: - SUBNET Support: https://subnet.min.io - Documentation: https://docs.min.io
