# MinIO Client EDGE.2026-06-01T04-06-20Z Released: 2026-06-01 This edge build expands MinIO Client management capabilities with new top-level `mc kms` key management commands, Model Context Protocol (MCP) administration, Iceberg catalog migration for tables, and a dedicated `mc alerts` view of cluster alerts. It also brings broad improvements to healing visibility, lifecycle expiry tracking, license reporting, and log streaming, alongside a range of bug fixes across listing, retention, and the `mc support top` telemetry views. --- ## Downloads ### Binary Downloads | Platform | Architecture | Download | | -------- | ------------ | ------------------------------------------------------------------------------------- | | Linux | amd64 | [mc](https://dl.min.io/aistor/mc/edge/linux-amd64/archive/mc) | | Linux | arm64 | [mc](https://dl.min.io/aistor/mc/edge/linux-arm64/archive/mc) | | macOS | arm64 | [mc](https://dl.min.io/aistor/mc/edge/darwin-arm64/archive/mc) | | macOS | amd64 | [mc](https://dl.min.io/aistor/mc/edge/darwin-amd64/archive/mc) | | Windows | amd64 | [mc.exe](https://dl.min.io/aistor/mc/edge/windows-amd64/archive/mc.exe) | | Linux | amd64 (FIPS) | [mc.fips](https://dl.min.io/aistor/mc/edge/linux-amd64/archive/mc.fips) | ### Container Images ```bash docker pull quay.io/minio/aistor/mc:EDGE.2026-06-01T04-06-20Z docker pull quay.io/minio/aistor/mc:edge ``` Note: Homebrew is only available for RELEASE builds, not EDGE builds. --- ## New Features ### Key Management (KMS) - Added a new top-level `mc kms` command for KMS management operations, including `mc kms enable` to enable the internal KMS and `mc kms key` to create, rotate, and list keys as well as fetch master key status (#394). ### MCP Administration - Added `mc admin mcp` subcommands to configure Model Context Protocol access and manage MCP tokens with create, info, list, and remove operations (#437). - Refined the default MCP tool permission set exposed to clients (#496). ### Tables and Iceberg - Added `mc table migrate` to migrate existing Iceberg catalogs (including Nessie-backed catalogs) into MinIO-managed tables (#402). - Added `mc table maintenance` and a `mc table maintenance status` subcommand to manage and monitor table maintenance (#393, #442). - Added a `--partition` flag to `mc table create` for defining partitioned tables (#489). - Added a `tables` alias for the `table` command for more natural usage (#412). - Added table replication handlers and paginated responses for the tables admin status API (#457, #515). ### Lifecycle and Object Management - Added a lifecycle expiry status tracker under `mc ilm` to monitor object expiration progress (#501). - Added a `--purge-deleted` flag to `mc rm` to permanently remove already-deleted (delete-marked) versions (#492). - `mc ls` now shows the upload ID when listing incomplete multipart uploads, making it easier to target stalled uploads (#493). - Added CLI support for the new `UpdateObjectEncryption` API to change object encryption settings in place (#397). ### Diagnostics and Cluster Insight - Added `mc alerts` to display internal alerts surfaced by the MinIO server (#373). - Added `mc admin accesskey diagnose` to troubleshoot access key configuration and permission issues (#444). - Added `mc admin cluster services info` to report the status of cluster services (#448). - Added progress metrics and a watch mode to `mc admin decommission status` for live tracking of decommissioning (#429). - Added per-erasure-set last scan duration to bucket scan info, and `mc support top` scanner status now accepts an `ALIAS/bucket` path to scope results (#524, #525). ### Logging and Licensing - `mc log audit` and `mc log api` now accept multiple values for their filter flags (#523, #519). - `mc log api` now caps log entries with a single `--limit` flag for the total number returned; per-node limiting is handled automatically, so the older `--max-per-node` flag is no longer needed (#486). - `mc license info` now reports product, node count, and serial number (#517). - `mc admin group add` can now create empty groups without requiring members (#460). - Added healing statistics to healing status output (#487). - Added an event target listing backed by a dedicated server endpoint (#435). - `mc admin config` now supports dot notation, a compact tree view, and a `-v` verbose flag (#406). --- ## Bug Fixes ### Healing and Cluster Info - `mc admin heal` now shows `HEALING (another pass is scheduled)` instead of `QUEUED` when another drive in the same erasure set is actively healing (#530). - Fixed the heal UI incorrectly showing a grey status for healthy buckets (#464). - Fixed a panic in `mc admin info` for nodes that belong to multiple pools (#508). ### Listing and Object Operations - Fixed a bug where `mc ls` issued a redundant second GET request (#447). - Fixed `mc tag list --version-id` displaying the version ID twice (#504). - Clarified `mc retention info` output when a bucket is locked without a default retention configured (#518). - Added a warning when an IAM and bucket metadata export archive is incomplete (#505). ### Telemetry (`mc support top`) - Fixed a nil pointer issue in the `support top api` callback when aggregated API data was missing (#514). - Fixed `support top net` display for hosts with multiple network interfaces (#466). - `support top rpc` now pauses correctly during playback of recorded data (#481). ### Output and Transfers - Fixed progress bar and bandwidth reporting inaccuracies during transfers (#438). - Fixed table border rendering for visual consistency across commands (#522). - Fixed a table header styling issue in lipgloss `StyleFunc` (#498). - Trace connections now retry automatically when a remote server restarts or dies (#469). --- ## Improvements - Standardized error messages across commands for consistent wording and formatting (#455). - Introduced a unified path model for `mc table` commands for more predictable argument handling (#383). - `mc log audit` now renders the new server `Message` field directly (#516). - Moved snapshot maintenance to the warehouse level for clearer scoping (#463). - Refactored `mc rm` option handling for clarity and correctness (#430). --- ## Security & Compliance ### Software Bill of Materials (SBOM) This release includes comprehensive SBOM documentation in multiple formats: - [SPDX JSON](sbom-EDGE.2026-06-01T04-06-20Z.spdx.json) - Standard SBOM format - [CycloneDX JSON](sbom-EDGE.2026-06-01T04-06-20Z.cyclonedx.json) - Security scanner compatible - [Go Modules](go-modules-EDGE.2026-06-01T04-06-20Z.txt) - Human-readable dependency list SBOM files document all direct and transitive dependencies for security auditing and compliance requirements. --- ## Upgrade Instructions To upgrade mc: 1.
