# MinIO Client RELEASE.2026-02-07T19-37-38Z

Released: February 7, 2026

This release introduces the `mc table register` command for registering existing Iceberg tables into the catalog, makes the `--schema` flag mandatory for `mc table create` to enforce explicit schema definitions, and fixes a display bug in `mc admin config set` output.

## New Features

- **`mc table register` command**: Register existing Iceberg tables into the catalog using their metadata files. Supports `--metadata-location` to specify the S3 path to the metadata JSON file and `--ignore-existing` to skip registration if the table already exists. (#380)

## Improvements

- **`mc table create` now requires `--schema`**: The `--schema` flag is now mandatory when creating tables. Previously, omitting it created a table with a generic default schema containing `id` and `data` fields, which was not meaningful for production use. When using `--ignore-existing` on an already existing table, the output now clearly indicates the provided schema was ignored. (#382)

- **Go 1.25.7**: Updated Go toolchain from 1.25.6 to 1.25.7. (#387)

## Bug Fixes

- **Fixed literal `%s` in `mc admin config set` restart message**: The restart suggestion after applying configuration changes displayed a literal `%s` instead of the server alias name. The message now correctly shows the alias. (#386)
