# AIStor Memory (aimem) RELEASE.2026-09-23T02-59-13Z Released: 2026-09-23 A new `aimem history` command shows every version of a file in a Memory Bucket, and which session wrote each one. `aimem cortex` is renamed `aimem bucket`; the old name keeps working for now, but scripts that read the command's text output should be checked before upgrading. --- ## Downloads ### Binaries | Platform | Architecture | Download | | -------- | ------------ | ------------------------------------------------------------------------------------------------------------------------------------ | | Linux | amd64 | [aimem.RELEASE.2026-09-23T02-59-13Z](https://dl.min.io/aistor/aimem/release/linux-amd64/archive/aimem.RELEASE.2026-09-23T02-59-13Z) | | Linux | arm64 | [aimem.RELEASE.2026-09-23T02-59-13Z](https://dl.min.io/aistor/aimem/release/linux-arm64/archive/aimem.RELEASE.2026-09-23T02-59-13Z) | The setuid `aimem-fusermount` mount helper, the `aimem-bio` binary that `aimem bio` runs, and the Kubernetes CSI node driver are published beside it: | Binary | Architecture | Download | | ------------------ | ------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------- | | `aimem-fusermount` | amd64 | [aimem-fusermount.RELEASE.2026-09-23T02-59-13Z](https://dl.min.io/aistor/aimem/release/linux-amd64/archive/aimem-fusermount.RELEASE.2026-09-23T02-59-13Z) | | `aimem-fusermount` | arm64 | [aimem-fusermount.RELEASE.2026-09-23T02-59-13Z](https://dl.min.io/aistor/aimem/release/linux-arm64/archive/aimem-fusermount.RELEASE.2026-09-23T02-59-13Z) | | `aimem-bio` | amd64 | [aimem-bio.RELEASE.2026-09-23T02-59-13Z](https://dl.min.io/aistor/aimem/release/linux-amd64/archive/aimem-bio.RELEASE.2026-09-23T02-59-13Z) | | `aimem-bio` | arm64 | [aimem-bio.RELEASE.2026-09-23T02-59-13Z](https://dl.min.io/aistor/aimem/release/linux-arm64/archive/aimem-bio.RELEASE.2026-09-23T02-59-13Z) | | `aimem-csi-driver` | amd64 | [aimem-csi-driver.RELEASE.2026-09-23T02-59-13Z](https://dl.min.io/aistor/aimem/release/linux-amd64/archive/aimem-csi-driver.RELEASE.2026-09-23T02-59-13Z) | | `aimem-csi-driver` | arm64 | [aimem-csi-driver.RELEASE.2026-09-23T02-59-13Z](https://dl.min.io/aistor/aimem/release/linux-arm64/archive/aimem-csi-driver.RELEASE.2026-09-23T02-59-13Z) | Each binary has `.sha256sum`, `.minisig`, and `.asc` files at the same path. These links point into `archive/`, where a release's files stay after a newer release ships, so they always serve this build. The unversioned `…/linux-{arch}/aimem` path serves whatever release is newest. ### Packages `.deb`, `.rpm`, and `.apk` install the `aimem` client, the setuid `aimem-fusermount` mount helper (`/usr/bin/aimem-fusermount`, mode 4755), and `aimem-bio`. They also install a disabled example `mnt-aimem.mount` systemd unit and the `/sbin/mount.aimem` helper it needs. | Format | Architecture | Download | | ------ | ------------ | ------------------------------------------------------------------------------------------------------------------------------------------- | | DEB | amd64 | [aimem\_20260923025913.0.0_amd64.deb](https://dl.min.io/aistor/aimem/release/linux-amd64/archive/aimem_20260923025913.0.0_amd64.deb) | | DEB | arm64 | [aimem\_20260923025913.0.0_arm64.deb](https://dl.min.io/aistor/aimem/release/linux-arm64/archive/aimem_20260923025913.0.0_arm64.deb) | | RPM | amd64 | [aimem-20260923025913.0.0-1.x86_64.rpm](https://dl.min.io/aistor/aimem/release/linux-amd64/archive/aimem-20260923025913.0.0-1.x86_64.rpm) | | RPM | arm64 | [aimem-20260923025913.0.0-1.aarch64.rpm](https://dl.min.io/aistor/aimem/release/linux-arm64/archive/aimem-20260923025913.0.0-1.aarch64.rpm) | | APK | amd64 | [aimem\_20260923025913.0.0_x86_64.apk](https://dl.min.io/aistor/aimem/release/linux-amd64/archive/aimem_20260923025913.0.0_x86_64.apk) | | APK | arm64 | [aimem\_20260923025913.0.0_aarch64.apk](https://dl.min.io/aistor/aimem/release/linux-arm64/archive/aimem_20260923025913.0.0_aarch64.apk) | The packages depend only on libc (`libc-bin` / `glibc-common`); no `libfuse` is needed. ### Container Images ```bash # The aimem client, pinned to this release: docker pull quay.io/minio/aistor/aimem:RELEASE.2026-09-23T02-59-13Z # The Kubernetes CSI node driver, pinned to this release: docker pull quay.io/minio/aistor/aimem-csi-driver:RELEASE.2026-09-23T02-59-13Z ``` `quay.io/minio/aistor/aimem:latest` also points at this release, but moves when the next one ships. To verify a build, pin the release tag or a `@sha256:` digest, never `latest`. Mounting from a container needs `/dev/fuse` and `CAP_SYS_ADMIN` (or `--privileged`). ### Verification Each binary is signed with minisign (preferred) and GPG, and has a sha256sum file. ```bash BASE=https://dl.min.io/aistor/aimem/release/linux-amd64/archive curl -fsSLO $BASE/aimem.RELEASE.2026-09-23T02-59-13Z curl -fsSLO $BASE/aimem.RELEASE.2026-09-23T02-59-13Z.minisig curl -fsSLO $BASE/aimem.RELEASE.2026-09-23T02-59-13Z.sha256sum # minisign minisign -Vm aimem.RELEASE.2026-09-23T02-59-13Z \ -P RWTx5Zr1tiHQLwG9keckT0c45M3AGeHD6IvimQHpyRywVWGbP1aVSGav # sha256: the checksum file names the versioned binary, so keep that file name sha256sum -c aimem.RELEASE.2026-09-23T02-59-13Z.sha256sum ``` The minisign public key above is the MinIO release-signing key, used across the AIStor product line. --- ## Changes since RELEASE.2026-09-22T17-32-56Z ### New Features - **`aimem history /` shows who wrote each version of a file.** For every version the Memory Bucket holds, it prints when it was written, the user who wrote it, and the agent session, which a mount records from its `--session-file`. Use it to find which agent run produced a file without opening the console. `--limit` and `--after` page through long histories, `--annotations` lists the annotations on the current version, and `--json` gives output for scripts. (#206) ### CLI Changes "Cortex" was an internal name for a Memory Bucket. The CLI now says "Memory Bucket" everywhere. (#206) - **`aimem cortex` is now `aimem bucket`.** `aimem cortex` still works, but prints `` `aimem cortex` is deprecated; use `aimem bucket`. `` on stderr. A wrapper that merges stderr into stdout, or that fails on any stderr output, will see that line. - **`aimem secret provision --cortex` is now `--bucket`.** `--cortex` still works as a hidden alias. - **Text output has changed.** `no cortexes`, `deleted cortex `, ` is already a cortex` and ` is now a cortex` now say "Memory Bucket" instead. Scripts that match this text should use `--json` instead. - **Error messages have changed.** `cortex not found` and `cortex already exists` now read `Memory Bucket not found` and `Memory Bucket already exists`. When you try to mount a bucket that is not a Memory Bucket, the error now suggests `aimem bucket create`. - The skill files installed on each mount, the command help, and `aimem-bio`'s help and errors use the new name. No `aimem-bio` command or flag changed. ### Platform / Compatibility - Linux amd64 and arm64, glibc 2.34 or later. - Mounting needs `/dev/fuse`. FUSE passthrough also needs `CAP_SYS_ADMIN`; without it, a mount serves ordinary FUSE reads. --- ## Security & Compliance Software bills of materials (SBOMs) for this release, generated from the `Cargo.lock` files at the release tag: | Component | SPDX | CycloneDX | | ------------------ | ------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------- | | `aimem` | [aimem-RELEASE.2026-09-23T02-59-13Z.spdx.json](https://dl.min.io/aistor/aimem/release/notes/aimem-RELEASE.2026-09-23T02-59-13Z.spdx.json) | [aimem-RELEASE.2026-09-23T02-59-13Z.cdx.json](https://dl.min.io/aistor/aimem/release/notes/aimem-RELEASE.2026-09-23T02-59-13Z.cdx.json) | | `aimem-bio` | [aimem-bio-RELEASE.2026-09-23T02-59-13Z.spdx.json](https://dl.min.io/aistor/aimem/release/notes/aimem-bio-RELEASE.2026-09-23T02-59-13Z.spdx.json) | [aimem-bio-RELEASE.2026-09-23T02-59-13Z.cdx.json](https://dl.min.io/aistor/aimem/release/notes/aimem-bio-RELEASE.2026-09-23T02-59-13Z.cdx.json) | | `aimem-csi-driver` | [aimem-csi-RELEASE.2026-09-23T02-59-13Z.spdx.json](https://dl.min.io/aistor/aimem/release/notes/aimem-csi-RELEASE.2026-09-23T02-59-13Z.spdx.json) | [aimem-csi-RELEASE.2026-09-23T02-59-13Z.cdx.json](https://dl.min.io/aistor/aimem/release/notes/aimem-csi-RELEASE.2026-09-23T02-59-13Z.cdx.json) | The `aimem` dependency list is also published as plain text: [crate list](https://dl.min.io/aistor/aimem/release/notes/aimem-RELEASE.2026-09-23T02-59-13Z.crates.txt) and [dependency tree](https://dl.min.io/aistor/aimem/release/notes/aimem-RELEASE.2026-09-23T02-59-13Z.cargo-tree.txt). --- ## Upgrade Instructions - **Upgrading from a release before RELEASE.2026-09-22T17-32-56Z?** Read the [RELEASE.2026-09-22T17-32-56Z notes](https://dl.min.io/aistor/aimem/release/notes/release-notes-RELEASE.2026-09-22T17-32-56Z.md) too. They cover changes this release also contains, including the credentials a mount now needs for the `.aimem-lostfound/` prefix. - **Update scripts to the new command names.** Replace `aimem cortex …` with `aimem bucket …`, and `aimem secret provision --cortex` with `--bucket`. The old names still work in this release but print a deprecation warning. - **Check scripts that read text output or error messages.** Look for the words "cortex" or "cortexes" and switch the script to `--json`. - **Memory Buckets named `bucket` or `history`.** `aimem bucket …` and `aimem history …` are now subcommands, so `aimem bucket /mnt …` or `aimem history /mnt …` no longer mounts a Memory Bucket with that name. Mount it with the URI form: `aimem s3://bucket/ /mnt …` or `aimem s3://history/ /mnt …`. - **Kubernetes:** set the CSI node driver image to `quay.io/minio/aistor/aimem-csi-driver:RELEASE.2026-09-23T02-59-13Z`, which includes this `aimem`. ## Documentation - Hosted docs: ## Support - Security disclosures: security@min.io - Licensed customers and contributors: contact MinIO support.
