AppPack Changelog

Release date: 2026-09-24

Changed

Upgraded the AWS SDK.

cli v4.8.3

Release date: 2026-09-22

Fixed

Interactive prompts no longer hide the options listed above the default. Any select whose default wasn't the first option rendered only from the default down, so create app's "Public S3 Bucket" prompt defaulting to no showed no yes at all, and the instance-class pickers hid every class above the default. Pressing an arrow key revealed the missing options. Affects the yes/no addon prompts (private/public S3, SQS, database, Redis, Aurora, multi-AZ), the database and Redis instance-class pickers, and the database/Redis instance selectors.
config list -j works again. -j was a shorthand for --json on config list before 4.7.0 promoted --json to a global flag, and removing the global shorthand in 4.8.2 took config list -j with it. The shorthand is registered on config list again; --json continues to work everywhere.
The CLI now exits non-zero when it panics. A recovered panic was reported to Sentry and printed a message, but the process still exited 0, so CI jobs and scripts treated a crashed command as a success. The panic message now goes to stderr.

cli v4.8.2

Release date: 2026-08-10

Fixed

db load no longer fails with a shorthand collision error. Its --jobs/-j flag was clashing with the global --json/-j flag added in 4.7.0, breaking every db load invocation. --json no longer has a shorthand; db load -j <n> is unchanged.

cli v4.8.1

Release date: 2026-08-07

Fixed

create database now honors flags like --engine instead of re-prompting for them. Any flag you set explicitly (--engine, --instance-class, --multi-az, etc.) is used directly and its interactive prompt is skipped. --engine accepts the fully-qualified engine name (mysql, postgres, aurora-mysql, aurora-postgresql) and is validated so a typo fails fast.
create app/create pipeline now respect the --addon-database and --addon-redis flags, which were previously accepted but ignored. Interactively they preselect the addon; non-interactively they auto-select when the cluster has a single database/redis instance, and otherwise list the choices (use --addon-database-name/--addon-redis-name to pick one).

cli v4.8.0

Release date: 2026-07-24

Added

ps restart command to restart your app's processes. By default it does a graceful, zero-downtime rolling restart (spins up replacement containers before stopping the old ones); add --force to immediately stop the running containers and let them relaunch.
version check command to check if a newer CLI version is available.
version update command to download and install the latest CLI version from GitHub releases.
shell --live/ps exec --live now show each process's size (CPU/memory) in the selector, and print an advisory naming the process and its size after connecting.

Fixed

ps resize no longer fails on apps that have never had a successful release.
shell now only uses a login shell (bash -l) for buildpack apps, avoiding cases where it clobbered a PATH set by a Dockerfile-based app's image.
selfupdate now errors clearly when a downloaded binary exceeds the size limit, instead of silently truncating it to a confusing checksum mismatch.
Commands other than auth no longer fail with a raw SDK error when the local ~/.aws config has a partial/incomplete default profile.

ci-builder v2.7.0

Release date: 2026-07-23

Added

CodeBuild environment variables are now mapped to neutral, industry-standard CI
variable names and made available to builds — as --build-arg values for Docker
builds and as environment variables for buildpack builds:
CI_COMMIT_REF — source ref (from CODEBUILD_WEBHOOK_HEAD_REF, falling back to
CODEBUILD_SOURCE_VERSION for manual builds)
CI_COMMIT_SHA — resolved commit SHA (from CODEBUILD_RESOLVED_SOURCE_VERSION)
CI_BUILD_STARTED_AT — build start time (from CODEBUILD_START_TIME)
CI_REPOSITORY_URL — repository clone URL (from CODEBUILD_SOURCE_REPO_URL)
Each variable is only set when its source value is present, so Dockerfile ARG
defaults are preserved on non-CodeBuild or manual runs.

ci-builder v2.6.0

Release date: 2026-07-21

Changed

Removed support for EOL heroku-20 builds

Fixed

Builds that use an in-dyno test database or Redis add-on (heroku-postgresql:in-dyno,
heroku-redis:in-dyno) could intermittently fail during the pre-build phase with an
error like The container name "/db" is already in use. These add-on containers now
start with unique names, so a build no longer collides with a leftover container from
a previous run.

cli v4.7.0

Release date: 2026-06-24

Added

--json persistent flag for machine-readable CLI output.
modify app command to update some parameters of application/pipeline stacks.
build start command now accepts optional --ref flag to build from specific git references (branches, tags, or commit hashes).

Changed

create app/create pipeline now guide repository authentication through AWS Code Connections (GitHub App) instead of the deprecated CodeBuild OAuth flow.
Migrated interactive prompts from survey to huh.
Upgraded to AWS SDK for Go v2.
Updated to Go 1.25.4, upgraded go-jose to v4, and refreshed dependencies.

Fixed

Fixed issue where a stack update could revert unexpected parameters to template defaults.
ps resize no longer prints a misleading warning for release/scheduler processes.
Fixed destroy retry exit code.
Handle LoadBalancerNotFound during cluster deletion.
Added DynamoDB attribute tags so the SDK v2 correctly unmarshals stack items.

Fixed

Chart line layering: average values now render on top of max values, and response time percentiles render in correct order (p99 on top) for better visibility

dashboard

Release date: 2026-01-12
