Release 1.44.1: DEV to main promotion
Explicitly set stack: cflinuxfs5 on every deployable module across all three MTA descriptors (.deploy/mta.yaml, root mta.yaml, mta-mcp.yaml) so modules no longer inherit the space-default cflinuxfs4 (Ubuntu 22.04), which SAP is retiring. cflinuxfs5 = Ubuntu 24.04. Modules pinned: tutorials-srv, tutorials-srv-qa, tutorials-srv-mcp (nodejs); tutorials-db-deployer, tutorials-db-qa-deployer (hdb); tutorials-approuter (approuter.nodejs). Resource modules (HDI containers, xsuaa, etc.) don't stage and take no stack. Also refresh a stale cflinuxfs4 rootfs reference in curl-transport.js. Validated: mbt validate -m schema passes clean (strict) on all three.

stack: cflinuxfs5on every deployable module across all three MTA descriptors. Previously no module declared a stack, so they inherited the CF space default (cflinuxfs4 / Ubuntu 22.04), which SAP is retiring (migration blog). cflinuxfs5 = Ubuntu 24.04.Modules pinned
.deploy/mta.yaml+mta.yaml.deploy/mta.yaml+mta.yaml.deploy/mta.yaml+mta.yamlmta-mcp.yamlResource modules (HDI containers, xsuaa, destination, credstore, etc.) don't stage and take no
stack. There's no MTA-global stack setting — it's per-module (confirmed in SAP MTA schema docs).cflinuxfs5is available in the target space (cf stacksconfirms Ubuntu 24.04). The mtaext files set no stack/buildpack, so the base-MTA value applies to every env (dev/qa/prod).Also refreshed a stale
