# Which Problems Are Solved
When building zitadel through `go build` or using an IDE debugging tool,
ldflags are not passed by dedault. In the past this was taken care of by
the `make compile` command, which got replaced by NX. The `nx
@zitadel/api:build` command does not set the ldflags either. Only the
`pack-platform` command does.
Because the ldflags aren't passed, the `date` and other variables remain
empty in the `cmd/build` package. During init of the package, if the
`version` is empty it defaults to the `date` variable. When the `date`
field was empty, the parsed `dateTime` would default to `time.Now()`,
but the `date` variable remained empty, resulting in a empty version.
A consistently empty version string prevents upgrades of projections on
dev systems, as the version from the last run is used.
# How the Problems Are Solved
If date failed to parse and `dateTime` is set to Now, use the formated
string of `dateTime` as `date`.

# Which Problems Are Solved
Cached object may have a different schema between Zitadel versions.
# How the Problems Are Solved
Use the curent build version in DB based cache connectors PostgreSQL and
Redis.
