# Which Problems Are Solved
When Zitadel starts the first time with a configured Redis cache, the
circuit break would open on the first requests, with no explanatory
error and only log-lines explaining the state of the Circuit breaker.
Using a debugger, `NOSCRIPT No matching script. Please use EVAL.` was
found the be passed to `Limiter.ReportResult`. This error is actually
retried by go-redis after a
[`Script.Run`](https://pkg.go.dev/github.com/redis/go-redis/v9@v9.7.0#Script.Run):
> Run optimistically uses EVALSHA to run the script. If script does not
exist it is retried using EVAL.
# How the Problems Are Solved
Add the `NOSCRIPT` error prefix to the whitelist.

# Which Problems Are Solved
The current "stable" release tag was no longer maintained.
# How the Problems Are Solved
Remove the tag from the docs.
# Additional Changes
Update the docs to reflect that test run with Ubuntu 22.04 instead of
20.04.

# Which Problems Are Solved
Scheduled handlers use `eventstore.InstanceIDs` to get the all active
instances within a given timeframe. This function scrapes through all
events written within that time frame which can cause heavy load on the
database.
# How the Problems Are Solved
A new query cache `activeInstances` is introduced which caches the ids
of all instances queried by id or host within the configured timeframe.
# Additional Changes
- Changed `default.yaml`
- Removed `HandleActiveInstances` from custom handler configs
- Added `MaxActiveInstances` to define the maximal amount of cached
instance ids
- fixed start-from-init and start-from-setup to start auth and admin
projections twice
- fixed org cache invalidation to use correct index

# Which Problems Are Solved
In eventstore queries with aggregate ID exclusion filters, filters on
events creation date where not passed to the sub-query. This results in
a high amount of returned rows from the sub-query and high overall query
cost.
# How the Problems Are Solved
When CreatedAfter and CreatedBefore are used on the global search query,
copy those filters to the sub-query. We already did this for the
position column filter.

# Which Problems Are Solved
There are some problems related to the use of CockroachDB with the new
notification handling (#8931).
See #9002 for details.
# How the Problems Are Solved
- Brought back the previous notification handler as legacy mode.
- Added a configuration to choose between legacy mode and new parallel
workers.
- Enabled legacy mode by default to prevent issues.
# Additional Changes
None
# Additional Context
- closes https://github.com/zitadel/zitadel/issues/9002

# Which Problems Are Solved

great user / developer experience.
# How the Problems Are Solved
Stop autoplay.

# Which Problems Are Solved
Slice initialized with a fixed length instead of capacity, this leads to
unexpected results when calling the append function.
# How the Problems Are Solved
fixed slice initialization, slice is initialized with zero length and
with capacity of function's argument
# Additional Changes
test case added

# Which Problems Are Solved
While running the latest RC / main, we noticed some errors including
context timeouts and rollback issues.
# How the Problems Are Solved
- The transaction context is passed and used for any event being written
and for handling savepoints to be able to handle context timeouts.
- The user projection is not triggered anymore. This will reduce
unnecessary load and potential timeouts if lot of workers are running.
In case a user would not be projected yet, the request event will log an
error and then be skipped / retried on the next run.
- Additionally, the context is checked if being closed after each event
process.
- `latestRetries` now correctly only returns the latest retry events to
be processed
- Default values for notifications have been changed to run workers less
often, more retry delay, but less transaction duration.

# Which Problems Are Solved
Instance domains are only computed on read side. This can cause missing
domains if calls are executed shortly after a instance domain (or
instance) was added.
# How the Problems Are Solved
The instance domain is added to the fields table which is filled on
command side.
# Additional Changes
- added setup step to compute instance domains
- instance by host uses fields table instead of instance_domains table
