fiskaltrust.Middleware 1.3.22 (Germany)
August 16, 2021
In this version of the Middleware, we have added support for the certified version 2 of the fiskaly Cloud TSE. Additionally, some minor issues in the DSFinV-K related to transformed PayItems were resolved, and we've introduced a mechanism to reduce the Middleware's memory consumption in some scenarios.
Feature: Support for the certified fiskaly Cloud TSE
The Middleware now supports version 2 of the fiskaly Cloud TSE. As this is the first certified version - which means that previously existing v1 installations need to migrate to v2 -, we've introduced a new package name to avoid confusion about which version is installed.
To use the fiskaly Cloud TSE v2, the new package
fiskaltrust.Middleware.SCU.DE.FiskalyCertified must be used. This package does not support version 1 TSEs, which still can be used with the old
fiskaltrust.Middleware.SCU.DE.Fiskaly package while preparing the migration.
Due do legal regulations by fiskaly, existing TSEs can not be migrated to version 2, but new TSEs have to be created. Our objective is to make this switch as easy as possible, and we're in close contact with our partners and fiskaly to achieve this goal. A migration guide and some automation in the Portal will be released soon.
As of now, updating transactions is not supported by this SCU and will lead to an error with package version
-rc1. This is due to the fact that fiskaly does not allow to process update-transaction requests without a proper Process Type - which is not compatible with the Middleware's interface.
We've published an updated
-rc2 released, in which the update-transaction is not executed on fiskaly v2 TSEs. The Middleware returns an empty result in these cases, the call does not fail.
Stability improvement: Fiskaly v1 client update
We've updated the fiskaly client packages in our
fiskaltrust.Middleware.SCU.DE.Fiskaly SCU, which should lead to increased stability and performance. While we strongly recommend switching to legally compliant v2 TSEs, we've introduced this (most likely last) update into our v1 SCU to hopefully reduce some instabilities our partners have been experiencing in the last weeks.
Stability improvement: Automatically clean up memory after cloud uploads
As we're using .NET for our products, cleaning up memory manually is usually not required. However, some of our partners noticed increasing memory consumption by the Middleware, which (according to our investigations) are caused by fragmentation of the Large Object Heap (LOH). Unlike other objects, the LOH is not compacted automatically (only under specific circumstances). As some objects in the German Middleware tend to be large enough to end up in the LOH, this could lead to a fragmented LOH over time in some situations.
We've altered our HelipadUpload helper, which automatically runs each 5 minutes to upload data, to compact and collect the LOH after each upload. As this is an asynchronous process, the performance of the Middleware is not impacted by this change.
Bug fix: Amount and quantity were not converted correctly to DSFinV-K business cases in some edge cases
We've altered our DSFinV-K implementation, as the amount and quantity was not correctly transformed from PayItems in some rare use-cases. The issue should now be resolved, this change is backwards-compatible to existing data.
Packages not listed here were not updated, as we decided to not increase the version of unchanged packages. All packages with versions greater or equal to 1.3.1 are compatible with each other (it is e.g. possible to use fiskaltrust.Middleware.SCU.Swissbit.1.3.1 with the new queue packages).
- fiskaltrust.Middleware.Queue.EF v1.3.22
- fiskaltrust.Middleware.Queue.MySQL v1.3.22
- fiskaltrust.Middleware.Queue.SQLite v1.3.22
- fiskaltrust.Middleware.SCU.DE.FiskalyCertified v1.3.22-rc1
- fiskaltrust.Middleware.SCU.DE.Fiskaly v1.3.22
- fiskaltrust.Middleware.Helper.Helipad v1.3.22
Next steps in the Middleware
As the upcoming, certified version of the fiskaly TSE will be released in a few days, we will make sure to properly test and then release our updated SCU as soon as possible afterwards. Additionally, we will provide templates for cash registers' process documentations (Verfahrensdokumentationen). As always, we're happy to hear feedback and suggestions via email@example.com or directly via issues in our GitHub repositories.
