One of the small but surprisingly impactful usability improvements for FileMaker developers is choosing a better font for scripts and calculations. While FileMaker's default editor font works reasonably well, it can sometimes make it difficult to distinguish between similar-looking characters.
Have you ever spent several minutes hunting down a bug only to discover that a lowercase l was used instead of the number 1? Or perhaps a capital O was mistaken for the number 0? These subtle visual ambiguities can lead to frustrating debugging sessions and wasted development time.

With the upcoming MBS Xojo Plugins 26.3 release, we introduce a new helper class:
AutoMutexMBS. This class makes working with mutexes safer and more convenient by
automatically releasing locks when an object goes out of scope.

Complete developer guide to storing, querying, and managing files in MongoDB GridFS
Introduction
GridFS is MongoDB’s mechanism for storing large files by splitting them into chunks and storing them across two collections.
The MBS FileMaker Plugin exposes a complete API for working with GridFS directly from FileMaker scripts.
This allows developers to treat MongoDB as a scalable file storage backend for images, documents, and binary data.

Today we try the new Persistent Data functions in FileMaker 26. A way to have per file global and persistent values. Use cases involve:
- Storing XML, JSON, JavaScript, HTML or any other large data block in the structure.
- Storing template PDF or images for logos
- Storing preferences in the file like window position. Then use Get(AccountName) or user id as instance ID.
- Storing data instead of a global variable.
This is not meant to store secure data like oauth keys. Everyone could potentially read the values and they are included in migration and with Save as XML!
Since every write causes a write to a file, it is a bit slower than a global variable. And this doesn't take part in transactions, so you may not want to write this together with multiple values to make sure they are either all written or none. This looks more like write once (or rarely) and read a lot.

If you work with different FileMaker solutions, testing environments, or customer deployments, there may be situations where you need multiple versions of FileMaker Pro installed on the same Windows machine.
Unfortunately, the FileMaker Pro installer is designed to prevent this. When it detects an existing installation, it typically refuses to install another version alongside it.
Fortunately, there is a workaround.

Modern applications increasingly rely on multi-threading: background tasks, network processing, rendering pipelines, and data caching often run in parallel. In such environments, shared mutable data structures become a critical source of bugs if not properly synchronized.
With AtomicDictionaryMBS introduced in MBS Xojo Plugins 26.3, we provide a dedicated thread-safe dictionary designed specifically for safe concurrent access in Xojo applications.
Why not just use a Xojo Dictionary?
The standard Dictionary in Xojo is not thread-safe. This means:
- Concurrent reads and writes can lead to crashes
- Race conditions can overwrite data unexpectedly
- Iteration while another thread modifies data can cause exceptions
- Complex locking must be implemented manually using Mutexes
In practice, this often leads to subtle bugs that are difficult to reproduce, especially in production environments where thread timing differs from debugging scenarios.
Developers typically solve this by wrapping a Dictionary in a Mutex, but this approach is error-prone:
- Locks may be forgotten for certain access paths
- Deadlocks can occur if multiple locks are used
- Fine-grained atomic operations are hard to implement correctly

Claris released version 26 of the FileMaker product family. As you may have noticed, the version number is finally synchronized to the current year. There are a lot of new features in this release:
- This release brings a lot of new AI integration. You can install a standalone Claris AI Server to handle the workload of AI queries. It is highly recommended to buy a separate machine with lots of RAM and a good GPU to speed up the queries. Mac Studios with M5 Max/Ultra may come handy soon.
Related to this are new comments for fields to help the AI know what a field is about. In FileMaker Pro you can use the Insert Image Caption script step to use an image model on the AI server to get image captions.
- Claris offers a built-in backup feature. Great to keep the hassle low and it allows the Claris Partner to sell it to their clients. The data is uploaded to cloud storage, preferable in a different region. Of course you must still run your own scripts to upload the nightly backups and all the hourly increments to your own backup server.
- Related to the backup is the standby server. A feature we had in FileMaker 14, but now with a different implementation. It is built on top of the incremental backups Changes are regularly transferred in batches to the standby server via SSH. Your clients can opt-in to this, get a second server and have it wait for a switch over in case of a disaster. But please have the standby server in a different location and on a different Internet provider.
- The installer for FileMaker Server can install just the tools. Great if you like to have the tools on your machine. Once you have the FMUpgradeTool, you may notice that it has a new trick: it can create a new database from an XML representation. Related to this are upgrades to the Save as XML script step and enhancements in the options so you can choose what to export.
- The OData interface got upgrades to better handle metadata. Since OData is the preferred way for AI to talk to FileMaker Server, this helps a lot with various integrations. Please note that Claris like to see you move to OData in favor of ODBC and Data API on the long term.
- There is an updated inspector for layouts. The layout is in context related and only shows features available for the currently selected items. This makes relevant options easier to find and cleans up the old interface. But since not everyone likes changes, you may be able to turn it off in the preferences soon. And this is macOS only as the Windows side is still in development.

We recorded the presentations at the MBS Xojo Conference in April 2026 and here is the Protecting Sensitive Data in Xojo: Practical Encryption Techniques Using MBS Plugins by Bill OKeefe.
Encryption is essential for protecting sensitive user and business data—but implementing it correctly is often confusing. In this practical session, building secure, efficient encryption workflows directly in Xojo using the MBS plugins will be shown.
Using the DICOM medical image format as a complex but relatable data model, we’ll explore how to handle mixed-type binary structures, manage endian differences, and work with Xojo’s MemoryBlock class to prepare data for encryption. From there, you’ll see real examples of AES-256 file encryption and decryption, key generation, chained encryption blocks, and performance optimization with the MBS Crypto classes.
Along the way we’ll cover common pitfalls (such as re-using IVs or ignoring data structure), when to use symmetric vs. asymmetric encryption, and how to keep your code aligned with regulatory standards such as FIPS 140 or HIPAA—even if you’re not working in medicine.
Attendees will receive a download code for working code fragments covering file, text, and database encryption techniques ready for adaptation in their own projects.

For our clients with plugin licenses for Monkeybread Software, we have a database with licenses and their email contacts.
Each license has multiple emails:
- a primary email for renewal reminders and newsletters about new versions.
- more emails as CC of licenses.
e.g. the administrator or developer to install the license.
- older alternative emails that are marked as old.
- sometimes an extra email just for invoices.
If you contact us with one of the emails and we search the database, we find your record.
When you buy a license for a client, we can put your email as developer in our database, so all communication goes through you. We would still like to know the name of the client and use it for the license keys.
Since you may disappear and clients still may need to renew, we appreciate having the client's email in the database as an alternative one. Then we can ask them directly if they like to renew. Since we do this for 20 years, we have seen multiple developers retire already.
When you order a license for a client in the web shop, you put in the billing address. That may be either the client itself if they pay themselves or your company if you buy it for the client and bill them later. When you use your address, consider adding somewhere a few letters for indicating which customer an order applies to. Or better email us the details for the client separately. If you order an update for one of your clients, we may apply it automatically to the one where we sent the last renewal reminder.
If you already have a couple of clients with MBS Plugin licenses, you can contact us if we should change the primary email for their licenses.

We got notice that Saxonica released the version 13.0 of their Saxon Library:
The first release of Saxon 13 has just been published. This is a new release
for Java, C#, C/C++, PHP, and Python. The highlights in this release are:
- A redesigned Schema API that allows multiple schemas to coexist. You can now validate
an input document with one schema and the result with another, even for the same namespace.
- More than 175 features from the draft 4.0 specifications are now available
in Saxon-PE and Saxon-EE, including:
- JNodes, path navigation over trees of JSON maps and arrays,
- Lookahead and lookbehind in regular expressions,
- Functions for CSV parsing,
- Functions for parsing with Invisible XML, and
- More flexible XML-to-JSON conversions with
fn:element-to-map.
- On the topic of 4.0,
- Mike recently published
a list of 101 new things you can do with Saxon using 4.0 features!
- (For more information about 4.0, see QT4CG.)
- Support for SaxonC extension functions written in C++, Python, and PHP.
- SaxonCS-HE, our first release of the free Saxon HE product built for .NET with C#.
For more details, please consult
the documentation.
If you encounter any issues with Saxon 13.0, please
report them
on our issue tracker.
Our MBS Plugins include Saxon 12.9 currently. We will soon review the new version and integrate it into MBS Plugins.
If any issues prevent that, we may report them and wait for the 13.1 version.
Our Saxon integration for FileMaker and Xojo is a powerful add-on to use XLST 3.0, XPath 3.1 and XQuery 3.1 in your solutions.
