About Bicep CLI

Bicep is a Domain Specific Language (DSL) for deploying Azure resources declaratively. It aims to drastically simplify the authoring experience with a cleaner syntax, improved type safety, and better support for modularity and code re-use. Bicep is a transparent abstraction over ARM and ARM templates, which means anything that can be done in an ARM Template can be done in Bicep (outside of temporary known limitations). All resource types, apiVersions, and properties that are valid in an ARM template are equally valid in Bicep on day one (Note: even if Bicep warns that type information is not available for a resource, it can still be deployed).
Bicep code is transpiled to standard ARM Template JSON files, which effectively treats the ARM Template as an Intermediate Language (IL).

What's new in 0.48.1

Features and Bug fixes
- Emit GA language version for NullableExisting and ThisNamespace (#20258)
- Make apiVersion optional in the Azure resource schema MCP tool (#20292)
- Fix diagnostic locations for inherited .bicepparam values (#20085)
- Refine docs command configuration and error handling (#20269)
- Add trusted cloud configuration (#20294)
- Custom clouds that aren't in the built-in list must now be allowed through the BICEP_TRUSTED_CLOUDS environment variable, the same way trusted registries work:
[{"resourceManagerEndpoint":"https://management.example.com","activeDirectoryAuthority":"https://login.example.com"}]
- Visualizer: improved resource discovery and creation (#20340)
- Separate resource-creation dock, better browsing and filtering, and API version selection that takes the deployment scope into account
- Fills in required resource properties and shows related diagnostics on the graph
- Common resource providers listed first when browsing
- Visualizer: undo/redo (#20356)
- Undo and redo resource creation, node moves, and Reset Layout with Ctrl/Cmd+Z, Ctrl/Cmd+Shift+Z, or Ctrl+Y
- Simpler communication between the visualizer and VS Code, and simpler visualizer internals

Arduino Builder

Arduino Builder 1.0.13

Arduino Builder is a standalone utility for viewing, compiling and uploading Arduino sketch files and compiled ELF or HEX files to Arduino boards with the Arduino serial programming interface, Arduino ISP or USBasp, without the need for the Arduino IDE. The app has a standard user interface with drop down menus to choose the data you need. The functions of the utility can be undertaken in 3 steps. When compiling is required, for uploading sketch file, Arduino Builder scans the sketch for referenced libraries and then builds the necessary libraries automatically. The distribution package contains Arduino 1.0.4 core and library files, AVR GCC compiler toolchain and AVRDUDE. Please be aware that as only the standard Arduino libraries are shipped with the utility, if you want to build with custom libraries, then you will need to place the library source code files with the identical directory name into /arduino/libraries directory.
