There was a lot of progress the last months, and now it’s time to provide a new release containing all the improvements. In this release, especially the library editor was heavily improved to make it more powerful and easier to use. See the highlights and the detailed changelog below.

Thanks a lot to all contributors and sponsors for pushing LibrePCB one step further!

Highlights

Design Rule Check for Library Elements (#381)

In virtually every EDA tool it’s easy to make mistakes when creating library elements like symbols or packages. Usually you notice such mistakes later in the schematic or board editors because of the ERC or DRC, so you have to go back to the library editor which costs time and nerves. Many projects try to solve this problem using documentation and design guidelines. But humans are generally lazy and don’t like to read those guidelines.

LibrePCB 0.1.1 goes a different way: It shows potential problems with library elements right in the library editor, so you can fix them immediately, i.e. before they are used in any schematic or board. And even better, for many of the warnings, the library editor provides the corresponding fix with just one click! Let’s see how it works:

Library Element Checks

More Powerful Symbol Variants (#430)

LibrePCB uses component symbol variants to support different graphical representations for the same component, for example to distinguish between American and European norms. See this talk at FOSDEM (slides here) for details.

Although this was already implemented in LibrePCB 0.1.0, it was not very powerful yet because in the “Add Component” dialog you had to select the desired symbol variant manually every time. As typically the European symbol variants were selected by default, it was especially annoying for Americans.

Now with the 0.1.1 release you can specify your preferred norm in the project settings, which will make the “Add Component” dialog pre-select the symbol variant which matches your preferred norm automatically! If you like to use American symbols, just add the norm “IEEE 315” to your project settings:

Transactional File System (#422)

This change is not directly visible to users, but it’s still noteworthy because it’s a very fundamental refactoring of the file system access of libraries and projects. The file system access is now transaction-based, which has several advantages:

  • More reliable save/autosave mechanism, making libraries and projects even more robust against file access issues or application crashes.
  • Cleaner software architecture, leading to less error-prone code.
  • Much more future-proof as it allows to implement features which were not possible until now.

Critical Bugfixes

Obround pads which are higher than wide (i.e. height > width) were rendered wrong in the package and board editors of LibrePCB 0.1.0. In particular, their orientation on screen was wrong by 90 degrees, while the Gerber output was correct. This release fixes the wrong orientation, so if you have any pad affected by this bug, it will now appear 90° rotated compared to the 0.1.0 release. See issue #424 for details.
