| 1 | +# Release History |
| 2 | + |
| 3 | +## [v14](https://github.com/smuehlst/circle-stdlib/releases/tag/v14) |
| 4 | + |
| 5 | +* Synced with [Circle Step 42](https://github.com/rsta2/circle/releases/tag/Step42). |
| 6 | +* Switched the FAT filesystem implementation to [FatFs](http://elm-chan.org/fsw/ff/00index_e.html). While FatFs offers more features than Circle's FAT filesystem implementation that was used previously, this release of |
| 7 | +circle-stdlib only aims to be compatible with previous releases regarding filesystem-related functionality. |

| 44 | + |
| 45 | +* Synced with [Circle Step 39.1](https://github.com/rsta2/circle/releases/tag/Step39.1). |
| 46 | +* AArch64 support. |
| 47 | +* Removed deprecated build script `build.bash` (use `configure` and `make` instead). |
| 48 | + |
| 49 | +## [v8.0](https://github.com/smuehlst/circle-stdlib/releases/tag/v8.0) |
| 50 | + |
| 51 | +* Synced with [Circle Step 39](https://github.com/rsta2/circle/releases/tag/Step39). |
| 52 | +* [mbed TLS](libs/mbedtls) support updated to release 2.16.0. |
| 53 | + |
| 54 | +## [v7.0](https://github.com/smuehlst/circle-stdlib/releases/tag/v7.0) |
| 55 | + |
| 56 | +* Synced with [Circle Step 37](https://github.com/rsta2/circle/releases/tag/Step37). |
| 57 | +* [mbed TLS](libs/mbedtls) support updated to release 2.14.1. |
| 58 | +* Circle is now included from its default repository. To sync an existing clone of the circle-stdlib repository, enter the following commands: |
| 59 | + |
| 60 | +```bash |
| 61 | +git submodule sync libs/circle |
| 62 | +git submodule update --init --remote libs/circle |
| 63 | +``` |
| 64 | + |
| 65 | +## [v6.0](https://github.com/smuehlst/circle-stdlib/releases/tag/v6.0) |
| 66 | + |
| 67 | +* Synced with [Circle Step 36](https://github.com/rsta2/circle/releases/tag/Step36). |
| 68 | + |
| 69 | +## [v5.0](https://github.com/smuehlst/circle-stdlib/releases/tag/v5.0) |
| 70 | + |
| 71 | +* Synced with [Circle Step 35.1](https://github.com/rsta2/circle/releases/tag/Step35.1). |
| 72 | +* Added support for <dirent.h> functions. |
| 73 | +* Added support for time()-related functions. |
| 74 | +* [mbed TLS](libs/mbedtls) support implemented by Rene Stange. |
| 75 | +* Added `configure` script and `Makefile` to replace `build.bash`. build.bash is |
| 76 | + deprecated and will be removed in a future release. |
| 77 | + |
| 78 | +## [v4.0](https://github.com/smuehlst/circle-stdlib/tree/v4.0) |
| 79 | + |
| 80 | +* Synced with [Circle Step 34](https://github.com/rsta2/circle/releases/tag/Step34). |
| 81 | +* Added CStdlibApp, CStdlibAppScreen, CStdlibAppStdio and CStdlibAppNetwork for |
| 82 | +easier application creation (thanks to Rene Stange). |
| 83 | + |
| 84 | +## [v3.0](https://github.com/smuehlst/circle-stdlib/tree/V3.0) |
| 85 | + |
| 86 | +* Synced with [Circle Step 33](https://github.com/rsta2/circle/releases/tag/Step33). |
| 87 | +* Implemented stdin/stdout/stderr based on Circle's CConsole class. |
| 88 | +* A build of circle-stdlib with ARM gcc toolchains that include Newlib out-of-the-box now provides |
| 89 | +support for C and C++ standard libraries. This is due to the fact that the Newlib provided by the toolchain |
| 90 | +is replaced by circle-stdlib's Newlib build, and the toolchain's standard C++ library works with the |
| 91 | +replaced Newlib. |
| 92 | + |
| 93 | +## [v2.0](https://github.com/smuehlst/circle-stdlib/tree/v2.0) |
| 94 | + |
| 95 | +This release implements Newlib's open(), close(), read() and write() |
| 96 | +system calls bases on Circle's I/O functions. This enables stdio functionality. |
| 97 | +A small [test program](samples/03-stdio-fatfs) demonstrates the use of |
| 98 | +stdio file system functions with Circle. |
| 99 | + |
| 100 | +## [v1.0](https://github.com/smuehlst/circle-stdlib/tree/v1.0) |
| 101 | + |
| 102 | +Initial build of Newlib with Circle, without any systems calls being implemented. |
