 # FSL base project changelog
 
+## 2101.3 (Thursday 14th January 2021)
 
-## 2101.0 (Monday 4th January 2020)
+ - The `$FSLDIR/etc/fslconf/fsl.sh` script now automatically adds
+   `$FSLDIR/share/fsl/bin/` to the `$PATH`, for official
+   (`fslinstaller`-installed) FSL installations.
+ - The `$FSLDIR/etc/fslconf/fsl-devel.sh` script now activates the `$FSLDIR`
+   conda environment, for official (`fslinstaller`-installed) FSL
+   installations.
+ - The `$FSLDIR/etc/fslconf/fsl-devel.sh` script now assigns default values
+   to `$FSLDEVDIR` and `$FSLCONFDIR`, if they are not set by the user.
+
+
+## 2101.2 (Friday 8th January 2021)
+
+ - Removed the legacy `bin/fsl_sub` script - `fsl-sub` is now available on
+   conda, so can be listed as a dependency of the `fsl/base` project.
+
+
+## 2101.1 (Tuesday 5th January 2021)
+
+ - Move contents of `config/common/` into `config/` - there is no need for
+   a separate directory level now that we aren't maintaining separate
+   configurations for different architectures/compilers.
+ - The default C++ compilation standard is now `-std=c++11` (previously
+   it was `-std=c++98`/`-ansi`).
+ - Allow projects to set custom C preprocessor flags, via `USRCPPFLAGS`.
+
+
+## 2101.0 (Monday 4th January 2021)
 
  - Moved the copyright insertion machinery (script and templates) from
    `config/common/` into `share/fsl/`.
