# Revision history for zeolite-lang
## 0.4.0.0 -- 2020-05-05
* **[new]** Allows modules to specify custom linker flags and private include
paths in `.zeolite-module`. This lets categories written in C++ depend on
external libraries written in other languages.
* **[behavior]** Adds optimization of dependency inclusion for categories that
are defined in C++ sources. This should eliminate linking in object files that
are not needed by the binary.
* **[behavior]** Adds checks to prevent a module from defining a category that
was declared in another module.
* **[breaking]** Updates the `.zeolite-module` format to require associating
externally-defined categories with the source files that define them. This
allows finer-grained linking of binaries and tests.
## 0.3.0.0 -- 2020-05-03
* **[breaking]** Updates syntax for discarding all returns to use `\` instead of
`~`. This will allow `~` to be used for bitwise-not later on. (Not to mention
that `~` was kind of ugly in that context.)
* **[breaking]** Cleans up multiple-`return` syntax by removing `{}`. This
applies to *both* the `return` and the assignment.
## 0.2.0.0 -- 2020-05-03
* **[breaking]** Requires that `concrete` categories defined in `.cpp` files be
listed as `external` in `.zeolite-module`. This allows the compiler to ensure
that all categories have a definition, which helps avoid linker errors.
* **[breaking]** Gives `.zeolite-module` configs a proper file format.
* **[new]** Adds version checking to cached module data.
## 0.1.3.0 -- 2020-05-01
* **[new]** Adds support for more versions of GHC.
## 0.1.2.0 -- 2020-04-28
* **[fix]** Fixes a parser issue with empty `{}` blocks following `scoped`.
* **[behavior]** Updates `cleanup` procedures to allow setting named-return
values. Previously, initializing a named return in `cleanup` was not
sufficient.
* **[behavior]** Updates `zeolite-setup` to unconditionally rebuild supporting
libraries. Incidentally, this causes all existing user modules to be out of
date.
## 0.1.1.0 -- 2020-04-27
* **[behavior]** Set the default output path for binaries to the module's path
rather than the current directory.
* **[new]** Allows a base path (`-p`) with recompile mode (`-r`).
## 0.1.0.0 -- 2020-04-27
* First version. Released on an unsuspecting world.
