 There are more containers in the `tanya.container` package.
 ### Immutability
 Immutability doesn't play nice with manual memory management since the
 allocated storage should be initialized (mutated) and then released (mutated).
 `immutable` is used only for non-local immutable declarations (that are
 evaluated at compile time), static immutable data, strings (`immutable(char)[]`,
 `immutable(wchar)[]` and `immutable(dchar)[]`).
 ### Unsupported features
 The following features depend on GC and aren't supported:
 - `lazy` parameters (allocate a closure which is evaluated when then the
 parameter is used)
 - `synchronized` blocks

 ### Release management
-Deprecated features are removed after one release that includes these deprecations.
+Tanya is still under active development and it isn't possible to provide great
 backwards-compatibility at this stage. This won't change until 1.0.0. Almost
 every release contains new features or API changes alongside bug fixes. Thus:
 - Patch releases add new functionality and bug fixes in a backwards-compatible
 manner
 - Minor releases contain API breakages
 - Major release number is always the same: `0.x.x`
 Deprecated functionality is where possible marked as such before getting
 removed. It is left in the library for one release: If 0.8.1 deprecates some
 feature, it is removed in the next release: 0.9.0.

+- Tanya favours generic algorithms therefore there is no auto-decoding. Char
 arrays are handled as any other array type

 - Complex numbers (`cfloat`, `cdouble`, `creal`, `ifloat`, `idouble`, `ireal`)
