 # CHANGELOG
 
+## 1.0.11 (2021-03-20)
+
+This release introduces many improvements to the `media_type` library,
+together with several smaller improvements and some bug fixes (see
+below).
+
+### jgf
+
+= Fixed the use of an outdated standard library predicate in predicate
+  `jgf_reply/2`.
+
+### media_type
+
+- A big rewrite of how Media Types are stored.
+
+- A new Prolog type called `media_type` that is used to indicate Media
+  Type compound terms.
+
+- Better support for Media Types with identical file name extensions
+  (e.g., `gml` is used for Geography Markup Language and for Graph
+  Markup Language).
+
+- Removal of the following less used predicates: `extension_label/2`,
+  `media_type_comps/4`.
+
+- Changed the API for retrieving Media Type parameters: parameters are
+  now represented as pairs of atoms.
+
+- A new API for accessing 'families' of grouped Media Types:
+  `media_type_family/2`.
+
+### pagination
+
+- Fixed the use of an outdated predicate from the `dict` module in
+  predicate `pagination_options/5`.
+
+### string_ext
+
+- Added support for `inf` as the maxmimum length that is used in
+  `string_ellipsis/3`.  This makes it easier to specify that no
+  ellipsis should be applied in some contexts.
+
+### term_ext
+
+- New predicates for generating simple, ASCII-based IDs:
+  `ascii_id/[1,2]`.  These IDs are supported by many external
+  languages and tools (e.g., C names, DOT IDs).
+
+- Added a Prolog type declarations for optional types: `maybe(T)`.
+
+### tree
+
+- New module, based on a generalization of the old `proof` module.
+  This module current includes the following predicates: `depth/2` and
+  `shortest/2`.
+
 ## 1.0.10 (2021-03-17)
 
 This release fixes one bug in module `http_client2` and changes the
