- Update to version 8.20.0. The most impactful changes are:
* A mechanism to add user-defined rewrite rules to Coq's reduction
mechanisms; see chapter "User-defined rewrite rules".
* Support for primitive strings in terms.
* Reduction of the bytecode segment size, which in turn means
that `.vo` files might now be considerably smaller.
- Notable breaking changes:
* Syntactic global references passed through the `using` clauses
of `auto`-like tactics are now handled as plain references
rather than interpreted terms. In particular, their typeclass
arguments will not be inferred. In general, the previous
behaviour can be emulated by replacing `auto using foo` with
`pose proof foo; auto`.
* Argument order for the Ltac2 combinators `List.fold_left2` and
`List.fold_right2` changed to be the same as in OCaml.
* Importing a module containing a mutable Ltac2 definition does
not undo its mutations. Replace `Ltac2 mutable foo :=
some_expr.` with `Ltac2 mutable foo := some_expr. Ltac2 Set foo
:= some_expr.` to recover the previous behaviour.
* Some renaming in the standard library. Deprecations are
provided for a smooth transition.

a different custom entry.
* Fixed `abstract` failure in the presence of admitted goals in
the surrounding proof.
* Fixed issues when using Ltac2 in VsCoq due to incorrect state
handling of Ltac2 notations.

- Update to version 8.19.0. The most impactful changes:
* Sort polymorphism makes it possible to share common constructs
over `Type`, `Prop` and `SProp`.
* The notation `term%_scope` to set a scope only temporarily (in
addition to `term%scope` for opening a scope applying to all
subterms).
* `lazy`, `simpl`, `cbn` and `cbv` and the associated `Eval` and
`eval` reductions learned to do head reduction when given flag
`head`.
* New Ltac2 APIs, improved Ltac2 `exact` and dynamic building of
Ltac2 term patterns.
* New performance evaluation facilities: `Instructions` to count
CPU instructions used by a command and Profiling system to
produce trace files.
* New command `Attributes` to assign attributes such as
`deprecated` to a library file.
- Notable breaking changes:
* `replace` with `by tac` does not automatically attempt to solve
the generated equality subgoal using the hypotheses. Use `by
first [assumption | symmetry;assumption | tac]` if you need the
previous behaviour.
* Removed old deprecated files from the standard library.
- Use %fdupes in the documentation package.

* The default locality of `Hint` and `Instance` commands was
switched to `export`.
* The universe unification algorithm can now delay the commitment
to a sort (the algorithm used to pick `Type`). Thanks to this
feature many `Prop` and `SProp` annotations can be now omitted.
* Ltac2 supports array literals, maps and sets of primitive
datatypes such as names (of constants, inductive types, etc)
and fine-grained control over profiling.
* The warning system offers new categories, enabling finer
(de)activation of specific warnings. This should be
particularly useful to handle deprecations.

priorities and the documented use of simple apply. This is a

relying on meta-level resolution such as type-classes or
canonical structures. Also allow coercions that do not fullfill
the uniform inheritance condition.

inductive types.

* The `typeclasses eauto` tactic has a new `best_effort` option
allowing it to return partial solutions to a proof search
problem, depending on the mode declarations associated to each

type inference to provide more precise error messages.

* The internal representation of match has changed to a more
space-efficient and cleaner structure, allowing the fix of a
completeness issue with cumulative inductive types in the type-
checker. The internal representation is now closer to the user-
level view of match, where the argument context of branches and
the inductive binders in and as do not carry type annotations.
* A new coqnative binary performs separate native compilation of
libraries, starting from a .vo file. It is supported by
coq_makefile.
* Improvements to typeclasses and canonical structure resolution,
allowing more terms to be considered as classes or keys.
* More control over notations declarations and support for
primitive types in string and number notations.
* Removal of deprecated tactics, notably omega, which has been
replaced by a greatly improved lia, along with many bug fixes.
* New Ltac2 APIs for interaction with Ltac1, manipulation of
inductive types and printing.
* Many changes and additions to the standard library in the
numbers, vectors and lists libraries. A new signed primitive
integers library Sint63 is available in addition to the
unsigned Uint63 library.

language, implemented using imperative persistent arrays.
* Introduction of definitional proof irrelevance for the equality
type defined in the SProp sort.
* Cumulative record and inductive type declarations can now
specify the variance of their universes.
* Various bugfixes and uniformization of behavior with respect to
the use of implicit arguments and the handling of existential
variables in declarations, unification and tactics.
* New warning for unused variables in catch-all match branches
that match multiple distinct patterns.
* New warning for Hint commands outside sections without a
locality attribute, whose goal is to eventually remove the
fragile default behavior of importing hints only when using
Require. The recommended fix is to declare hints as export,
instead of the current default global, meaning that they are
imported through Require Import only, not Require.
* General support for boolean attributes.
* Many improvements to the handling of notations, including
number notations, recursive notations and notations with
bindings. A new algorithm chooses the most precise notation
available to print an expression, which might introduce changes
in printing behavior.
* Tactic improvements in lia and its zify preprocessing step,
now supporting reasoning on boolean operators such as Z.leb and
supporting primitive integers Int63.
* Typing flags can now be specified per-constant / inductive.
* Improvements to the reference manual including updated syntax
descriptions that match Coq's grammar in several chapters, and
splitting parts of the tactics chapter to independent sections.
