## Iris master
Coq 8.10, 8.11, and 8.12 are newly supported by this release, and Coq 8.7 and
8.8 are no longer supported.
This release does not have any outstanding highlights, but contains a large
number of improvements all over the board. For instance:
* `heap_lang` now supports deallocation as well as better reasoning about
"invariant locations" (locations that perpetually satisfy some Coq-level
* Invariants (`inv N P`) are more flexible, now also supporting splitting
and merging of invariants with respect to separating conjunction.
* Performance of the proofmode for BIs constructed on top of other BIs (e.g.,
`monPred`) was greatly improved, leading to up to 70% speedup in individual
files. As part of this refactoring, the proofmode can now also be instantiated
with entirely "logical" notion of BIs that do not have a (non-trivial) metric
structure, and still support reasoning about ▷.
* The proof mode now provides experimental support for naming pure facts in
intro patterns. See
[iris/string-ident]( for details.
* Iris now provides official ASCII notation. We still recommend using the
Unicode notation for better consistency and interoperability with other Iris
libraries, but provide ASCII notation for when Unicode is not an option.
* We removed several coercions, fixing "ambiguous coercion path" warnings and
solving some readability issues.
* Coq 8.10, 8.11, and 8.12 are newly supported by this release, and Coq 8.7 and
8.8 are no longer supported.
