Dear OCaml users,

New releases of zed, lambda-term and utop are coming!

changes:

- 
## zed 3.1.0 (2020-05-30)

  - Zed\_edit:
    - Set\_pos action
    - Insert\_str action

and notable changes:

- 
## lambda-term 3.1.0 (2020-05-30)

  - `LTerm_read_line` and `LTerm_vi`:
    - vi visual mode
    - register support

- 
## utop 2.6.0 (2020-05-30)

  - compatible with OCaml 4.11
  - switch to the new parser exposed since 4.11
  - Vi edit mode: register support

Below is an illustration, that I split and store parts of a phrase into two registers(a and b) within the visual mode and then assemble them together.

![utop.2.6](https://us1.discourse-cdn.com/flex020/uploads/ocaml/original/2X/7/7603f61b1c56b418d880c48e55600ed9255d68f2.gif)

Enjoy!

Thank you for taking on the support of utop and associated libraries, @kandu! This is a really important tool in teaching, and I use it extensively.
