-## Features
+## Lifecycle 
+
+### Breaking changes
+
+- Breaking change: remove tkigraph from {igraph} proper (#1474).
+- Breaking change: Hard-deprecate `get.edge()` and `layout.grid.3d()` which have been deprecated for 10 years (#1398).
+- Breaking change: use `rlang::arg_match()` in `igraph.match.arg()` (#1165).
+
+### In-progress deprecations
+
+We are working towards a more consistent interface, especially as regards function naming: ultimately we want the igraph functions to use snake case.
+Please update your scripts and codebases as soon as you can.
 
-- Update vendored C/igraph sources to igraph/igraph@d2e0f4eb567dfc505227c346a015bef574c4ccd1.
 - Add `independence_number()` as an alias of `ivs_size()` (#1522).
 - Add `get_edge_ids()` as an alias of `get.edge.ids()` (#1510).
+- Increase the deprecation signal to a warning for `hub.score()` and `authority.score()` both replaced by `hits_scores()` (#1352).
+- Soft-deprecate `erdos.renyi.game()` and `random.graph.game()` (#1509).

+### C library

+- Update vendored C/igraph sources to igraph/igraph@d2e0f4eb567dfc505227c346a015bef574c4ccd1.
+
+### New functionality
+
 - Support `fit_power_law(implementation = "plfit.p")` to compute the P-value (#1386).
-- Export `.from()` etc. with behavior similar to `dplyr::across()` (#1436).
 - Add `max_degree()` (#1403).
 - Add experimental `sample_chung_lu()` (#1416).
 - Rename methods available for `sample_degseq()` and add the `"edge.switching.simple"` method (#1376).
 - Weight support for `eccentricity()` and `radius()` (#1211).
 - Add some argument checking to `add_shape()` (#1478).
-- Remove functions deprecated before 1.0 (#1352).

-- Breaking change: use `rlang::arg_match()` in `igraph.match.arg()` (#1165).
+- Export `.from()` etc. with behavior similar to `dplyr::across()` (#1436): functions like `.from()` are meant to be used inside `[` but now if an user misuses them, the error is more informative.
 
 ## Bug fixes
 
-- Add ellipsis to dummy functions `.nei()` and others (#1487).
-- Fix includig diagonal elements in dense adjacency matrices (#1437).
+- Fix including diagonal elements in dense adjacency matrices (#1437).
 - Align the body of `graph.lattice()` with its replacement `make_lattice()` (#1439).
 - Use `deprecated()` as default value for `circular` argument to `make_lattice()` (#1431).
 - `subgraph_centrality()` now ignores edge directions (#1414).
