+### Changed
+
+- in `topology.v`:
+  + removed the pointed assumptions from `FilteredType`, `Nbhs`, 
+    `TopologicalType`, `UniformType`, and `PseudoMetricType`.
+  + if you want the original pointed behavior, use the `p` variants
+    of the types, so `ptopologicalType` instead of `topologicalType`.
+  + generalized most lemmas to no longer depend on pointedness.
+    The main exception is for references to `cvg` and `lim` that depend
+    on `get` for their definition.
+  + `pointed_principal_filter` becomes `principle_filter_type` and 
+    requires only `choiceType` instead of `pointedType`
+  + `pointed_discrete_topology` becomes `discrete_topology_type` and 
+    requires only `choiceType` instead of `pointedType`
+  + renamed lemma `discrete_pointed`to `discrete_space_discrete` 
+
+- in `function_space.v`:
+  + generalized most lemmas to no longer depend on pointedness.
+
+- in `normedtype.v`:
+  + remove superflous parameters in lemmas `not_near_at_rightP` and `not_near_at_leftP`
+  + lemma `continuous_within_itvP`: change the statement to use the notation `[/\ _, _ & _]`
+
+- moved from `numfun.v` to `cardinality.v`:
+  + lemma `fset_set_comp`
+
+- moved `summability.v` from `theories` to `theories/showcase`
+
+- in `lebesgue_measure.v`:
+  + remove redundant hypothesis from lemma `pointwise_almost_uniform`
+
+- moved from `lebesgue_measure.v` to `set_interval.v`: `is_open_itv`, and
+    `open_itv_cover`
+
+- in `lebesgue_integral.v`:
+  + lemma `nice_lebesgue_differentiation`: change the local integrability hypothesis to
+    easy application
+
+- in `ftc.v`:
+  + lemma `FTC1_lebesgue_pt`, corollaries `FTC1`, `FTC1Ny`: integrability hypothesis weakened
+
+### Renamed
+
+- in `set_interval.v`:
+  + `subset_itvS` -> `subset_itvScc`
+
+- in `topology.v`:
+  + in mixin `Nbhs_isUniform_mixin`:
+    * `entourage_refl_subproof` -> `entourage_diagonal_subproof`
+  + in factory `Nbhs_isUniform`:
+    * `entourage_refl` -> `entourage_diagonal`
+  + in factory `isUniform`:
+    * `entourage_refl` -> `entourage_diagonal`
+
+- in `lebesgue_measure.v`:
+  + `measurable_exprn` -> `exprn_measurable`
+  + `measurable_mulrl` -> `mulrl_measurable`
+  + `measurable_mulrr` -> `mulrr_measurable`
+  + `measurable_fun_pow` -> `measurable_funX`
+  + `measurable_oppe` -> `oppe_measurable`
+  + `measurable_abse` -> `abse_measurable`
+  + `measurable_EFin` -> `EFin_measurable`
+  + `measurable_oppr` -> `oppr_measurable`
+  + `measurable_normr` -> `normr_measurable`
+  + `measurable_fine` -> `fine_measurable`
+  + `measurable_natmul` -> `natmul_measurable`
+
+- in `lebesgue_integral.v`
+  + lemma `integrable_locally` -> `open_integrable_locally`
+
+### Generalized
+
+- in `derive.v`:
+  + lemma `derivable_cst`
+
+- in `lebesgue_measure.v`:
+  + lemma `measurable_funX` (was `measurable_fun_pow`)
+
+- in `lebesgue_integral.v`
+  + lemma `ge0_integral_closed_ball`
+
+- in `ftc.v`:
+  + lemma `continuous_FTC2` (continuity hypothesis weakened)
