+          }]
+      }]
+
+On this example, the express channel has at least 16.5 dB loss when crossing the ROADM express path with the corresponding impairment id.
+
+roadm-path-impairments is optional. If present, its values are considered instead of the ROADM general parameters.
+For example, if add-path specifies 0.5 dB PDL and the general PDL parameter states 1.0 dB, then 0.5 dB is applied for this roadm-path only.
+If present in add and/or drop path, roadm-osnr replaces the portion of add-drop-osnr defined for the whole ROADM,
+assuming that add and drop contribution aggregated in add-drop-osnr are identical:
+
+.. math::
+
+  add\_drop\_osnr = - 10log10(1/add_{osnr} + 1/drop_{osnr})
+
+when:
+
+.. math::
+
+  add_{osnr} = drop_{osnr}
+
+.. math::
+
+  add_{osnr} = drop_{osnr} = add\_drop\_osnr + 10log10(2)
+
+
+The user can specify the roadm type_variety in the json topology ROADM instance. If no variety is defined, ``default`` ID is used.
+The user can define the impairment type for each roadm-path using the degrees ingress/egress immediate neighbor elements and the roadm-path-impairment-id defined in the library for the corresponding type-variety.
+Here is an example:
+
+.. code-block:: json
+
+    {
+      "uid": "roadm SITE1",
+      "type": "Roadm",
+      "type_variety": "detailed_impairments",
+	    "params": {
+		    "per_degree_impairments": [
+		    {
+			    "from_degree": "trx SITE1",
+		      "to_degree": "east edfa in SITE1 to ILA1",
+			    "impairment_id": 1
+		    }]
+	    }
+    }
+
+It is not permitted to use a roadm-path-impairment-id for the wrong roadm path type (add impairment only for add path).
+If nothing is stated for impairments on roadm-paths, the program identifies the paths implicitly and assigns the first impairment_id that matches the type: if a transceiver is present on one degree, then it is an add/drop degree.
+
+On the previous example, all «implicit» express roadm-path are assigned roadm-path-impairment-id = 0

+Power sweep functionality is triggered when setting "power_range_db" in SI in the library. This defines a
+list of reference powers on which a new design is performed and propagation is triggered
+(only gnpy-transmission-example script).
+
+for example, with the following settings:
+
+  - ``power_dbm`` = 0 dBm
+  - max power of the amplifier = 20 dBm,
+  - user defined ``delta_p`` set by user = 3 dB
+  - 80 channels, so :math:`pch_{max}` = 20 - 10log10(80) = 0.96 dBm
+  - ``delta_power_range_db`` = [-3, 0, 3]
+  - power_sweep -> power range [-3, 0] dBm
+
+then the computation of delta_p during design for each power of this power sweep is:
+
+  - with :math:`p_{ref}` = 0 dBm, computed_delta_p = min(:math:`pch_{max}`, :math:`p_{ref}` + ``delta_p``) - :math:`p_{ref}` = 0.96 ;
+    - user defined ``delta_p`` = 3 dB **can not** be applied because of saturation,
+  - with :math:`p_{ref}` = -3 dBm (power sweep) computed_delta_p = min(:math:`pch_{max}`, :math:`p_{ref}` + ``delta_p``) - :math:`p_{ref}` =
+    min(0.96, -3.0 + 3.0) - (-3.0) = 3.0 ;
+    - user defined ``delta_p`` = 3 dB **can** be applied.
+
+so the user defined delta_p is applied as much as possible.

+The user can specify the amplifier configurations, which are applied depending on general simulation setup:
+- if the user has specified ``power_mode`` as True in Span section, delta_p is applied and gain_target is ignored and recomputed.
+- if the user has specified ``power_mode`` as False in Span section, gain_target is applied and delta_p is ignored.
+If the user has specified unfeasible targets with respect to the type_variety, targets might be changed accordingly.
+For example, if gain_target leads to a power value above the maximum output power of the amplifier, the gain is saturated to
+the maximum achievable total power.

+Fused
+~~~~~
+
+The user can define concentrated losses thanks to Fused element. This can be useful for example to materialize connector with its loss between two fiber spans.
+``params`` and ``loss`` are optional, loss of the concentrated loss is in dB. Default value is 0 dB.
+A fused element connected to the egress of a ROADM will disable the automatic booster/preamp selection.
+
+Fused ``params`` only contains a ``loss`` value in dB.

+
+Transceiver
+~~~~~~~~~~~
+
+Transceiver elements represent the logical function that generates a spectrum. This must be specified to start and stop propagation. However, the characteristics of the spectrum are defined elsewhere, so Transceiver elements do not contain any attribute.
+Information on transceivers' type, modes and frequency must be listed in :ref:`service file<service>` or :ref:`spectrum file<mixed-rate>`. Without any definition, default :ref:`SI<spectral_info>` values of the library are propagated.
+
+.. _service:
+
+Service JSON file
+-----------------
+
+Service file lists all requests and their possible constraints. This is derived from draft-ietf-teas-yang-path-computation-01.txt:
+gnpy-path-request computes performance of each request independantly from each other, considering full load (based on the request settings),
+but computes spectrum occupation based on the list of request, so that the requests should not define overlapping spectrum.
+Lack of spectrum leads to blocking, but performance estimation is still returned for information.

+Release change log
+==================
+
+Each release introduces some changes and new features.
+
+(prepare text for next release)
+ROADM impairments can be defined per degree and roadm-path type (add, drop or express).
+Minimum loss when crossing a ROADM is no more 0 dB. It can be set per ROADM degree with roadm-path-impairments.
+
+The transceiver output power, which was previously set using the same parameter as the input span power (power_dbm),
+can now be set using a different parameter. It can be set as:
+
+  - for all channels, with tx_power_dbm using SI similarly to tx_osnr (gnpy-transmission-example script)

+v2.9
+----
+
+The revision introduces a major refactor that separates design and propagation. Most of these changes have no impact
+on the user experience, except the following ones:
+
+**Network design - amplifiers**: amplifier saturation is checked during design in all cases, even if type_variety is
+set; amplifier gain is no more computed on the fly but only at design phase.
+
+Before, the design did not consider amplifier power saturation during design if amplifier type_variety was stated.
+With this revision, the saturation is always applied:
+If design is made for a per channel power that leads to saturation, the target are properly reduced and the design
+is freezed. So that when a new simulation is performed on the same network for lower levels of power per channel
+the same gain target is applied. Before these were recomputed, changing the gain targets, so the simulation was
+not considering the exact same working points for amplifiers in case of saturation.
+
+Note that this case (working with saturation settings) is not recommended.
+
+The gain of amplifiers was estimated on the fly also in case of RamanFiber preceding elements. The refactor now
+requires that an estimation of Raman gain of the RamanFiber is done during design to properly compute a gain target.
+The Raman gain is estimated at design for every RamanFiber span and also during propagation instead of being only
+estimated at propagation stage for those Raman Fiber spans concerned with the transmission. The auto-design is more
+accurate for unpropagated spans, but this results in an increase overall computation time.
+This will be improved in the future.
+
+**Network design - ROADMs**: ROADM target power settings are verified during design.
+
+Design checks that expected power coming from every directions ingress from a ROADM are consistent with output power
+targets. The checks only considers the adjacent previous hop. If the expected power at the input of this ROADM is
+lower than the target power on the out-degree of the ROADM, a warning is displayed, and user is asked to review the
+input network to avoid this situation. This does not change the design or propagation behaviour.
+
+**Propagation**: amplifier gain target is no more recomputed during propagation. It is now possible to freeze
+the design and propagate without automatic changes.
+
+In previous release, gain was recomputed during propagation based on an hypothetical reference noiseless channel
+propagation. It was not possible to «freeze» the autodesign, and propagate without recomputing the gain target
+of amplifiers.
+With this new release, the design is freezed, so that it is possible to compare performances on same basis.
+
+**Display**: "effective pch (dbm)" is removed. Display contains the target pch which is the target power per channel
+in dBm, computed based on reference channel used for design and the amplifier delta_p in dB (and before out VOA
+contribution). Note that "actual pch out (dBm)" is the actual propagated total power per channel averaged per spectrum
+band definition at the output of the amplifier element, including noises and out VOA contribution.
+
+v2.8
+----
+
+**Spectrum assignment**: requests can now support multiple slots.
+The definition in service file supports multiple assignments (unchanged syntax):
+
+  .. code-block:: json
+
+          "effective-freq-slot": [
+            {
+              "N": 0,
+              "M": 4
+            }, {
+              "N": 50,
+              "M": 4
+            }
+          ],
+
+But in results, label-hop is now a list of slots and center frequency index:
+
+  .. code-block:: json
+
+          {
+            "path-route-object": {
+              "index": 4,
+              "label-hop": [
+                {
+                  "N": 0,
+                  "M": 4
+                }, {
+                  "N": 50,
+                  "M": 4
+                }
+              ]
+            }
+          },
+
+instead of 
+
+  .. code-block:: json
+
+          {
+            "path-route-object": {
+              "index": 4,
+              "label-hop": {
+                "N": 0,
+                "M": 4
+              }
+            }
+          },
+
+
+
+**change in display**: only warnings are displayed ; information are disabled and needs the -v (verbose)
+option to be displayed on standard output.
+
+**frequency scaling**: A more accurate description of fiber parameters is implemented, including frequency scaling of
+chromatic dispersion, effective area, Raman gain coefficient, and nonlinear coefficient.
+
+In particular:
+
+1. Chromatic dispersion can be defined with ``'dispersion'`` and ``'dispersion_slope'``, as in previous versions, or
+with ``'dispersion_per_frequency'``; the latter must be defined as a dictionary with two keys, ``'value'`` and
+``'frequency'`` and it has higher priority than the entries ``'dispersion'`` and ``'dispersion_slope'``.
+Essential change: In previous versions, when it was not provided the ``'dispersion_slope'`` was calculated in an
+involute manner to get a vanishing beta3 , and this was a mere artifact for NLI evaluation purposes (namely to evaluate
+beta2 and beta3, not for total dispersion accumulation). Now, the evaluation of beta2 and beta3 is performed explicitly
+in the element.py module.
+
+2. The effective area is provided as a scalar value evaluated at the Fiber reference frequency and properly scaled
+considering the Fiber refractive indices n1 and n2, and the core radius. These quantities are assumed to be fixed and
+are hard coded in the parameters.py module. Essential change: The effective area is always scaled along the frequency.
+
+3. The Raman gain coefficient is properly scaled considering the overlapping of fiber effective area values scaled at
+the interacting frequencies. Essential change: In previous version the Raman gain coefficient depends only on
+the frequency offset.
+
+4. The nonlinear coefficient ``'gamma'`` is properly scaled considering the refractive index n2 and the scaling
+effective area.  Essential change: As the effective area, the nonlinear coefficient is always scaled along the
+frequency.
+
+**power offset**: Power equalization now enables defining a power offset in transceiver library to represent
+the deviation from the general equalisation strategy defined in ROADMs.
