Deaffrication spreads in Eastern-A, which gets an orthographic update

['çeəʒi̥]
hyeaji

Both Eastern-B and Western have terminal schwa loss with compensatory gemination if the final consonant is not already a geminate, also orthographic updates:

['hea̯ɫː]
héall

['kɔʌ̯ɖɖʐ]
koëdsz

Eastern-A (maybe Northeastern or something?): Fricatives get lateralized:

['ʎ̝̊eəɮi̥]
hyeaji

Eastern-B (maybe Southeastern?): h//_V:

['ea̯ɫːə]
éall

Western: [ɔʌ̯]>[ɔː]:

['kɔːɖɖʐ]
kōdsz

Note: Corrected one missed change (error originally mine) in the outcomes here:

Northeastern: Devoiced elements in direct proximity to voiced ones become voiced
['ʎeə.ɮi]
hyéaji

Southeastern and Western: Long consonants degeminate following long vowels or diphthongs.

['ea̯ɫ]
éal

['kɔːɖʐ]
kódsz

Some unification of orthographic practices across all varieties also emerges.

Northeastern: Laterals become dentals.
['ʎeə.ði]
hyéaji

Southeastern: *ea̯ > jo.

['joɫ]
éal

Western: Retroflexes front to postalveolars.

['kɔːdʒ]
kódsz

Northeastern: Umlaut.

['ʎie.ði]
hyéaji

Southeastern: [ɫ] > [u]

['jou]
éal

Western: Diphthongisation [ɔː] > [uɛ]

['kuɛdʒ]
kódsz

Northeastern: [ʎi] > [j]

['je.ði]
hyéaji

Southeastern: Final [u] > [uβ]

['jouβ]
éal

Western: Final devoicing

['kuɛtʃ]
kódsz

Northeastern: Loss of terminal vowels with compensatory lengthening

['jeːð]
hyédh

Southeastern:Final devoicing spreads from Western.

['jouɸ]
youlh

Western: Affrication

['k͡xuɛtʃ]
kchoetsz

Each gets further orthographic revision.

Northeastern: Final fricatives (and liquids) become offglides.

['jeːə̯]
hyédh

Southeastern:Nothing of note happens.

['jouɸ]
youlh

Western: Deaffrication.

['xuɛʃ]
kchoetsz

New Word stolen from Uralo-Siberian. Means "to fly" and is nominalised with *-ki as bird and verbalised with *-jo as "to fall.

Try to split the language up into more different branches this time.

Language 1: Loss of terminal vowels with compensatory lengthening:

['teːŋ]
Téng

Language 1 Bonus Dialect: Vowel influenced by the lost final:

[tɛːŋ]
Tǽng

Language 2: The velar nasal denasalises between two oral vowels
['tegæki]
Tegäki

Language 3: [ŋj] > [ɲ]

['te.ɲø]
Tenjö

Language 1: Coda nasals lost, realized as nasalization on the vowel

[tẽː]
Téng

Language 1.5: Alveolar obstruents palatalize before front vowels (results in affrication of plosives)

[tʃɛːŋ]
Tǽng

Language 2: Voicing of intervocalic consonants

['tegægi]
Tegägi

Language 3: Vowels become rounded if the following syllable contains a rounded vowel

['tøɲø]
Tönjö

Language 1: Shortening of vowels in open monosyllables

[tẽ]
Teng

Language 1.5: [tʃ] > [ʃ]

[ʃɛːŋ]
Sǽng

Language 2: [g] > [j] before [i]

['tegæji]
Tegäġi

Language 3: [ɲ] > [ny] before [ø] resulting in two Finnish-style rounded vowels in hiatus

['tønyø]
Tönyö

Language 1: Vowel breaking in open stressed syllables:

[tiã]
Tiang

Language 1.5: The same shift spreads from Language 1, and the Orthography is harmonised between them

[ʃiaŋ]
Tiang

Language 2: [æji] collapses to [æi].

['tegæi]
Tegäġi

Language 3: [t] > [s] before front vowels.

[tsãõ]
tiang

Language 1.5: [ng] > [i] after front vowels

[ʃiɛi]
tiang

Language 2: [æ] > [e]

['teɰei]
tegäġi

['søɟʑø]
tönyö

Some spelling reforms happen, inspired by the French.

['søɟjø]

[ʒi'dʒɛi]
jdjaie

Language 2: [ee] > [eː]

['teːi]
têi

Language 3: [jø] > [jy]

['sø.ɟjy]
soejyoe

Language 1: Final vowels delete, shifting nasality (if any) onto the preceding onglide (if any), which turns into a syllabic nasal at the place of articulation of the glide

[tsŋ̩]
zaun

Language 1.5: d > ʒ / i_

A spelling reform occurs.

[ʒiʒ'ʒɛi]
gizgei

Language 2: Generation of offglide consonant following final high vowels
