Bold means I need to think about it more

Proto-Nebulonic to Late Proto-Nebulonic

 * /i/, /u/ > /e/, /o/ after an ejective
 * voiceless plosives convert to voiced at the end of words; voiced plosives delete at the end of words
 * ejectives > aspirated (word-initially before a vowel; between vowels)
 * ejectives > non-ejective (everywhere else)
 * plosives are realized aspirated before liquids (and nasals?)
 * apocope of final unstressed vowels (only in some environments: not after /j/ or /w/; not after vowels; not after plosive + liquid clusters; only after certain consonants?)
 * /ie/, /uo/ > /iː/, /uː/

Late Proto-Nebulonic to Old Nebulonic

 * i > j / _V (other than i or e)
 * u > w / _V (other than u or o; not after a liquid)
 * Diphthongization: voiceless unaspirated plosives become glides/lengthen the preceding vowel before consonants other than liquids, and word-finally. /p, b/ > /w/ after /a/, /o/. they lengthen /u/, and remain after /i/ and /e/. /t, d/: lengthen preceding vowel, which then diphthongizes. /k, g/ > /j/ after /a/, /e/. they lengthen /i/, and remain after /o/ and /u/.
 * LPN /VV/ > /Vː/
 * /oe, eo/ > /oː/
 * LPN /ei/, /iː/, /eː/ > /e͡i̯/
 * LPN /ou/, /uː/, /oː/ > /o͡u̯/
 * LPN /ai/, /ae/ > /a͡i̯/
 * LPN /au/, /ao/ > /a͡u̯/
 * LPN /ea/ > /æ͡a̯/
 * LPN /oa/ > /ɔ͡a̯/
 * e > j / _V (other than i, e, or a)
 * o > w / _V (other than u, o, or a; not after a liquid)
 * syncope, resulting in Accent Shift Step 1
 * accent shift step 2: aspirates attract stress, as do long vowels and diphthongs. what about consonant clusters, voiceless nasals, and voiceless liquids (in which case this shift would occur after the change to voiceless liquids and nasals, or it was still in progress. perhaps the change to voiceless liquids and nasals is from Late Proto-Nebulonic to Old?)? think of which sounds need to be distinguished from others more. compare with Sajem Tan.'''
 * aspirated plosives become fricatives: /pʰ, tʰ, kʰ/ > /ɸ, θ ~ s, x/
 * /j; w/ > /ʲɪ; ʷʊ/ before /u̯/ or /i̯/ respectively

Old Nebulonic to Modern Nebulonic

 * /Fr, Fl, rF, lF; Tr, Tl, rT, lT/ > /r̥; l̥/
 * /Fm; Fn/ > /m̥; n̥/
 * /p, t, k/ > /pʰ, tʰ, kʰ/ except when word-final in a word not stressed on the ultima
 * /b, d, g/ > /p, t, k/
 * /i/ > /ɨ/ after a bilabial consonant or a labialized consonant; before a labialized consonant or /Pw/ (/Cw/?) (/iː/ is unaffected)
 * long vowels shorten
 * /e/ > /e͡i̯/ before a palatalized consonant or /Pj/ (/Cj/?)
 * /o͡u̯/ > /o/
 * /a͡i̯, eaː, æ͡a; ɔ͡a, oaː, a͡u̯/ > /æ; ɑ/
 * /a/ > /æ/ before /j/, a palatalized consonant, or /Pj/ (/Cj/?)
 * /a/ > /ɑ/ before /w/, a labial consonant, a labialized consonant or /Pw/ (/Cw/?)
 * /a/ > /ɑ/ everywhere else
 * another accent shift to account for the low vowels, the aspirated plosives, and the voiceless liquids and nasals
 * /tj, tʲ, kj, kʲ; dj, dʲ, gj, gʲ; sj, sʲ, hj, hʲ/ > /t͡s; d͡z; h ~ ɧ/
 * /ʲɪ; ʷʊ/ > /ɨ/
 * /w, u̯, ʷ/ > /Ø/ after a bilabial consonant, after a liquid, and after /n/ at the start of a word
 * /w/ > /v/; /u̯/ > /v/ before a vowel
 * /ɸ/ > /f/; /θ ~ s/ > /s/; /x/ > /h/
